1.1这些试验方法包括测定玻璃和微晶玻璃的弯曲断裂模量。 1.2这些试验方法适用于退火和预应力玻璃以及各种形式的微晶玻璃。描述了替代试验方法；所用的试验方法应根据试验目的和代表材料的试样的几何特征确定。 1.2.1试验方法A是平板玻璃断裂模量的试验。 1.2.2试验方法B是玻璃和微晶玻璃断裂模量的比较试验。 1.3试验方法按以下顺序出现: 小节 试验方法A 6至9 试验方法B 10至15 1.4 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和健康实践，并确定监管限制的适用性。 第10节和A1.5、A2.3.3、A2.4.3和A2.5.3中给出了具体的危险说明。

1.1 These test methods cover the determination of the modulus of rupture in bending of glass and glass-ceramics. 1.2 These test methods are applicable to annealed and prestressed glasses and glass-ceramics available in varied forms. Alternative test methods are described; the test method used shall be determined by the purpose of the test and geometric characteristics of specimens representative of the material. 1.2.1 Test Method A is a test for modulus of rupture of flat glass. 1.2.2 Test Method B is a comparative test for modulus of rupture of glass and glass-ceramics. 1.3 The test methods appear in the following order: Sections Test Method A 6 to 9 Test Method B 10 to 15 1.4 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 hazard statements are given in Section 10 and A1.5, A2.3.3, A2.4.3 and A2.5.3.
