BS EN 13999-4:2007 胶粘剂.使用后低溶剂或无溶剂胶粘剂排放特性的快速测量方法.挥发性二异氰酸盐的测定

This European Standard specifies a procedure for the determination of volatile isocyanates in the exhaust air of an emission test chamber after application of a low-solvent or solvent-free adhesive as defined in EN 923. The method is based on chemosorption of volatile isocyanates with 1-(2-methoxyphenyl) piperazine (in the following: 1-2MP) impregnated filters with subsequent desorption and liquid chromatographic analysis. The method permits measurement of a wide range of organic compounds containing isocyanate functional groups (NCO), including isocyanate monomers. For testing of adhesives emissions mainly toluene diisocyanate (TDI) and methylene bis (4-phenyl isocyanate also known as 4,4-diisocyanato-diphenylmethane or MDI), are of concern. The method as described in this European Standard can be used for other isocyanates too, such as isophorone diisocyanate (IPDI) and 1,6-hexamethylene diisocyanate (HDI) - see ISO 16702. Isocyanate oligomers or prepolymers are not volatile enough to be detected in emission test chambers at room temperature.

Chlorofluorocarbon (CFC) compounds have been identified as agents contributing to the reduction of stratospheric ozone. It is incumbent upon the electronics industry, as a primary user of CFC solvents, to find alternative processes and materials which eliminate the need for CFCs. One such alternative is the substitution of water-soluble fluxes and aqueous cleaning for rosin fluxes and CFC cleaning.

ASTM D4499-07 热熔胶粘剂的热稳定性用标准试验方法

Hot-melt adhesives must generally be applied at relatively high temperatures in order that the adhesive viscosity is low enough that it can be readily handled in typical hot-melt equipment. Changes in the adhesive caused by exposure to the severe environment required during hot-melt processing will disrupt the adhesive application process and may affect the quality of the adhesive bond. Changes in adhesive viscosity may affect the quantity of adhesive dispensed by the applicator. Phase separation or changes in viscosity and color may be an indication of changes occurring in the adhesive which could affect the quality of the adhesive joint. A skin formed on the adhesive may eventually clog the applicator nozzle or die. The data generated in this test procedure are comparative in nature. Results can be useful in observing batch-to-batch variation or relative thermal stability of alternate adhesive formulations. Results can also be useful in selecting application equipment and establishing operating conditions for satisfactory handling of a particular hot-melt adhesive. Round-robin testing showed that the reproducibility of this test method can depend strongly on the characteristics of the adhesive being tested. Results showed that, for the particular adhesives tested in the round robin, the test method was well suited for testing the heat stability of the adhesives based on an EVA copolymer, a polyolefin, and a polyamide. However, because of poor reproducibility, the test method proved to be unsuitable for assessing the heat stability of the adhesive based on a block copolymer. Precision of this test method is discussed in Section 11. 1.1 This test method covers the evaluation of hot-melt adhesives with respect to the change in properties that occurs while the adhesive is aged in the molten state during hot-melt application. Melt properties monitored are viscosity, color, skin formation, and phase separation.1.2 The values stated in SI units are to be regarded as the standard.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.

Standard Test Method for Heat Stability of Hot-Melt Adhesives

ASTM D1994-07 热熔粘合剂酸值的测定用标准试验方法

Acidic hot-melt adhesives are useful in many applications, as the acid functionality can contribute to better substrate wetting and better adhesion to polar, nonporous surfaces. Acidic hot-melt adhesives are also quite corrosive to conventional iron and steel adhesive application equipment. The acid number determination will tell an equipment manufacturer if corrosion-resistant equipment for an application should be recommended. The need for corrosion-resistant equipment will vary depending on the acid number of the hot-melt adhesive and type of metal that will be bonded.1.1 This test method covers the determination of acid numbers of hot-melt adhesives.1.2 This test method is applicable for hot-melt and hot-melt/acid systems that are soluble under the conditions described. The hot melt must also give light- or medium-colored solutions when dissolved. If this is not the case another method must be used.1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.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. Specific caution statements are given in 7.1 and 7.2.

