A-A-52443 Lubricant, Mold, Tire, Silicone Base Emulsion (Metric)This CID covers one type of silicone-base tire-mold lubricant furnished as a concentrated emulsion for further dilution with 100 or more parts of water. It is furnished in metal containers (with metal screw-top caps) of various sizes (see 2.8). The solution is used for spraying (or otherwise coating) tire molds, recapping or retread molds, tube plates, and the like. When applied, the solution will form a thin, inert film to prevent adhesion of "rubber stocks" and will assure a good surface finish of the cured compound.

2.8 Containers. The tire mold lubricant shall be furnished in metal containers with metal screw-caps. The containers shall be of .5 liter, 1 liter, or 5 liter capacity, or 1 pint, 1 quart, or 1 gallon capacity as specified in the acquisition document (see 5.2).

2.8.1 Leakage. Cans shall be subjected to an internal air pressure of 3 pounds per square inch gage in accordance with Method 5009 of MIL-STD-3010. Any loss of gage pressure, over a 30-minute period, shall be cause for rejection. When a water-soap solution or immersion is used, evidence of air leakage indicated by soap bubbles increasing in size or being blown away by escaping air, or evidence of a steady stream or a recurring succession of bubbles from any surface shall be cause for rejection. Rejected cans may have the affected area(s) repaired by a method or process equivalent to that used in the original manufacture and retested.

2.8.1.1 Closures. Cans furnished with closures shall be filled with a penetrating oil having a viscosity of 20 and closure secured. The filled can shall be suspended in an inverted position for

4 hours at a temperature of 120F. Alternatively, the closures may be tested by substitution of the product being packaged for the oil and following the same procedure.

2.9 Instructions for use. The supplier shall furnish with each individual container, an approved label properly affixed, or appropriate printed instructions for the dilution and application of the lubricant and any precautions to assure proper handling and use.

2.10 Identification markings. Identification markings shall be placed on the outside of the lubricant container and shall be permanent and legible and shall include as a minimum, the manufacturer’s CAGE code, the contract number, the part identification number (PIN) (see 5.3), and the national stock number (NSN). In addition, the container shall be labeled or marked “shake or stir well before using”.

2.11 Workmanship. Workmanship shall be such as to produce a quality product.

3. QUALITY ASSURANCE PROVISIONS.

3.1 Responsibility for inspection. The contractor is responsible for the performance of all inspections (examinations and tests).

3.2 Contractor certification. The contractor shall certify and maintain substantiating evidence that the product offered meets the salient characteristics of this CID and that the product conforms to the producer’s own drawings, specifications, standards, and quality assurance practices. Items with known defects shall not be submitted for Government acceptance. The Government reserves the right to require proof of such conformance prior to the first delivery and thereafter as may be otherwise provided for under the provisions of the contract.
