3. REGULATORY REQUIREMENTS.

3.1 This standard does not purport to address all of the safety problems, if any, associated with its use.

It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4. QUALITY ASSURANCE PROVISIONS.

4.1 Product conformance. The product provided shall meet the salient characteristics of this Commercial Item Description, conform to the producer’s own drawings, specifications, standards, and quality assurance practices, and be the same product offered for sale in the commercial market. The government reserves the right to require proof of such conformance.

4.2 Inspection requirements. The charcoal shall be inspected in accordance with ASTM D 1762 for the requirements of section 2 except granulation test procedures shall be as specified in 4.3.

4.3 Granulation test. The following granulation tests shall be made to determine compliance with the requirements of 2.4. Nest the designated sieves from top to bottom in order of decreasing size of opening and attach a receiving pan to the bottom sieve. Place a 100-gm sample on the upper sieve, cover, and shake for 25 minutes mechanically. The mechanical shaker shall be a single-eccentric type which imparts to the sieves a rotary motion and tapping action of uniform speed of 300 ± 15 gyrations and 150 ± 10 taps of the striker per minute. Weigh the portions retained on each sieve and calculate the percentage passing through each of the sieves.

5. PACKAGING. Preservation, packing, and marking shall be as specified in the contract or order (see 6.2).
