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.

Above that strength, level neoprene caps will require qualification testing. Qualification testing is required for all elastomeric materials v1231 than neoprene regardless of the concrete strength.

The safety precautions given in the Manual of Aggregate and Concrete Testing are recommended. 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.

Qualification testing is required for all elastomeric materials other than neoprene regardless of the concrete strength. Above that strength, level neoprene caps will require qualification testing.

For a specific hazard statement, see Note 4.

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.

Warning— Concrete specimens tested with unbonded caps rupture more violently than comparable specimens tested with bonded caps. Warning —Concrete cylinders tested with unbonded caps rupture more violently than comparable cylinders tested with bonded caps.
