FED-STD-141 Paint, Varnish, Lacquer And Related Materials: Methods Of Inspection, Sampling And TestingThis standard elaborates the methods used to determine the physical and chemical properties of paint, varnish, lacquer, and related materials. The purpose of this standard is to establish standardized testing methodologies and to eliminate unnecessary or undesirable variations in test results when evaluating a product??s adherence to specification requirements. If any variation or modification of the methods established in this standard is required by any specification, the procedures listed in the specification will take precedence. Any conflict between this standard and any particular specification will be resolved in favor of the specification.

4.4. Ingredients-certificate of compliance.

4.4.1 Ingredient requirements. When the specification has mandatory ingredient requirements

and the quantity of finished product is 50 gallons or 400 pounds or over, the contractor shall make

available to the Government representative a certificate of compliance from the ingredient supplier

for each ingredient, as applicable. The certificate of compliance shall cite the data or the location

and availability of data, that is the quality control data upon which the certificate is based. For

frequently replenished ingredients, normally mixed, blended, or combined in tanks or bins, the

contractor shall make available a record of ingredient supplier's certificate of compliance for each

replenishment. For products of critical end use such as ship-bottom paints, ingredients shall be

sampled and subjected to verification tests in a Government laboratory prior to start of manufacture,

when so required by the specification.

4.5. Testing and sampling.

4.5.1 Tests. All tests performed shall be in accordance with the applicable specifications. The

contractor is cautioned to refer to and to comply with all modifications of the specifications cited in

the contractual documents. If the contractor does not do testing, it shall be his responsibility to

furnish his designated testing facility with all pertinent contract information and modifications to

make certain that the testing establishment is adequately informed to accomplish all tests and make

accurate reports. Quantitative test results shall be reported to the same number of significant digits

as are used in stating the requirements of that property in the commodity specification. Qualitative

values shall be definitely stated. Results shall not be reported simply as "complies" or

"satisfactory," but in the same manner as the requirements. The test methods shall be reported by

reference to the applicable paragraph in the product specification or the method number when

referenced to a Federal or other test method standard.

4.5.2 Sampling. Unless otherwise specified, sampling shall be in accordance with ASTM D3925.

5. PRECISION

5.1 Data. No data.

6. NOTES

6.1 Paints and related products. While most paints and related products are bought by volume

(gallons and so forth), some products such as pigments, hard resins and, possibly, pastes are bought

by weight (pounds and so forth). The weights called out in this method are considered convenient

and representative amounts or lots for determining the extent of testing required. No specific

mathematical relationship is implied by the gallons and pounds called out in this method.
