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 |
