ASTM C1231

Above that strength, level neoprene caps will require qualification testing. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Unbonded neoprene caps of a defined hardness are permitted to be used for testing for a specified maximum number of reuses without qualification testing up to a certain concrete compressive strength level. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
