ASTM C1231

Unbonded neoprene caps of a defined hardness are permitted to be used for testing for a specified maximum number of reuses c231 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.

Qualification testing is required for all elastomeric materials other than neoprene regardless of the concrete strength. 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.
