EXECUTION
3.1
QUALITY ASSURANCE SAMPLES AND TESTS
**************************************************************************
NOTE: The need for and amount of quality assurance
testing should be based on site conditions and the
amount of geotextile being placed. EPA/600/R-93/182
indicates that a frequency of testing of once per
10,000 square meters (100,000 square feet) has been
used in the past for some large waste containment
facilities.
**************************************************************************
3.1.1
Quality Assurance Samples
The Contractor shall provide assistance to the Contracting Officer in the
collection of quality assurance samples. Samples shall be collected upon
delivery to the site for quality assurance testing [at the request of the
Contracting Officer.] [in accordance with ASTM D 4354, Procedure B. Lot
size for quality assurance sampling shall be considered to be the shipment
quantity of the product or a truckload of the product, whichever is
smaller. The unit size shall be considered one roll of geotextile.] [at a
frequency of one per 10,000 square meters 100,000 square feet]. Samples
shall be identified with a waterproof marker by manufacturer's name,
product identification, lot number, roll number, and machine direction.
The date and a unique sample number shall also be noted on the sample. The
outer layer of the geotextile roll shall be discarded prior to sampling a
roll. Samples shall then be collected by cutting the full-width of the
geotextile sheet a minimum of 1 meter 3 feet long in the machine direction.
Rolls which are sampled shall be immediately resealed in their protective
covering.
3.1.2
Quality Assurance Tests
The [Contractor shall] [Contracting Officer will] provide quality assurance
samples to an Independent Laboratory. Samples will be tested to verify
that geotextile meets the requirements specified in Table 1. Test method
ASTM D 4355 shall not be performed on the collected samples. Geotextile
product acceptance shall be based on ASTM D 4759. Tests not meeting the
specified requirements shall result in the rejection of applicable rolls.
