ASTM D5635/D5635M-11 屋面薄膜试样耐动态穿孔性能的标准试验方法

An important factor affecting the performance of membrane roofing systems is their ability to resist dynamic puncture loads. This test method provides a means to assess dynamic puncture resistance. This test method can be used to compare the dynamic puncture resistance of a single type of membrane as a function of a variety of insulation substrates or, conversely, to compare the resistance of a number of membrane specimens set on a single type of insulation. The effect of temperature on puncture resistance can be studied by conducting the test under controlled conditions using such equipment as an environmental chamber, oven, or freezer. The test method can be useful in developing performance criteria for membrane roofing systems. The test method can be useful in developing classifications of dynamic puncture resistance of membrane roofing systems. While it is considered that the results obtained by this laboratory test can afford a measure of the dynamic puncture resistance of membrane roofing systems in the field, (provided that service loads and temperature conditions are known) no direct correlation has yet been established. This test method can be useful for evaluating the dynamic puncture resistance of membranes used in vegetative roof systems.1.1 This test method covers the evaluation of the maximum dynamic puncture load that roofing membrane samples can withstand, without allowing the passage of water, when subjected to impact from a rigid object having a sharp edge. 1.2 This laboratory test can be conducted at any desired temperature using membrane samples manufactured in a factory or prepared in a laboratory. 1.3 Roof membrane specimens to which the test method is applicable include bituminous built-up, polymer-modified bitumens, vulcanized rubbers, non-vulcanized polymeric, and thermoplastic materials. 1.3.1 The applicability of this test method to these membrane specimens includes their use in vegetative roof systems. 1.4 This test method is not applicable to aggregate-surfaced membrane specimens; however, it is applicable to specimens having factory-applied granules. 1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM C1735-11 用应力松弛测定随时间变化密封胶模量的标准试验方法

The intent of this test method is to determine the time dependence of modulus in building joint sealants using two loading-unloading cycles to identify and mitigate any Mullins effect, and followed by a stress relaxation procedure to determine the time dependent modulus. This test method has found applications in screening the performance of building joint sealants since the modulus is one indicator of the ability of elastomeric building sealant to withstand environmental induced movements.1.1 This test method covers a procedure for measuring the time dependence of modulus in elastomeric joint sealants in a test specimen configuration described in Test Method C719. These sealant materials are typified by highly filled rubber materials. Any Mullins effect is first assessed and mitigated in two loading-unloading cycles. Time dependence of modulus in materials is then determined using a stress relaxation procedure. 1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM C1193-11a 密封胶的标准使用指南

This guide provides information and guidelines for consideration by the designer or applicator of a joint seal. It explains the properties and functions of various materials, such as sealant, sealant backing, and primer, among others; and, procedures such as, substrate cleaning and priming, and installation of the components of a sealed joint. It presents guidelines for the use and application of the various materials, design of a sealant joint for a specific application, and environmental conditions and effects that are known to detrimentally affect a sealant joint. The information and guidelines are also useful for those that supply accessories to the sealant industry and for those that install sealants and accessory materials associated with sealant use. In addition to the design and installation data in this guide, consult the sealant manufacturer about applications for its products and their proper use and installation. Considering the range of properties of commercially available sealants, the variety of joint designs possible, and the many conditions of use, the information contained herein is general in nature. It should be realized that a sealant and sealant joint are expected to have a design life during which they remain functional. However, a sealant and sealant joint will also have a service life. The intent is for service life to meet or exceed design life. There are many factors that can affect service life including type of sealant polymer, sealant formulation, compatibility with adjacent materials, installation techniques or deficiencies, sealant joint design (or lack thereof), proper maintenance (or lack thereof), and environmental exposure, among others. The designer of a joint seal should take the above into consideration when designing and specifying sealants for certain applications. The design life of a sealant or sealant joint should be considered in conjunction with the design life of the structure for which it is used. For example, a building owner may require a new courthouse building to have an expected design life of 50 years. Therefore, elements of the building''s exterior envelope should, with proper maintenance, be expected to perform for that time period. As a result of the information in 4.3 it should be realized that a sealant or sealant joint may not perform for that time period without proper maintenance. Proper maintenance could include replacement of localized sealant and sealant joint failures and conceivably complete sealant replacement, perhaps more than once, during that 50 year time period depending on a sealant''s polymer base and its particular formulation. Sealant replacement needs to be considered and when needed should be easily accomplished. To assist the user of the guide in locating specific information, a detailed listing of guide numbered sections and their descriptors are included in Appendix X2.1.1 This guide describes the use of a cold liquid-applied sealant for joint sealing applications. Including joints on buildings and related adjacent areas, such as plazas, decks, and pavements for vehicular or pedestrian use, and types of construction other than highways and airfield pavements and bridges. Information in this guide is primarily applicable to a single and multi-component, cold liquid-applied joint sealant and secondarily to a precured sealant when used with a properly prepared joint opening and substrate surfaces. 1.2 An elastomeric or non-elastomeric sealant described by this guide should meet the requirements of Specification C834, C920, or C1311. 1.3 This guide does not provide information or guidelines......

