General Requirements10.1 All filling compounds manufacture
30、d in accordancewith this specification shall meet the following requirements:10.1.1 HomogeneityThe compound shall be homoge-neous and free of agglomerates.10.1.2 Color and OpacityThe compound shall be asnearly colorless as is commercially feasible, consistent with therequirements of the end products
31、 for which the filling com-pound is intended. In general, identification of cable memberscoated with filling compound shall not be significantly inhib-ited because of filling compound color or opacity.10.1.3 Color StabilityAfter aging a specimen of fillingcompound in a suitable container for a perio
32、d of 120 6 1h(5days) at a temperature of 130C (266F) in a static air oven,measure the compound color in accordance with Test MethodD 1500. Unless otherwise specified, the color of the agedcompound shall not exceed 2.5.10.1.4 Foreign MaterialThe compounds shall be free ofdirt, metallic particles, and
33、 other foreign matter.10.2 Other PropertiesOther property requirements suchas volatility (for example, Test Method D 6), thermal oxidativestability (for example, testing similar to Test Methods D 942 orD 3895), cone penetration (for example, Test Methods D 217),D4732022corrosion prevention (for exam
34、ple, Test Method D 1743), andthe like, shall be as agreed upon between the producer and thepurchaser.NOTE 1If Test Method D 6 is referenced, a test cycle of 22 h at 107C(225F) is recommended in lieu of the 163C (325F) temperaturerequired by Test Method D 6.11. Temperature Characteristics11.1 Raw mat
35、erial temperature characteristics, if needed,may be specified by use of pour point (for example, TestMethod D 97), drop-melting point (for example, Test MethodsD 127 and D 566), viscosity (for example, Test Methods D 88,D 445, and Practice D 2161), congealing point (for example,Test Method D 938), d
