24、SCABLE COMPONENTS AND COMPLETEDCABLES4. Scope4.1 Dimensional measurements include, but are not limitedto measurements of insulation and jacket thicknesses, tape andarmor thicknesses, conductor diameters, DODs, core diam-eters, overall diameters, etc.5. Significance and Use5.1 Dimensional measurement
25、s, properly interpreted, pro-vide information with regard to the conductors, insulation, orjacket. The dimensional measurements provide data for re-search and development, engineering design, quality control,and acceptance or rejection under specifications.6. Diameters6.1 Measure diameters of essent
26、ially round items (such asinsulated or uninsulated conductors) using any type of mi-crometer reading to at least 0.001 in. (0.025 mm) with eachdivision of a width that facilitates estimation of each measure-ment to 0.0001 in. (0.0025 mm). Take a minimum of tworeadings, essentially at right angles to
27、 each other, and averagethe results.6.2 In case of dispute, optical methods as described in TestMethods D3032 shall be used as the referee method.NOTE 1For insulated conductors with dual insulation (for example,foam-skin), the DOD of the inner layer must be measured using the opticalmethods of Test
28、Methods D3032.6.3 Measure the approximate or effective diameters ofnon-circular cross sections (such as, irregular or oval cables orcable cores) by the use of strap gauges.6.4 Precision and BiasThe precision and bias of thismethod for measuring diameters are in accordance with TestMethods D2633.7. T
29、hicknesses7.1 Measure insulation thickness using appropriate methodsspecified in Test Methods D2633, except that the micrometeraccuracy described in 6.1 is required. A pin gauge having theaccuracy of the micrometers as specified in 6.1 is acceptablefor thickness measurements made on tubular sections
30、 ofinsulation removed from conductors. Optical methods (asspecified in 6.2) are also permitted.7.2 Measure jacket thickness using appropriate methodsspecified in Test Methods D2633, except that the micrometeraccuracy specified in 6.1 is required. In determining thethickness of jackets applied over c
31、orrugated shields or armors,measurements must be made in the corrugation impressions(thinnest jacket spots). Optical methods (as specified in 6.2) arealso permitted.7.3 Precision and BiasThe precision and bias of thismethod for measuring thickness are in accordance with TestMethods D2633.NOTE 2For d
32、esignated purposes (such as, process control, etc.),continuous uniformity thickness gauges or measuring devices may beemployed during processing to provide running records of jacket thick-nesses. Record charts are normally maintained for a minimum of sixmonths.8. Eccentricity8.1 Calculate eccentrici

Scope10.1 Physical and environmental tests for insulations andjackets include, but are not limited to determination of some orall of the properties covered in Sections 12-25.11. Significance and Use11.1 Physical tests, properly interpreted, provide informa-tion w

Melt Flow Rate ChangePolyolefin Materials12.1 Raw Material BaselineMelt flow rate for insulationand jacket materials obtained from finished cable must becompared with the flow rates for corresponding raw materials.Determine the flow rates for the basic insulating and jacketin
39、graw materials in accordance with the requirements of TestMethod D1238. Standard conditions of test shall be as pre-scribed by the product specification. If possible, obtain samplesof raw materials before or during the extrusion process (but notafter heating). Since insulating and jacketing raw mate
40、rials arenormally obtained and used in bulk, it is usually difficult if notimpossible to relate a particular lot of raw material with aparticular reel of finished wire or cable; accordingly, averageraw materials values shall be established as necessary for anappropriate manufacturing time frame, unl
41、ess otherwise agreedupon between the producer and the purchaser.12.2 Insulation MaterialPerform tests on insulation re-moved from finished conductors. Note that thin wall and finegauge insulations shall be handled carefully because of en-trapped air. In the case of insulation in filled cable, thepre
42、ferred method is to obtain insulating material from conduc-tors before they are exposed to the filling operation. Ifnecessary, conductors obtained from completed filled cableshall be wiped dry and free of grease or foreign material usinga dry cloth (without solvent). Chop the insulation, strippedfro
43、m a conductor, as necessary to obtain specimens suitable fortesting (approximately3gofmaterial is required for each test).Test the chopped material as required byTest Method D1238 todetermine a melt flow rate. Run three tests and average theresults. Standard conditions of test shall be as indicated
44、in 12.1.12.3 Jacket MaterialJacket material used for this testmust be free of filling or flooding compound. Soft filling orflooding compounds shall be removed by thoroughly wipingthe jacket specimen using a clean dry cloth (without solvent);harder filling or flooding compounds shall be removed bycut
45、ting. Buffing is permitted to be used as a finishing operationto ensure clean and dry specimens. Use jacketing materialremoved from completed cable for performing tests. Chop thejacket material removed from the cable as is necessary toobtain specimens suitable for testing (approximately3gofmaterial
46、is required for each test). Test the chopped material asrequired by Test Method D1238 to determine a melt flow rate.Run three tests and average the results. Standard conditions oftest shall be as indicated in 12.1.12.4 CalculationCalculate the percent increase in flowrate as follows:I 5M22 M1M13 100

Perform tests in accordance with Test MethodD638 to determine such properties as tensile strength (nomi-nal), yield strengt
49、h, and percentage elongation at break. Thespeed of testing shall be as prescribed by the product specifi-cations.13.2 Jacket MaterialProvide test specimens by die cut-ting jacket segments removed (cut) from finished cable. Per-form testing in accordance with Test Method D638 to deter-mine such properties as tensile strength (nominal), yieldstrength and percentage elongation at break.
