3 Terms and definitions

The terms and definitions defined in GB/T 16309 and the following apply to this document.

3.1 Hot water performance

A comparative method of testing product aging performance (mass loss, strength loss) by placing the product in hot water at a set temperature for a long time.

test.

3.2 Heat-rain performance

A test that simulates the durability of products under rain and sun cycles.

3.3 Soak-dry performance

A comparative test to measure the aging performance of products under soak-dry cycles.

3.4

A test to measure the change in product appearance under high temperature-low temperature cycles.

3.5
