ASTM D5934-96 用三点弯曲控制加载速率测定刚性和半刚性塑料试样弹性模量的标准试验方法

1.1 This test method covers the use of controlled rate of loading mechanical instrumentation for gathering and reporting the modulus of elasticity of thermoplastic and thermosetting resins and composite systems in the form of rectangular bars molded directly or cut from sheets, plates, or molded shapes. The data generated, using three-point bending techniques, may be used to identify the thermomechanical properties of a plastics material or composition using a controlled rate of loading mechanical instrument. Results obtained from this test method may or may not be comparable to results obtained using D 790. 1.2 This test method is intended to provide a means for determining the modulus of elasticity within the linear region of the stress-strain curve (see Fig 1). This test is conducted at standard temperature and pressure.1.3 Apparent discrepancies may arise in results obtained under differing experimental conditions. These apparent differences from results observed in another study can usually be reconciled, without changing the observed data, by reporting in full (as described in this test method) the conditions under which the data were obtained.1.4 The values stated in SI units are to be regarded as the standard. The values stated in parentheses are for information only.1.5 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 D6600-00(2017) 评定橡胶试验方法试验灵敏度的标准实施规程

5.1 Testing is conducted to make technical decisions on materials, processes, and products. With the continued growth in the available test methods for evaluating scientific and technical properties, a quantitative approach is needed to select test methods that have high (or highest) quality or technical merit. The procedures as defined in this practice may be used for this purpose to make testing as cost effective as possible. 5.2 One index of test method technical merit and implied sensitivity frequently used in the past has been test method precision. The precision is usually expressed as some multiple of the test measurement standard deviation for a defined testing domain. Although precision is a required quantity for test sensitivity, it is an incomplete characteristic (only one half of the necessary information) since it does not consider the discrimination power for the FP (or constituent) being evaluated. 5.3 Any attempt to evaluate relative test sensitivity for two different test methods on the basis of test measurement standard deviation ratios or variance ratios, which lack any discrimination power information content, constitutes an invalid quantitative basis for sensitivity, or technical merit evaluation. Coefficient of variation ratios (which are normalized to the mean) may constitute a valid test sensitivity evaluation only under the special condition where the two test methods under comparison are directly proportional or reciprocally related to each other. If the relationship between two test methods is nonlinear or linear with a nonzero intercept, the coefficient of variation ratios are not equivalent to the true test sensitivity as defined in this practice. See discussion of example in X1.1.4. The figure of merit defined by test sensitivity and its various classifications, categories, and types as introduced by this practice permits an authentic quantitative test sensitivity evaluation. 1.1 This practice covers testing to evaluate chemical constituents, chemical and physical properties of compounding materials, and compounded and cured rubbers, which may frequently be conducted by one or more test methods. When more than one test method is available, two questions arise: Which test method has the better (or best) response to or discrimination for the underlying fundamental property being evaluated? and Which test method has the least error? These two characteristics collectively determine one type of technical merit of test methods that may be designated as test sensitivity. 1.2 Although a comprehensive and detailed treatment, as given by this practice, is required for a full appreciation of test sensitivity, a simplified conceptual definition may be given here. Test sensitivity is the ratio of discrimination power for the fundamental property evaluated to the measurement error or uncertainty, expressed as a standard deviation. The greater the discriminating power and the lower the test error, the better is the test sensitivity. Borrowing from the terminology in electronics, this ratio has frequently been called the signal-to-noise ratio; the signal corresponding to the discrimination power and the noise corresponding to the test measurement error. Therefore, this practice describes how test sensitivity, generically defined as the signal-to-noise ratio, may be evaluated for test methods used in the rubber manufacturing industry, which measure typical physical and chemic......

ISO 14898:1999 塑料 聚氨酯生产用芳香异氰酸酯 酸度测定

This International Standard specifies methods for the measurement of the acidity of aromatic isocyanates and prepolymers used as polyurethane raw materials. Method A is a straightforward titration without a blank and is primarily applicable to products derived from crude or modified methylene-bis-(4-phenylisocyanate), polymethylene polyphenylisocyanates and toluene diisocyanate having moderate to high (> 100 μg/g ) levels of acidity. Method B is applicable to refined, crude or modified isocyanates derived from methylene-bis-(4-phenylisocyanate), polymethylene polyphenylisocyanate and toluene diisocyanate having low (< 100 μg/g ) levels of acidity, and a blank is employed. These methods can also be used for isomeric mixtures of toluene diisocyanate, methylene-bis-(4-phenylisocyanate) and polymethylene polyphenylisocyanate. Other aromatic isocyanates may be analysed by this method if precautions are taken to verify suitability.

ANSI/ASTM D6435:1999 塑料成材和型材剪切特性测试方法

This test method covers the determination of the mechanical properties of plastic lumber and plastic lumber shapes when loaded in shear at relatively low uniform rates of straining or loading. Plastic lumber and plastic lumber shapes are currently made predominately with recycled plastics where the product is nonhomogenous in the cross section. However, this test method would also be applicable to similarly manufactured plastic products made from virgin resins or where the product is nonhomogenous in the cross section. The values stated in inch-pound units are to be regarded as the standard. The SI units 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. 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.

Test Method for Shear Properties of Plastic Lumber and Shapes

ASTM D6435-99 塑料制材和型材剪切性能的标准试验方法

Shear tests provide information about the shear properties of plastic lumber when employed under conditions approximating those under which the tests are made. For many materials, there may be a specification that requires the use of this test method, but with some procedural-modifications that take precedence when adhering to the specification. Therefore, it is advisable to refer to that material specification before using this test method. Table 1 in Classification D 4000 lists the ASTM materials standards that currently exist. Shear properties are limited to shear strength only. In the case of a material that fails in shear by a fracture, the shear strength has a very definite value. In the case of a material that does not fail in shear by a fracture, the shear strength is based on the maximum load carried by the test specimen. Many plastic lumber materials may not fail in the classic shear mode; that is, separation of the test specimen into two pieces by failure along the critical shear surface. Shear tests provide a standard method of obtaining data for research and development, design, quality control, acceptance, or rejection under specifications. The tests cannot be considered appropriate for engineering design in applications differing widely from the load-time scale of the standard test. Such applications may require additional tests, such as impact, creep, and fatigue.1.1 This test method covers the determination of the mechanical properties of plastic lumber and plastic lumber shapes when loaded in shear at relatively low uniform rates of straining or loading. 1.2 Plastic lumber and plastic lumber shapes are currently made predominately with recycled plastics where the product is nonhomogenous in the cross section.
