3.0 REQUIREMENTS
3.1 Material: The splice encapsulation caps shall be fabricated from the materials specified on sheet 1 of this
specification. The materials shall be homogenous and essentially free from flaws, defects, pinholes, seams,
cracks and inclusions.
3.1.1 Color: The caps shall be black.
3.1.2 Properties of Molded Component: The molded component and the material from which it is fabricated
shall meet the requirements in Table 1.
3.1.3 Properties of Finished Caps: The finished caps shall meet the requirements of Table 2.
4.0 QUALITY ASSURANCE PROVISIONS
4.1 Classification of Tests:
4.1.1 Qualification of Tests: Qualification testing shall consist of all test listed in this specification.
4.1.2 Acceptance tests: Acceptance tests shall consist of those tests applicable to Test Groups A and F of
Table 2.
4.2 Sampling Instructions:
4.2.1 Qualification Test Samples: Qualification testing shall consist of six molded slabs, 6 x 6 x 0.075± .010
inches and 62 D-300-12 caps. The molded slabs shall be fabricated from the same lot of material and shall
be subjected to the same degree of cross-linking as the molded components.
4.2.2 Acceptance Test Samples: Acceptance test samples shall consist of finished caps selected at random in
accordance with ANSI/ASQC Z1.4, Inspection Level S-2, AQL 6.5%. A lot of finished caps shall consist
of all caps fabricated from the same lot of molded components, from the same production run, and offered
for inspection at the same time.
4.3 Test Procedures – Molded Slabs
4.3.1 Tensile Strength And Ultimate Elongation: Three specimens cut from a molded slab, using die D of
ASTM D 412, shall be tested for tensile strength and ultimate elongation in accordance with ASTM D 412.
4.3.2 Low-Temperature Flexibility: A 6- x ¼ inch specimen cut from a molded slab shall be mounted in a loop
position between movable, parallel, sets of jaws 2 ½ inches apart, mounted on a test fixture. Each end of
the specimen shall extend at least ¾ inch into a set of jaws and shall be firmly fastened. The specimen and
the test fixture shall be conditioned for four hours at –55 ± 2°C (-67 ± 4°F). While at this temperature, the
sets of jaws shall be moved rapidly from a 2 ½ inch to a 1 inch separation.
4.3.3 Heat Shock: Three 6 x ¼ inch specimens, cut from a molded slab, shall be conditioned for four hours in a
225 ± 5°C (437 ± 9°F) mechanical-convection oven in which air passes the specimens at a velocity of
100 to 200 feet per minute. After conditioning, the specimens shall be removed from the oven, cooled to
room temperature, and visually examined for evidence of dripping, flowing, or cracking.
4.3.4 Heat Aging:
4.3.4.1 Procedure A: Three specimens, prepared and measured in accordance with 4.3.1, shall be conditioned for
168 hours in a 175 ± 5°C (347 ±9°F) mechanical-convection oven in which air passes the specimens at a
velocity of 100 to 200 feet per minute. After conditioning, the specimens shall be removed from the oven,
cooled to room temperature, and tested for tensile strength and ultimate elongation in accordance with
4.3.1.
