1.1 本规程涵盖了以固化片材或薄膜形式制备胶粘剂和涂料样品，用于其他物理性能评估程序。 1.2 描述了铸造和固化的三个步骤( 注1 )用于隔热的所有类型的胶粘剂和涂料。当胶粘剂和涂料制造商推荐使用钢筋网时，应使用钢筋网制备试样。 注1: 术语“固化”主要用于表示由于挥发性物质损失而形成的条件，但也表示由于交联而导致的化学或物理性质的可能后续变化。 1.2.1 程序A 旨在提供适用于现场使用的预期绝缘材料的受控厚度样本，以及在其他方面与现场应用条件下可获得的等效厚度。 1.2.2 程序B 旨在提供厚度受控的自由薄膜试样，其两侧具有光滑表面。 某些类型的物理测试需要这种类型。 1.2.3 程序C 旨在提供具有一个光滑表面（如现场应用）的受控厚度的自由薄膜样品。 1.3 本规程的程序不用于评估应用性能。这些都包含在测试方法中 C461 和指南 C647 . 1.4 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 胶粘剂隔热涂层试样的制备方法将对测试期间获得的值产生影响。测试实验室应遵循本规程，以帮助确保试验方法的再现性，对于这些方法，需要胶粘隔热涂层的固化板或薄膜。

1.1 This practice covers the preparation of specimens of mastics and coatings in the form of cured sheets or films that are used in other procedures for evaluation of physical properties. 1.2 Three procedures are described for casting and curing ( Note 1 ) mastics and coatings of all types for thermal insulation. When reinforcing mesh in recommended by the mastics and coatings manufacturer, test specimens shall be prepared using reinforcing mesh. Note 1: The term “cure” is used primarily to denote the condition that develops as the result of loss of volatile matter but also to denote possible subsequent changes in chemical or physical properties due to crosslinking. 1.2.1 Procedure A is intended to provide a specimen of controlled thickness applied to the intended insulation for field use and equivalent in other respects to that obtainable under field application conditions. 1.2.2 Procedure B is intended to provide a free-film specimen of controlled thickness having smooth surfaces on both sides. This type is required for some types of physical testing. 1.2.3 Procedure C is intended to provide a free-film specimen of controlled thickness having one smooth surface (as field applied). 1.3 The procedures of this practice are not intended for the evaluation of application properties. These are covered in Test Methods C461 and Guide C647 . 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The method of preparation of test specimens of mastic thermal insulation coatings will have an impact upon values obtained during testing. Testing laboratories shall follow this practice to help ensure the reproducibility of test methods for which a cured sheet or film of a mastic thermal insulation coating is required.