Standard Guide for Use of Joint Sealants

ASTM C1736-11 使用滚动装置对已安装的防水密封剂间接缝的粘附性进行无损评估的标准操作规程

Many parameters contribute to the overall performance of a sealant application. Some of the most significant parameters are sealant joint geometry, joint movement, joint design, sealant movement capability, quality of workmanship, quality of adhesive bond, and quality of the sealant material. If a sealant fails in adhesion, there is no straightforward procedure for determining the cause. The adhesive failure may be due to workmanship, the specific surface preparation used, the specific sealant used, poor joint design, poor bond chemistry, or other causes. Comprehensive information for the use of joint sealants is provided in Guide C1193. This technique may not produce useful results when the sealant is in compression. Comprehensive information regarding the impact of temperature on sealant joint dimensions may be found in Guide C1472.1.1 The non-destructive procedure described in this practice induces a depression (strain) in the sealant, creating an elongation of the sealant and a stress on the adhesive bond at the sealant to joint substrate interface. The primary purpose of the practice is to reveal sealant adhesion anomalies not discernible by visual examination, at the time of the evaluation, which may affect air infiltration resistance, or water infiltration resistance, or both, of the sealed joint. Note 18212;The nondestructive procedure may require immediate repair of the sealant bead, if failure is identified. Appropriate materials and equipment should be available for this purpose. 1.2 This practice is useful for the evaluation of adhesion of weatherseals in joints that are backed with compressible materials such as backer rod. This practice is not as useful in joints with solid backing. 1.3 The proper use of this practice requires a working knowledge of the principles of sealants as applied in movement joint applications. 1.4 A sealant fails to perform as a weatherseal when it allows air, or water, or both, to infiltrate the joint. This practice does not evaluate the performance of an installed sealant as a weatherseal. This practice is intended to only evaluate the characteristics of the adhesive bond in a particular installation. Note 28212;In addition to identifying adhesion characteristics of the sealant joint, this practice may provide the user with an indication of other characteristics and anomalies including, but not limited to, changes in sealant depth, insufficiently sized or configured backer rods, cohesive failures, entrapped air voids, and solid contaminants. Anomalies of this nature may be interpreted and addressed by the evaluator. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 The committee with jurisdiction for this standard is not aware of any comparable standard published by other organizations. 1.7 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D3791/D3791M-11 用于评估热度对沥青影响的标准操作规程

When asphalts are maintained at elevated temperatures in the presence of air, their characteristics may change. Certain blown asphalts also soften when maintained near, and particularly above, their final blowing temperatures under virtually air-free conditions. This may happen if the asphalt is overheated for application purposes. This practice provides a uniform heat-treatment procedure and methods for evaluating the effect of this treatment on some of the characteristics of asphalts. Changes observed when asphalts are overheated are not indicative of changes to be expected when asphalts are heated to normal application temperatures.1.1 This practice covers a procedure for evaluating some of the effects on asphalts of heating in the presence of little or no air. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

