Terminology3.1 Descriptions of Terms Specific to this Standard:3.1.1 flooding compoundsany of several materials used tofill the air spaces between the sheath elements of single andmulti-conductor insulated wires and cables or optical cables forthe purpose of excluding water and other undesirab

8、le fluids;especially with regard to telecommunications wire and cable,including optical cable, intended for outside aerial or under-ground installations.3.1.2 producerthe primary manufacturer of the material.3.1.3 suppliersjobbers and distributors as distinct fromproducers.4. Ordering Information4.1

9、 Orders for material under this specification shall includethe following information:4.1.1 Quantity (mass or volume) of each item,4.1.2 Generic name of the material, such as cable floodingcompound,4.1.3 How furnished (drums or barrels, blocks, etc.),4.1.4 Certification, if required (see Section 11).

10、4.1.5 This specification designation, and4.1.6 Any special requirements, as listed in 8.2 and 9.2, thatapply.5. Materials and Manufacture5.1 The material and manufacturing methods used shall besuch that the resulting products will conform to the propertiesand characteristics prescribed in this speci

11、fication.6. Compatibility with Other Materials6.1 It is the responsibility of the purchaser to ensure that theflooding compound ordered is suitable for the intended appli-cation and is compatible with any other components that maycome into contact with the flooding compound.1This specification is un

15、Chemical Composition7.1 The chemical composition of these materials is notspecified. The material may be of any chemical compositionsuitable for the intended purpose and which meets the require-ments of this specification as hereinafter stated.7.2 Once established, the producer shall not change thec

16、omposition of the compound in successive lots of materialwithout prior approval of the purchaser.8. Physical Properties8.1 Flooding compound furnished under this specificationshall inhibit the corrosion of any metallic wire and cableelements with which it comes in contact, while serving as aradial a

17、nd longitudinal barrier to moisture transmission. Con-tact of the flooding compound with any cable component shallnot cause degradation of performance of the cable component.The flooding compound shall display adhesive properties toprovide adhesion between metallic sheath elements and theouter jacke

18、t materials of wire and cable.8.2 Other Properties:8.2.1 Other physical properties requirements such as Vis-cosity (for example, Test Method D 3236), Flash Point (forexample, Test Method D92), Needle Penetration (for example,Test Method D 1321), Ring-and-Ball Softening Point (forexample, Test Method

19、 E28), and Heat Stability/ViscosityChange (for example, Test Method D 3236), may be specified,if needed, and shall be as agreed-upon between the producerand the purchaser.8.3 The purchaser (individual cable manufacturer or other)shall specify any other expected requirements needed to ensurecomplianc

20、e with such end-product requirements as cold-bend,low-temperature flexibility, and the like (for example, TestMethods D 4565).9. General Requirements9.1 All flooding compounds manufactured in conformanceto this specification shall meet the following requirements:9.1.1 HomogeneityThe compound shall b

21、e homogeneousand uniformly mixed.9.1.2 Foreign MaterialThe compounds shall be free ofdirt, metallic particles, and other foreign matter.9.2 Other Properties:9.2.1 Other raw material requirements such as Volatility (forexample, Test Method D6), Metals Content (for example, TestMethod D 482), adhesive

22、 property measurements, and corro-sion inhibiting characteristics may be specified, if needed, andshall be as agreed-upon between the producer and the pur-chaser.9.3 The purchaser (individual cable manufacturer or other)shall specify any other expected requirements needed to ensurecompliance with su

Quality Assurance10.1 Responsibility for Inspection and TestsUnless other-wise specified in the contract or purchase order, the producer isresponsible for the performance of all inspection and testrequirements specified her

24、ein. The producer may use his ownor any other suitable facilities for the performance of theinspection and test requirements specified herein, unless oth-erwise stated by the purchaser in the order or at the time of thecontract signing. The purchaser shall have the right to performany of the inspect

25、ions and tests set forth in this specificationwhere such inspections are deemed necessary to assure that thematerial conforms to prescribed requirements.10.2 Each producer shall establish written nominal valuesand tolerances for the material properties routinely checked.For properties not routinely
