Con-tact of the filling compound with any cable component shallnot cause degradation of performance of the cable component.The filling compound shall display adhesive properties toprovide
28、 adhesion between metallic sheath elements and theouter jacket materials of wire and cable.9.2 Other Physical Properties:9.2.1 Other physical properties requirements such as FlashPoint (for example, Test Method D92), high-temperature drip/oil separation (syneresis) in the raw material state (forexam
29、ple, Test Method D1742), evaporation loss (for example,Test Method D972), and water resistance (for example, TestMethod D1264), and the like, shall be as agreed upon betweenthe producer and the purchaser.9.2.2 The purchaser (individual cable manufacturer orother) shall specify any other expected req
30、uirements needed toensure compliance with such end-product requirements ascold-bend, low-temperature flexibility, and the like.10. General Requirements10.1 All filling compounds manufactured in accordancewith this specification shall meet the following requirements:10.1.1 HomogeneityThe compound sha
31、ll 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 for which the filling com-pound is intended. In general, identification of cable memberscoated with filling co
32、mpound 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 temperature of 130 C (266 F) in a static air oven,measure the compound color in accor
33、dance with Test MethodD1500. 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.D4732 13210.2 Other PropertiesOther property requirements suchas Volatility (for example
34、, Test Method D6),Thermal OxidativeStability (for example, testing similar to Test Methods D942 orD3895), Cone Penetration (for example, Test Methods D217),Corrosion Prevention (for example, Test Method D1743), andthe like, shall be as agreed upon between the producer and thepurchaser.NOTE 1If Test
35、Method D6 is referenced, a test cycle of 22 h at 107 C(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, such as PourPoint (for example, Test Method D97), Drop-Melting Point(for examp
36、le, Test Methods D127 and D566), Viscosity (forexample, Test Methods D88, D445, and Practice D2161),Congealing Point (for example, Test Method D938), DropPoint (for example, Test Methods D566 and D3954), if neededshall be as agreed upon between the producer and the pur-chaser.NOTE 2Although cited in
37、 11.1, Test Method D127 is “not” a preferredmethod for determining the melting point of wire and cable fillingcompounds since results tend to be too high to be useful in predictingmaterial behavior in the cable filling process. However, this may be a goodtest for quality control purposes.11.2 The pu
38、rchaser (individual cable manufacture or other)shall specify any other expected temperature conformancerequirements (high and low) needed to assure compliance withsuch end-product requirements as cable drip-out temperature,cold-bend low-temperature flexibility, and the like (forexample, Test Methods

40、 that thecompound must be compatible with when tested in accordancewith Test Method D4568.13. Quality Assurance13.1 Responsibility for Inspection and TestsUnless other-wise specified in the contract or purchase order, the producer isresponsible for the performance of all inspection and testrequireme
41、nts specified herein. The producer shall use his ownor any other suitable facilities for the performance of theseinspection and test requirements unless otherwise stated by thepurchaser in the order or at the time of contract signing. Thepurchaser shall have the right to perform any of the inspectio
42、nsand tests set forth in this specification where such inspectionsare deemed necessary to ensure that the material conforms tothe prescribed requirements.13.2 Each producer shall establish written nominal valuesand tolerances for the material properties routinely checked.For properties not routinely
