Standard Test Methods for Measuring the Opening Size of Geohazard Nettings

Importancia y uso:

5.1 Using a geohazard netting as a medium to retain rock particles necessitates compatibility between it and the adjacent rock. These test methods measure the opening size of a geohazard netting which may be used to estimate the largest size of rocks or other objects that may pass through the geohazard netting without transferring load to the wire mesh or wire net.

5.2 These test methods may be applied to other components of the geohazard netting, such as regularly spaced reinforcement elements or secondary mesh openings.

5.3 These test methods may also be used for quality control during the manufacturing process and quality assurance that materials supplied conform to project or material specifications.

Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.
