    13、 specification have been verified and documented. All required verification and documentation must be done by the supplier of the part or parts. If testing is performed by another source, it does not relieve the primary supplier of responsibility for documentation of all test results and for verific

    14、ation that all samples tested met all applicable Acceptance Criteria. See section 4.3. 1 SCOPE Procedures included within this specification are intended to cover performance testing at all phases of development, production, and field analysis of any USB cable assemblies and associated connections t

    15、hat constitute the electrical connection systems between the consumer peripheral interface and the USB computer source in road vehicle applications. These procedures are only applicable to the USB connector and the cable. Unless otherwise specified, all of the tests listed in this specification are

    16、for both consumer and nonconsumer interface connectors. IMPORTANT NOTICE: All suppliers developing an automotive grade USB system must use components that have been validated and approved by an authorized USB testing facility per USB 2.0. In any intended vehicle application, if the products covered

    17、by this specification are, or may be, subjected to conditions beyond those described in this document, they must pass special tests simulating the actual conditions to be encountered before they can be considered acceptable for actual vehicle application. Products certified by their supplier as havi

    18、ng passed specific applicable portions of this specification are not to be used in applications where conditions may exceed those for which the product has been satisfactorily tested. The high frequency test methods are written for test professionals who are knowledgeable in the electronics field an

    19、d are trained to use the referenced equipment. Because the measurement values are heavily influenced by the fixturing and equipment this method cannot describe all of the possible combinations. The major equipment manufacturers provide Application Notes for more in-depth technical description of how

    20、 to optimize the use of their equipment. The Authorized Person is the final authority as to what tests are to be performed on his or her parts and for what purpose these tests are required. He or she is also the final authority for resolving any questions related to testing to this specification and

    21、 to authorizing any deviations to the equipment or procedures contained in this specification. Any such deviation must be documented and included in the final test report. Guidance as to the recommended tests for selected purposes is given in the charts in Appendix C. In the absence of contrary dire

    22、ction from the Authorized Person in the test request/order, all electrical connectors and their associated terminals and other components are required to meet all applicable portions of this document with the following exception: SAE/USCAR-30 PERFORMANCE SPECIFICATION FOR AUTOMOTIVE UNIVERSAL SERIAL

    23、 BUS (USB) CONNECTION SYSTEM Issued 2006-11 - 4 - Specific tests that are not required or additional test requirements as specified in any document in the hierarchy of Section 3.1. All suppliers of USB automotive assemblies must use certified USB 2.0 components (ie. USB mini-B receptacle, standard A

    24、 stainless steel receptacle or equivalent ruggedized receptacle, mini B plug). For non-consumer interfaces, please refer to the USCAR footprint drawing labeled 999-U-USB-Z01.pdf. The drawing can be found at www.ewcap.uscarteams.org Refer to USB 2.0 website (www.usb.org) for approved supplier list 2

    25、OUTLINE & GLOSSARY OF TERMS 2.1 GENERAL Diagrams are provided where necessary to clarify the details of the various test procedures. The tests in each section must be performed in the order given unless otherwise specified in the test request/order. Construction details for selected test fixtures an

    26、d equipment are provided in this specification. A glossary of terms is provided in Appendix B. Terms defined in the definitions or glossary are capitalized (i.e. Room Temperature, Steady State, etc.).

    32、Tests The laboratory test request/order shall provide location and documentation of test samples, identify the type of test to be performed (development, validation, special purpose, etc.) and describe any special tests that are not a part of this specification. Any required revisions to, or deviati

    33、ons from any tests in this specification must include detailed instructions for each change. 3.4.2 Test Request/Order Instructions Instructions must be included in the test request/order concerning applicable tests and the order in which the tests are to be performed if different than outlined by th
