Standard Test Method for Measuring Mass per Unit Area of Turf Reinforcement Mats
SCOPE
1.1 This test method covers an index to the determination of mass per unit area of all turf reinforcement mats.
1.2 The values stated in SI units or other units shall be regarded separately as standard. The values stated in parentheses are provided for information only.
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.
