Above that strength, level neoprene caps will require qualification testing. The values c231 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. 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.
