For a specific hazard statement, see Note 4. Active view current version of standard.

The safety precautions given in the Manual of Aggregate and Concrete Testing are recommended. 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. That values stated in sstm system may not be exact equivalents; therefore, each system must be used independently of the other, without combining the values in any way.