ASTM D6638-11 土工合成加筋和分段式混凝土构件（模制混凝土砌块）间的连接强度的测定的标准试验方法

The connection strength between geosynthetic reinforcement and segmental concrete block units is used in design of reinforced soil retaining walls. This test is used to determine the connection strength for the design of the connection system formed by segmental concrete block units and geosynthetic reinforcement layers in reinforced soil retaining walls. Performing a series of these connection tests at varying normal loads permits development of a relationship between connection strength and normal load. This relationship may be linear, bi-linear, or some other complex mathematical expression. This connection strength test is meant to be a performance test (laboratory or field), therefore, it should be conducted using full-scale system components. The conditions for the test are selected by the user and are not for routine testing. As a performance test on full-scale system components it accounts for some of the variables in construction procedures and materials tolerance normally present for these types of retaining wall systems.1.1 This test method is used to determine the connection properties between a layer of geosynthetic reinforcement and segmental concrete block units used in construction of reinforced soil retaining walls. The test is carried out under conditions determined by the user that reproduce the connection system at full-scale. The results of a series of tests are used to define a relationship between connection strength for a segmental unit-geosynthetic connection system and normal load.1.2 This is a performance test used to determine properties for design of retaining wall systems utilizing segmental concrete units and soil reinforcing geosynthetics, either geotextiles or geogrids. The test is performed on a full-scale construction of the connection and may be run in a laboratory or the field.1.3 The values stated in SI units are regarded as the standard. The values stated in inch-pound units are provided for information only.This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use.

This specification describes solvent release sealants for general caulking and sealing operations in building construction. However, it should be recognized by the user that not all sealants meeting this specification are suitable for all applications and all substrates and that there is no implication that the sealants are equivalent in all physical properties. Refer to Guide C1193 for information on the proper use of sealants meeting this specification.1.1 This specification describes the properties of a one-component solvent release sealant for use in building construction. These sealants are generally formulated to withstand a maximum joint movement of 7.5 % in extension and 7.5 % in compression of the nominal joint width. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 The committee with jurisdiction of this specification is not aware of any similar specification within ISO or any other organization.

ASTM C1472-10 确定密封层接缝宽度时位移和其他影响计算的标准指南

Design professionals, for aesthetic reasons, have desired to limit the spacing and width of sealant joints on exterior walls and other locations of new buildings. Analysis of the performance factors and especially tolerances that affect a sealant joint is necessary to determine if a joint will have durability and be effective in maintaining a seal against the passage of air and water and not experience premature deterioration. If performance factors and tolerances are not understood and included in the design of a sealant joint, then the sealant may reach its durability limit and failure is a distinct possibility. Sealant joint failure can result in increased building energy usage due to air infiltration or exfiltration, water infiltration, and deterioration of building systems and materials. Infiltrating water can cause spalling of porous and friable building materials such as concrete, brick, and stone; corrosion of ferrous metals; and decomposition of organic materials, among other effects. Personal injury can result from a fall incurred due to a wetted interior surface as a result of a failed sealant joint. Building indoor air quality can be affected due to organic growth in concealed and damp areas. Deterioration is often difficult and very costly to repair, with the cost of repair work usually greatly exceeding the original cost of the sealant joint work. This guide is applicable to sealants with an established movement capacity, in particular elastomeric sealants that meet Specification C920 with a minimum movement capacity rating of ± 12½ percent. In general, a sealant with less than ± 12½ percent movement capacity can be used with the joint width sizing calculations; however, the width of a joint using such a sealant will generally become too large to be practically considered and installed. It is also applicable to precured sealant extrusions with an established movement capacity that meets Specification C1518. The intent of this guide is to describe some of the performance factors and tolerances that are normally considered in sealant joint design. Equations and sample calculations are provided to assist the user of this guide in determining the required width and depth for single and multi-component, liquid-applied sealants when installed in properly prepared joint openings. The user of this guide should be aware that the single largest factor contributing to non-performance of sealant joints that have been designed for movement is poor workmanship. This results in improper installation of sealant and sealant joint components. The success of the methodology described by this guide is predicted on achieving adequate workmanship. Joints for new construction can be designed by the recommendations in this guide as well as joints that have reached the end of their service life and need routine maintenance or joints that require remedial work for a failure to perform. Guide C1193 should also be consulted when designing sealant joints. Failure to install a sealant and its components following its guidelines can and frequently will result in failure of a joint design. Peer reviewed papers, published in various ASTM Special Technical Publications (STP), provide additional information and examples of sealant joint width calculations that expand on the information described in this guide (2-5). For cases in which the state of the art is such that criteria for a particular condition is not firmly established or there are numerous..........

ASTM C834-10 胶乳密封料用标准规范

This specification covers two types and three grades of latex sealants as described in Section 4 that are formulated for general caulking and sealing operations in building construction. It should be recognized by the user that not all sealants meeting this specification are suitable for all applications and all substrates.
