4. QUALITY ASSURANCE PROVISIONS

4.1. Responsibility for inspection.

Unless otherwise specified in the contract, the contractor is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified in the contract, the contractor may use her or his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements.

4.2. Responsibility for compliance.

All items shall meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the contractor's overall inspection system or quality program. The absence of any inspection requirements in this specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection as part of manufacturing operations is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known nonconforming material, either indicated or actual, nor does it commit the Government to accept nonconforming material.

4.2.1. Certificate of compliance.

Where certificates of compliance are submitted, the Government reserves the right to check test such items to determine the validity of the certification (see 4.2.1).

4 . 3 . Sampling for inspections and tests.

Sampling for inspections and tests shall be made in accordance with ASQ Z1.4 unless otherwise specified. The inspection levels and acceptable quality levels (AQL) shall be as specified. All cloth manufactured at one time shall be considered a lot for purposes of inspection and tests. Cloth samples shall be as specified in 4.5.1.1.

4.4. Quality conformance inspection.

The end item lot shall be sampled and inspected as specified in 4.6. Test reports showing compliance shall be submitted as part of the quality conformance inspections.

When conducting quality conformance inspections of first articles, the presence of any nonconformity or failure of any test shall be cause for rejection of the first article.

4.5. Certification.

As part of first article presentations and lot inspections, certificates of conformance shall be submitted to verify the characteristics of the aramid cloth, including blend, denier, non-charring properties, and conductive fiber. All certificates of compliance shall include:

Product description, including specification, type, class, form, etc. when applicable.

Quantity purchased.

Purchase source, address, and telephone number. Purchase date.

Lot number traceable to materials used in production. Contract number.

4.5.1. End item examination.

The examination of the end item shall be in accordance with 4.3.2.1 through 4.3.2.4.

4.5.1.1. Yard-by-yard examination.

Each roll in the sample shall be examined on the face side only. When the total yardage in the roll does not exceed 100 yards, the entire yardage in the roll shall be examined.

When the total yardage in the roll exceeds 100 yards, only 100 yards shall be examined.

The sample size shall be in accordance with the following:

Lot size Sample Size (rolls)

500 or less 3 500 to 3,200 8

3,201 to 10,000 13 Over 10,000 20

No more than one roll shall be taken from any shipping container unless the number of shipping containers in the lot is less than the required number of rolls, in which case all shipping containers shall be present in the sample. All nonconformities as defined in section III of FED-STD-4 that are clearly noticeable at normal inspection distance (3 feet) shall be scored and assigned demerit points as listed in 4.3.2.1.1 except as follows:

a. Only coarse yarns that exceed twice the normal yarn diameter shall be scored.

b. Mixed filling (shade bar) shall be scored only when resulting from wrong ply, wrong twist in the yarn, or off shade yarn.

c. Only knots and slubs that exceed 1/32 inch shall be scored.

No linear yard (increments of 1 yard on the measuring device of the inspection machine) from any one roll within the sample shall be penalized more than 4 points. The sample size shall be 20 rolls selected from 20 containers. The lot shall be unacceptable if the points per 100 square yards of the total yardage examined exceed 50 points. The lot shall be unacceptable if the points per 100 square yards of two or more individual rolls exceed 75 points. If one roll exceeds 75 points per 100 square yards, a second sample of 20 rolls shall be examined only for individual roll quality. The lot shall be unacceptable if one or more rolls in the second sample exceeds 75 points per 100 square yards. Point computation for lot quality and individual roll quality shall be as follows:

Total points scored in sample x 3600 Contracted width of cloth (inches) x total yards inspected = Points per 100 sq yds

4.5.1.1.1. Demerit points.

Demerit points shall be assigned as follows:

For nonconformities 3 inches or less in any dimension 1 point

For nonconformities exceeding 3 inches, but not exceeding 6 inches in any dimension 2 points

For nonconformities exceeding 6 inches, but not exceeding 9 inches in any dimension 3 points

For nonconformities exceeding 9 inches in any dimension 4 points

Objectionable odor (every occurrence) 4 points

Baggy, ridgy, or wavy cloth (every occurrence) 4 points

Width less than minimum specified (every occurrence) 4 points

Edge ravels when pulled outward (every occurrence) 4 points

Uneven weaving (every occurrence) 4 points

Slack or tight selvages.1 (every occurrence) 4 points

1 To determine the presence of unacceptable selvage conditions, the following procedure shall be observed: During the visual examination, the perch shall be stopped a minimum of three times for each roll in the sample, the tension removed, and the finished cloth examined for the selvage conditions. A waviness or ripples within the body of the cloth is an indication of slack or tight selvage.

4.5.1.2. Length examination.

4.5.1.2.1. Individual rolls.

During the yard-by-yard examination, each roll in the sample shall be examined for length. Any length found to be less than the minimum specified or more than 2 yards less than the length marked on the ticket shall be considered a nonconformity with respect to length. The lot shall be unacceptable if two or more rolls in the sample are nonconforming with respect to length.

4.5.1.2.2. Total yardage in sample.

The lot shall be unacceptable if the total of the actual lengths of rolls in the sample is less than the total of the lengths marked on the roll tickets. The rolls examined shall be those selected for the examination of individual rolls.

4.5.1.3. Shade examination.

During the yard-by-yard examination, each roll in the sample shall be examined for shade on the face side. When two or more rolls in the sample are off shade, shaded side to side, side to center, or end to end, it shall be cause for rejection of the entire lot represented by the sample.

4.5.1.4. Roll marking examination.

During the yard-by-yard examination each roll in the sample shall be examined for the following listed nonconformities:

a. Face stamping missing from either or both ends.

b. Face stamping on wrong side.

c. Not labeled in accordance with the Rules and Regulations Under the Textile Fiber

Products Identification Act.

Any roll not labeled or marked in accordance with the above shall be a nonconformity.

The lot shall be unacceptable if two or more of these nonconformities occur.

4.6. End item testing.

The methods of testing specified in Table 2 shall be followed. The physical and chemical values specified in section 3, except where otherwise specified, apply to the results of the determinations made on a sample unit for test purposes as specified in the applicable test method. The sample unit shall be 5 continuous yards, full width, of the dyed and finished cloth. All test reports shall contain the individual values utilized in expressing the final result. The lot size shall be expressed in units of 1 yard. The lot shall be unacceptable if one or more units fail to meet any requirement specified. The sample size (number of sample units) shall be as follows:

Lot size (yards) Sample size

800 or less 2 801 to 22,000 3 Over 22,000 5
