Product Code:SAE AMS2315
Title:Determination of Delta Ferrite Content
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers two methods for determining the percentage of delta ferrite in steels and other iron alloys.Product Code:SAE J2284/3
Title:High-Speed Can (Hsc) for Vehicle Applications At 500 Kbps
Issuing Committee:Vehicle Architecture For Data Communications Standards
Scope:This SAE Recommended Practice will define the Physical Layer and portions of the Data Link Layer of the ISO model for a 500 KBPS High-Speed CAN (HSC) protocol implementation. Both ECU and media design requirements for networks will be specified. Requirements will primarily address the CAN physical layer implementation.Requirements will focus on a minimum standard level of performance from the High-Speed CAN (HSC) implementation. All ECUs and media shall be designed to meet certain component level requirements in order to ensure the HSC implementation system level performance at 50 KBPS. The minimum performance level shall be specified by system level performance requirements or characteristics described in detail in Section 6 of this document.This document is designed such that if the Electronic Control Unit requirements defined in Section 6 are met, then the system level attributes should be obtainable.This document will address only requirements which may be tested at the ECU and media level. No requirements which apply to the testing of the HSC implementation as integrated into a vehicle are contained in this document. However, compliance with all ECU and media requirements will increase the possibility of communication compatibility between separately procured components and will greatly simplify the task of successfully integrating a HSC communication system in a vehicle.
