They shall be homogeneous and essentially free from flaws, defects, pinholes, bubbles, seams, cracks and inclusions. 3.2 Color The molded components shall be black. 3.3 Properties The molded components and the material from which they are fabricated shall meet the requirements of Table 1. 4.0 4.1 4.1.1 Quality Assurance Provisions Classification Of Tests Qualification Tests Qualification tests are those performed on molded slabs and components submitted for qualification as satisfactory products and shall consist of all tests listed in this specification. 4.1.2 Acceptance Tests Acceptance tests are those performed on molded slabs and components submitted for acceptance under contract. Acceptance tests shall consist of the following: dimensions, dimensional recovery, tensile strength, ultimate elongation, heat shock and flammability. 4.2 4.2.1 Sampling Instructions Qualification Test Samples Qualification test samples shall consist of six molded slabs, 6 x 6 x 0.075 0.010 inches (152 x 152 x 1.9 .25 mm) and the number of molded components specified. The molded slabs shall be fabricated from the same lot of material and shall be subjected to the same degree of crosslinking as the molded components.

All rights reserved SPECIFICATION RT-1313 ISSUE 7 Page 3 4.2.2 Acceptance Test Samples Acceptance test samples shall consist of specimens cut from a molded slab 6 x 6 x 0.075 0.010 inches (152 x 152 x 1.9 .25 mm) and molded components selected at random in accordance with MIL-STD-105, inspection Level S-2, AQL 6.5 percent. The molded slab shall be fabricated from the same lot of material and shall be subjected to the same degree of crosslinking as the molded components. A lot of components shall consist of all molded components from the same lot of material, from the same production run and offered for inspection at the same time. 4.3 4.3.1 Test Procedures Dimensional Recovery Samples of molded components, as supplied, shall be measured for dimensions in accordance with ASTM D 2671. The samples then shall be conditioned for 10 minutes in a 200 5C (392 9F) oven or equivalent, cooled to room temperature and remeasured. 4.3.2 Elastic Memory A 6 x 1/8 inch (152 x 3.2 mm) specimen cut from a molded slab shall be marked with two parallel gauge lines 1 inch (25 mm) apart in the central portion of the specimen. The distance between gauge lines shall be recorded as the original length. A 2 inch (51 mm) portion of the specimen including both gauge lines then shall be heated for 5 minutes in a 200 5C (392 9F) oven or equivalent, removed from the oven and stretched within 10 seconds, until the gauge lines are 4 inches (102 mm) apart. The extended specimen shall be cooled to room temperature and released from tension. After 24 hours at room temperature, the distance between the gauge lines shall be measured and recorded as the extended length. The portion of the specimen including both gauge lines then shall be reheated for 5 minutes in a 200 5C (392 9F) oven or equivalent and the distance between gauge lines then shall be measured and recorded as the retracted length. Expansion and retraction shall be calculated as follows: E = Le - Lo x 100 Lo Le - Lr R = L - L x 100 e o Where: E R Lo Le Lr = = = = = Expansion (percent) Retraction (percent) Original Length [inches (mm)] Extended Length [inches (mm)] Retracted Length [inches (mm)] If this document is printed it becomes uncontrolled.

After completion of the conditioning and while still in the cold chamber, each specimen shall be bent around the mandrel through not less than 360 degrees within 10 2 seconds. The specimens then shall be visually examined for cracks. 4.3.5 Heat Shock Three 6 x 1/4 inch (152 x 6.3 mm) specimens cut from a molded slab shall be conditioned for 4 hours in a 225 5C (437 9F) mechanical convection oven with an air velocity of from 100 to 200 feet (30 to 60 m) per minute past the specimens. After conditioning, the specimens shall be removed from the oven, cooled to room temperature and bent through 360 degrees over a 3/8 inch (9.5 mm) diameter mandrel. The specimens then shall be visually examined for evidence of dripping or cracking. 4.3.6 Heat Aging Three specimens, prepared and measured in accordance with 4.3.3 shall be conditioned for 168 hours in a 150 3C (302 5F) mechanical convection oven with an air velocity of 100 to 200 feet (30 to 60 m) per minute past the specimens. After conditioning, the specimens shall be removed from the oven, cooled to room temperature, tested for tensile strength and ultimate elongation in accordance with 4.3.3. 4.3.7 Fluid Resistance Six specimens prepared and measured in accordance with 4.3.3 shall be completely immersed in each of the test fluids listed in Table 1 for 24 hours at the temperature specified. The volume of the fluid shall be not less than 20 times that of the specimens. After conditioning, the specimens shall be lightly wiped and then air-dried for 45 15 minutes at 23 3C (73 4F). The three specimens intended for the tensile strength and elongation tests shall then be tested for tensile strength and ultimate elongation in accordance with 4.3.3. The other three specimens shall be weighed before and after immersion and the weight change calculated as a percent. 4.4 Rejection And Retest Failure of any sample to comply with any one of the requirements of this specification shall be cause for rejection of the lot represented. Material which has been rejected may be replaced or reworked to correct the defect and them resubmitted for acceptance. Before resubmitting, full particulars concerning the rejection and the action taken to correct the defect shall be furnished to the inspector. If this document is printed it becomes uncontrolled.
