General Requirements10.1 All filling compounds manufactured in accordancewith this specification shall meet th
31、e following requirements:10.1.1 HomogeneityThe compound shall be homoge-neous and free of agglomerates.D 4732 02 (2008)e1210.1.2 Color and OpacityThe compound shall be asnearly colorless as is commercially feasible, consistent with therequirements of the end products for which the filling com-pound
32、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 period of 120 6 1h(5days) at a tempera

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 other foreign matter.10.2 Othe
34、r PropertiesOther property requirements suchas volatility (for example, Test Method D6), thermal oxidativestability (for example, testing similar to Test Methods D 942 orD 3895), cone penetration (for example, Test Methods D 217),corrosion prevention (for example, Test Method D 1743), andthe like, s
35、hall be as agreed upon between the producer and thepurchaser.NOTE 1If Test Method D6is referenced, a test cycle of 22 h at 107C (225 F) is recommended in lieu of the 163 C (325 F) temperaturerequired by Test Method D6.11. Temperature Characteristics11.1 Raw material temperature characteristics, if n
36、eeded,may be specified by use of pour point (for example, TestMethod D97), 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), drop point (for example, Test MethodsD 56
37、6 and D 3954), or as otherwise agreed upon between theproducer and the purchaser.NOTE 2Although cited in 11.1, Test Method D 127 is “not” apreferred method for determining the melting point of wire and cablefilling compounds since results tend to be too high to be useful inpredicting material behavi
38、or in the cable filling process. However, thismay be a good test for quality control purposes.11.2 The purchaser (individual cable manufacture or other)shall specify any other expected temperature conformancerequirements (high and low) needed to assure compliance withsuch end-product requirements as
39、 cable drip-out temperature,cold-bend low-temperature flexibility, and the like (for ex-ample, Test Methods D 4565).12.

Quality Assurance13.1 Responsibility for Inspection and TestsUnless other-wise specified in the c
41、ontract or purchase order, the producer isresponsible for the performance of all inspection and testrequirements specified herein. The producer may use his ownor any other suitable facilities for the performance of theseinspection and test requirements unless otherwise stated by thepurchaser in the
42、order or at the time of contract signing.
