CLASSIFICATION (TEMPERATURE IDENTIFICATION)
24、Temperature requirement is by class as noted in Table 1. It is the responsibility of the customer to determine the “Class“ to be used for any application. Temperature ratings are to be considered the minimum service temperature required. It is the responsibility of the supplier to properly designate
25、 the service temperature of their product and provide the necessary data to the performance criteria in this specification when submitting to the customer for approval. Verification of any and all of the data submitted by the supplier is at the discretion of the customer. Table 1 - Temperature class

TESTS PROCEDURES 7.1 Sampling If it is not specified, the sample size must be five. The suggested dimension of the sample is 10 mm minimum, however, if the m
30、anufacturer is supplying sizes other than 10 mm, the customer may request other sample sizes. Selection must be representative of the current production for each test and test results should be reported. Precondition/equilibrate dry samples to 23 C 5 C and 50% 5% relative humidity for a minimum of 2
31、4 hours prior to testing unless otherwise noted. 7.2 Sample/Specimen Preparation 7.2.1 Tape Assemble a bundle of wire 300 mm or greater (300 to 450 mm recommended) in length of an appropriate number and size to approximate a diameter of 10 mm as designated by customer. Wire sizes and insulation type
32、s will be specified by the customer. If specified, cover the bundle with a piece of 10 mm diameter convoluted tubing of the same length as the bundle. Note that for the Heat Aging and Temperature/Humidity Cycling tests, the appropriate wire type and tubing with the same operation temperature as the
33、tape in question must be used; for other tests, it may be appropriate to use wire types and/or tubing with different operation temperatures. Wrap the tape to be tested around the bundle with a 50% overlap. 7.2.2 Extruded Tube Assemble a bundle of wire 300 mm or greater (300 to 450 mm recommended) in
34、 length of wire of an appropriate number and size to approximate a diameter of 10 mm or as specified by customer; in the absence of such specification, assemble the bundle so that its diameter is 80% of the diameter of the tubing to be tested. Wire sizes and insulation types will be specified by the
35、 customer. Cover the bundle with a piece of extruded tube of the same length as the bundle. Note that for the Heat Aging and Temperature/Humidity Cycling tests, the appropriate wire type with the same continuous operating temperature must be used with the extruded tube being tested as specified by t
36、he customer or test method; for other tests, it may be appropriate to use wire types with different operation temperatures. SAE INTERNATIONAL J2192 JUN2016 Page 6 of 14 7.2.3 Textile Tube Assemble a bundle of wire 300 mm or greater (300 to 450 mm recommended) in length of an appropriate number and s
37、ize to approximate a diameter of 10 mm or as specified by customer; in the absence of such specification, assemble the bundle so that its diameter is 80% of the diameter of the tubing to be tested. Wire sizes and insulation types will be specified by the customer. Cover the bundle with a piece of te
38、xtile tube of the same length as the bundle. Note that for the Heat Aging and Temperature/Humidity Cycling tests, the appropriate wire type with the same continuous operating temperature must be used with the textile tube being tested as specified by the customer or test method; for other tests, it
39、may be appropriate to use wire types with different operation temperatures. 7.3 Heat Aging 7.3.1 The material shall withstand temperature according to class noted in Table 3, and tested according to the procedure described in 7.3.2. 7.3.2 Place 30 pieces of 450 mm long test specimens of each sample
40、in a forced air convection oven (Type II as specified in ASTM D 5423, with air exchange rate of 100 to 200 per hour) at the sample maximum class temperature (refer to Table 3) for the duration of time interval.

42、ve humidity for at least 4 hours. 7.3.4 Wrap each of the conditioned test specimens around a mandrel with a diameter equal to four times the nominal ID of the test specimen at a uniform rate of one turn per 10 seconds. After 1,500 hours of heat aging and at 500-hours intervals to 3,000 hours, bend t
43、he specimens around a mandrel with a diameter equal to ten times the nominal ID of the test specimen at a uniform rate of one turn per 10 seconds. Visually inspect the sample on each specimen for any sign of degradation. Record and report any change in appearance and signs of degradation (e.g., crac
44、ks, melting, fading, etc.). Perform any quantitative measurements (e.g., length of any cracks or flagging sections, etc.) as requested by the customer. 7.4 Temperature/Humidity Cycling 7.4.1 Place test specimens in an environmental chamber and set the cycling sequence as following for three cycles.

47、7.7.4 Visually inspect the sample on each specimen for any sign of degradation after 1, 24, 48, and 72 hours. After 72 hours, wrap each specimen a complete 360 degrees around a mandrel with a diameter equal to four times the nominal ID of the test specimen at a uniform rate of one turn per 10 second
48、s. Record and report any change in appearance, signs of degradation or loss of flexibility. Perform any quantitative measurements (e.g., length of any cracks or flagging sections, etc.) as requested by the customer. 7.8 Fogging 7.8.1 Conduct the Fogging Test according to SAE J1756 using either the P
49、hotometric Method or the Gravimetric Method per agreement between customer and the supplier. 7.8.2 The test duration is to be specified by the customer. 7.8.3 Report Fog Number when using the Photometric Method; and Fog Mass when using the Gravimetric Method or as required by the customer. 7.9 Component Compatibility 7.9.1 Assemble components and test as specified by customer
