Three Test Standards Revised or Reaffirmed in January

January 19th, 2006

Three SAE test standards were either revised or reaffirmed in December 2005:

• J1621 DEC2005 (Reaffirmed) Engine Retarder Dynamometer Test and Capability Rating Procedure. Issued by the Truck And Bus Engine And Vehicle Performance Subcommittee, this Recommended Practice specifies:
  • a basis for net engine retarder power rating;
  • reference inlet air test conditions;
  • a method for correcting observed engine retarder power to reference conditions; and
  • a method for determining net engine retarder power with a dynamometer.
• J1742 DEC2005 (Revised) Connections for High Voltage On-Board Road Vehicle Electrical Wiring Harnesses—Test Methods and General Performance Requirements. Issued by the Electrical Distribution Systems Standards Committee, this Recommended practice defines recommended test methods and general performance requirements of single-pole and multi-pole connectors for on-board electrical wiring harnesses of electric or hybrid powered road vehicles operating at voltages between 50 and 600 V AC or DC rms and those circuits using copper wire only.these requireemnts are not intended for connections internal to electrical/electronic modules or complete subassemblies.this document applies to connectors designed to be disconnected in the case of repair and/or maintenance after mounting in the vehicle.This document excludes onoe-part connections, i.e., where one part of the connection has direct contact to the pattern of the circuit board.Duty cycles are considered to be application specific and are not specified in this document; however, these effects must be considered during design.The Recommended Practice for Highvoltage Wiring Assembly is contained in SAE J1673. The Recommended practice for Low Voltage Connector Performance is contained in SAE J2223 (Parts 1, 2, 3, and 4).
• J2052 DEC2005 (Reaffirmed) Test Device Head Contact Duration Analysis. Issued by the Safety Test Instrumentation Stds Committee, this methodology can be used for all calculations of HIC, with all test devices having an upper neck triaxial load cell mounted rigidly to the head, and head triaxial accelerometers.
