A 15 inch wide sample is cut across the width of every 10th roll and brought to the Poly-Flex laboratory for testing. The sample is checked for visual defects and then tested according to the following:

Property	Test Method	Testing Frequency (min.)
Thickness	ASTM D 5199	50,000 sf
Mass per Unit Area	ASTM D 5261	50,000 sf
Density	ASTM D 1505	50,000 sf
Melt Index	ASTM D 1238	50,000 sf
Carbon Black Content	ASTM D 1603	50,000 sf
Tensile Strength	ASTM D 1682 or D 5035	50,000 sf
Transmissivity1	ASTM D 4716	100,000 sf

The laboratory manager reviews all test results to insure the product meets the specification. Any roll that does not meet the specification is immediately reported to the on-line quality control manager and the roll(s) is placed on hold for further evaluation.

3.5.2.   Geotextile

The manufacturer of the geotextile shall submit quality control test results for the geotextile rolls. The rolls must meet the specifications before they are accepted for production of geocomposites.

The geotextile manufacturer shall perform the following tests.

Property	Test Method	Testing Frequency (min.)
Unit Weight	ASTM D 5261	50,000 sf
Grab Tensile	ASTM D 4632	50,000 sf
Mullen Burst	ASTM D 3786	50,000 sf
Puncture Resistance	ASTM D 4833	50,000 sf
AOS	ASTM D 4751	100,000 sf
Permittivity	ASTM D 4491	100,000 sf

3.5.3.   Geocomposite

A 15 inch wide sample is cut across the width of every 20th roll and brought to the Poly-Flex laboratory for testing. The sample is checked for visual defects and then tested according to the following.

Property	Test Method	Testing Frequency (min.)
Transmissivity1	ASTM D 4716	100,000 sf
Peel Adhesion	ASTM D 413 or F904	100,000 sf

1. Transmissivity test is performed with the drainage net or the geocomposite between two steel plates at a hydraulic gradient of 1.0 and a normal pressure of 15,000 psf (718 kPa). The seating time is 15 minutes. The laboratory manager reviews all test results to insure the product meets the specification. Any roll that does not meet the specification is immediately reported to the on-line quality control manager and the roll(s) is placed on hold for further evaluation.
