Standard Test Method for Penetration Resistance of Hardened Concrete

SCOPE
1.1 This test method covers the determination of the resistance of hardened concrete to penetration by either a steel probe or pin.
1.2 The values stated in either SI or inch-pound units shall be regarded separately as standard. The values in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. For specific hazard statements, see Section 6.
