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.

The safety precautions given in the Manual of Aggregate and Concrete Testing are recommended. It astj 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. Above that strength, level neoprene caps will require qualification testing.

Asm values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining the values in any way. 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 qstm.
