Referenced Documents purchase separately The documents listed qstm are referenced within the subject standard but are not provided as part of the standard.

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 cylinders tested with unbonded caps rupture more violently than comparable cylinders aatm with bonded caps. Qualification testing is required for all elastomeric materials other than neoprene regardless of the concrete strength.
