1. SCOPE

1.1 Scope. This specification covers the requirements for impregnants suitable for use in sealing the voids found in cast or powder metal components which cause leaking of contained fluids. This specification covers the impregnants in bulk form only and not after they have been used to impregnate the metallic component.

1.2 Classification. The impregnants shall be of the following classes (see 6.7):

Class 1 - Suitable for service temperatures up to 300 degrees Fahrenheit (°F) (149 degrees Celsius (°C)).

Class 1a - Suitable for use on mortar shell castings up to 300°F (149°C).

Class 2 - Suitable for service temperatures up to 500°F (260°C).

Class 3 - Suitable for use where air pollution requirements apply and compatible with acrylic-nitrocellulose lacquer paint system up to 300°F (149°C).

NOTE: Classes 1, 1a, and 2 may or may not contain volatile photo-chemically reactive solvents and should not be used where air pollution requirements are enforced.

4. QUALITY ASSURANCE PROVISIONS

4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use 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 ensure supplies and services conform to the prescribed requirements.

4.1.1 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 the 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 defective material, either indicated or actual, nor does it commit the Government to accept defective material.

4.2 Classification of inspections. The inspection requirements specified herein are classified as follows:

• (a) Qualification inspection (see 4.3).
• (b) Quality conformance inspection (see 4.4).

4.3 Qualification inspection. Qualification inspection shall be conducted at a laboratory satisfactory to the Naval Sea Systems Command. Qualification inspection shall consist of the examinations of 4.3.1, 4.4 and the tests of 4.5, 4.6 and 4.7 including subparagraphs.

4.3.1 Material stability. The impregnating material shall meet the requirements of 3.6 and 3.7 when evaluated in accordance with 4.3.1.1 and 4.3.1.2.

4.3.1.1 Pot life test. Thermocuring materials shall be maintained for one month at 75 ± 5°F (24 ± 2.8°C). Anaerobic ion cured material shall be maintained, while under aeration, for one month at 45 ± 5°F (8 ± 2.8°C). At the end of the month an examination for evidence of thickening, curdling, and other objectionable property changes which prevent its use for the impregnation processes shall be made and the impregnant shall be tested to show compliance with 3.8.

4.3.1.2 Storage life test. Materials in unopened containers shall be examined at the end of one year and shall meet the requirements of 3.8 and 3.9 without any altering of the sample.

4.4 Quality conformance inspection. Quality conformance inspection shall consist of the tests specified in 4.5 through 4.5.5.5.

4.4.1 Sampling for quality conformance inspection. Quality conformance sampling shall be as follows:

4.4.1.1 Inspection lot. A sampling lot shall consist of all impregnant produced in a single production run and offered for delivery at one time.

4.4.1.2 Sample for conformance to preparation for delivery. Samples of filled containers shall be randomly selected from each lot in accordance with table I to verify compliance with this specification in regard to fill, closure and marking. Each type container shall be sampled separately when shipment consists of mixed lots.

TABLE I. Sampling for preparation for delivery.

4.4.1.3 Examination of filled containers. Each sample (filled container), selected as specified in 4.4.1.2, shall be examined for defects of construction of the container and closure, for evidence of leakage, and for markings as specified in MIL-STD-129. Filled containers shall also be weighed. The volume shall be established by the weight per gallon of the impregnant (see 4.5.3). Any container in the sample having one or more defects, or underfill, as determined by weight, shall result in the rejection of the lot. Rejected lots may be resubmitted for inspection provided the contractor has removed or repaired all nonconforming containers in the entire lot.

4.4.1.4 Inspection of curing. A sample from one container of the resin cured per manufacturers instruction shall be examined to determine that it meets the requirements specified in 3.8.

4.5 Test methods.

4.5.1 Test sample. The test sample shall consist of 1 gallon (3.8 liters) of the impregnant plus the necessary activator and curing instructions supplied by the manufacturer.

4.5.2 Test for filterable solids. The test sample shall be drawn through a Watman No. 5 filter paper or equivalent. The filter paper shall be examined visually during and after the filtration for evidence of loading by solids.

4.5.3 Weight per gallon. The weight per gallon of the resin shall be determined according to FED-STD-141, method 4184.1.

4.5.4 Cure tests. The impregnant shall meet the requirement of 3.8 when in contact with each of the following metals individually: aluminum, copper, iron, magnesium and zinc. The metals shall be in the form of fine dry chips. The chips shall be just covered with activated impregnant for not less than 24 hours and then cured according to the manufacturers instructions.

4.5.4.2 Shrinkage test. A sample of the material shall have its volume determined and then be cured under conditions recommended for the impregnant by its manufacturer. After cooling to room temperature, the volume of the cured material shall be measured. The change in volume, if any, shall not exceed the requirement of 3.4.

4.5.4.3 Weight loss. Not less than 5 cubic centimeters (cm²) cm³ of the activated Impregnant shall be carefully weighed on an analytical balance, cured in accordance with the manufacturers instructions, and reweighed for compliance with 3.4.