Standard Test Method for Fluid Tightness Ability of Adhesives Used on Threaded Fasteners

ASTM D3165-07 用单面搭接迭层板组件的拉伸负荷测定剪切时胶粘剂强度特性的标准试验方法

This test method is useful in that the joint configuration closely simulates the actual joint configuration of many bonded assemblies. Surface preparation of the adherends can affect the apparent shear strength of the adhesive and can be one of the variables under study. This test method is also useful as an in-process quality control test for laminated assemblies. In practice the laminated assembly is either made over size and test specimens removed from it or a percentage of the assemblies are destructively tested. The misuse of strength values obtained from this test method as design allowable stress values for structural joints could lead to product failure, property damage, and human injury. The apparent shear strength of an adhesive obtained from a given small single-lap specimen may differ from that obtained from a joint made with different adherends or by a different bonding process. The normal variation of temperature and moisture in the service environment causes the adherends and the adhesive to swell and shrink. The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion. 4.3.1 Even in small specimens, short-term environmental changes can induce internal stresses or chemical changes in the adhesive that permanently affect the apparent strength and other mechanical properties of the adhesive. The problem of predicting joint behavior in a changing environment is even more difficult if a different type of adherend is used in a larger structural joint than was used in the small specimen. The apparent shear strength measured with a single-lap specimen is not suitable for determining design allowable stresses for designing structural joints that differ in any manner from the joints tested without thorough analysis and understanding of the joint and adhesive behaviors. Single-lap tests may be used for comparing and selecting adhesives or bonding processes for susceptibility to fatigue and environmental changes, but such comparisons must be made with great caution since different adhesives may respond differently in different joints. Review Guide D 4896 for further discussion of concepts for interpretation of adhesive-bonded single-lap joint data.1.1 This test method (Note 1) is intended for determining the comparative shear strengths of adhesives in large area joints when tested on a standard single-lap-joint specimen and under specified conditions of preparation and testing. Adhesives respond differently in small versus large area joints (Note 2). Note 1While this test method is intended for use in metal-to-metal applications, it may be used for measuring the shear properties of adhesives using plastic adherends, provided consideration is given to the thickness and rigidityof the plastic adherends. Doublers or bonded tabs may be required for plastic adherends to prevent bearing failure in the adherends.Note 2This variation can be influenced by adhesive density, flow characteristics, cure rate, gel time, carrier composition, entrapped volatiles, volatiles released during cure, etc. and also by cure cycle variables including: temperature, time, pressure, rise rate to temperature, cool-down rate, etc. In addition to the processing variables joint size changes the level of constraint on the adhesive as well as the influence of induced tensile loads at the edge of the joint during mechanical or thermal loading.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.This standard does not purport to address all of the safety concerns, if any, associated with its use.

Standard Test Method for Strength Properties of Adhesives in Shear by Tension Loading of Single-Lap-Joint Laminated Assemblies

ASTM D7247-07a 升温时评定层压板制品中胶粘剂剪切强度的标准试验方法

A discussion of the issues and limitations associated with the measurement of strength properties of adhesive bonds in shear by compression loading is found in Test Method D 905. While various combinations of test temperature and heat exposure duration can be used, the provisions specified in 7.2.4 shall be based on the understanding that the objective of this test method is to evaluate adhesive bond performance just before wood begins to burn and the elevated temperature is selected to be slightly below the unpiloted ignition temperature for wood when taken into account the specific product and its end-use applications. When using this test method, consideration shall be given to the unique production conditions, such as wood moisture content, applied spread rate, press pressure, and curing temperature of the adhesive.1.1 This standard describes a test method for evaluating the comparative shear strength of a planar adhesive bond at both ambient and elevated temperatures relative to the performance of solid wood under the same conditions. The test method is based on the breaking load after the specimen is exposed to either ambient or a constant elevated temperature for a specified duration as described in Section . This standard does not preclude the development and implementation of other methods that provide equivalent performance meeting the intent of this method.1.2 This test method is intended for the evaluation of adhesives that can be used to assemble test specimens in accordance with Test Method D 905. The evaluation of other types of adhesives, such as the binder systems used for strand-based products, is beyond the scope of this test method.1.3 This test method is intended for the evaluation of adhesives as a component of laminated wood products at elevated temperatures. The evaluation of fire performance on fire-rated laminated wood products or assemblies is beyond the scope of this test method.1.4 While it is preferable to use solid wood specimens as described in Section 6 as the control, structural composite lumber products as defined in Specification D 5456 shall be permitted for use provided they are matched with the bonded specimens in accordance with Section 6 and the ignition temperature is not significantly lower than solid wood of the same species.1.5 The exact formulation of adhesive supplied to the manufacturer of laminated wood products shall be evaluated. Modifications to the adhesive formulation require a separate evaluation unless approved by the manufacturer of the laminated wood product, qualified agency, and code evaluation agency.1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.This standard does not purport to address all of the safety concerns, such as the fire hazard, 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.
