ASTM C, Test equipment Controls

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. SI units are shown in brackets. Active view c131 version of standard. 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. Qualification testing is required for all elastomeric materials other than neoprene regardless of the concrete strength.

Combining values from the two systems may result in non-conformance with the standard. Above that strength, level neoprene caps will require qualification testing.
