31、s are given for each test in this specification. A greater number of samples maybe required by the test request/order. However, no part or device may be represented as having met this specification unless the minimum sample size has been tested and all samples of the group tested have met the applic
32、able Acceptance Criteria for that test.

35、of 36 4.3 Equipment Neither this list nor the list in each test section is all-inclusive. It is meant to highlight specialized equipment or devices with particular accuracy requirements. Many other items of customary laboratory equipment and supplies will also be required. NOTE: On requirements: Use
36、 of equipment with a lesser range is acceptable for specific tests where the required range for that test can be met. The equipment range specified does not preclude use of equipment with a larger range, but the accuracy must remain within the specified tolerance. For example, a DMM with a range of
37、0 to 100 V could be substituted for one specified as 0 to 50 V, with the provision that the accuracy could be maintained as r0.5% of the 50 V full scale, or 0.25 V, not 0.5% of the 100 V full scale of the substituted equipment.

For example, even though a wire diameter specified as 0.1 mm might actually be the same as one specified as 0.10 mm,
41、calipers capable of 0.01 mm resolution may be used to measure the first wire but a micrometer with 0.001 mm resolution is required to measure the second wire. 4.5 Test Repeatability and Calibration All equipment used for test sample evaluation shall be calibrated and maintained according to the appl

44、s of this specification is intended to demonstrate that the design and construction of the components and connector systems tested are capable of operating in their intended vehicle environment and application. 5. TEST AND ACCEPTANCE REQUIREMENTS 5.1 General The tests detailed in this specification
45、are qualitative in nature and are not expected to stress any part beyond its anticipated application limit, except where tests to failure are specified. The test procedures that follow were written as stand-alone tests and may be used as such. 5.1.1 Performance Requirements Trailer tow connection sy
46、stems must meet all performance test requirements. 5.1.2 Dimensional Characteristics Part construction shall conform to the dimensions, shape, and detail attributes specified on the latest revision of the applicable part drawing(s). 5.1.3 Material Characteristics Parts are intended to be in their “a
47、s furnished for vehicle assembly“ condition when testing begins, unless specific instructions as to any pre-test “conditioning“ are contained in the test request/order. For example, electrical terminals typically have residual die lubricant on them when finally assembled into a vehicle. This same co
48、ndition must prevail for test samples unless part cleaning is specified in the Test Request/Order. All material used in each test sample shall conform to the material specifications shown on the latest revision of the applicable part drawing(s). The material hardness specified for electrical termina
49、ls refers to the blank strip material and not the finished product because the terminal manufacturing process can modify the hardness values. 5.1.4 Temperature, Sealing, and Vibration 5.1.4.1 Temperature Performance Requirements The trailer tow interface is intended to operate in -40 to +85 C environmental conditions
