Meaning and Purpose
5.1 The tensile properties measured by this method are valuable for studying the behaviour of coatings under environmental stresses such as those arising from ageing and weathering. (See references (1-10).) 4

5.2 Tensile properties may vary with specimen thickness, preparation method, spacing, rate of load application, response of tensile tester and type of fixture used. Therefore, these factors need to be carefully controlled if precise comparative results are required.

ASTM D2370-16-2021 Standard Test Method for Tensile Properties of Organic Coatings

Scope of
1.1 This test method covers the determination of elongation, tensile strength and stiffness (modulus of elasticity) of organic coatings when tested as free films.

1.2 Values expressed in SI units are treated as standard values. The values given in parentheses are mathematical conversions of inch-pound units and are for reference only and are not considered standard values.

1.3 This standard is not intended to address all safety issues, if any, associated with its use. It is the responsibility of users of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
