SAE J2358_201009

This SAE Standard defines the safety and performance requirements for Low Speed Vehicles (“LSV”). The safety specifications in this document apply to any powered vehicle with a minimum of 4-wheels, a maximum level ground speed of more than 32 km/h (20 mph) but not more than 40 km/h (25 mph),), and a maximum gross vehicle weight of 1361 kg (3000 lb), that is intended for operating on designated roadways where permitted by law. The revisions to SAE J2358 are intended to achieve consistency with other SAE standards and procedures, to make the test results more repeatable and quantitative, and to incorporate improvements in test procedures and data analysis. The primary changes and the reasons for them are listed as follows: a Added the Table of Contents Reason: To make sections easier to access b Revised Scope to increase maximum G.V.W. to 1361 kg (3000 lb) Reason: To include appropriate vehicles. c Reviewed normative references and deleted those not used, revised references as necessary, had SAE J1718 Stabilized, and added references Reason: To insure applicability and to include new references. d Revised definitions of Accelerator (3.1), Brake Pedal (3.4), Charged Battery (3.7), Fuel System (3.15), Low Speed Vehicles (3.22), and Operator or Driver (3.24), and added definition of Key (3.21). Reason: Clarity. e Revised (6.2.1) General - Safety Signs to add on-vehicle and in Operator Manual information. Reason: To insure that required information will be included. f Revised (6.4) Operational Controls to define Reverse Warning Indicator (6.4.4.1) and to add Theft Protection (6.4.5) Reason: To clarify the intent of the standard. g Revised General Configuration (6.5) to include revised anthropometry (6.5.2), to revise seat restraint anchorage (6.5.5.2), and to detail the requirements of the Operator Protection Structure (6.5.5.3) including new Figures 1a and 1b. Reason: To eliminate reliance on the FMVSS for timely and applicable revisions and to clarify the test procedures. h Revised the Brake Systems test conditions (6.6.4.1.1.e) and Brake System fade (6.6.4.2.1) test. Reason: For clarity and to better define worst case conditions. i Revised Park Brake test (6.6.4.4.2) to specify applied loads Reason: To define the two loading conditions needed for testing. j Revised Containment (6.7.2) by adding Impact Containment (6.7.2.1) and Roll-over Containment (6.7.2.2) test conditions, test procedure, and test acceptance. Reason: To better define procedures and tests to allow accurate determination of test acceptance. k Revised Lighting (6.8) to better align requirements of Head Lamps (6.8.1 and 6.8.2), Tail Lamps (6.8.3), Stop Lamps (6.8.4), and Turn Signals (6.8.5), and add Center High Mounted Stop Lamps (6.8.4.2). Reason: To better align requirements with SAE Standards and FMVSS, and to also improve vehicle identification and recognition. l Revised Electric Powered Vehicles (7) Grounding (7.1.1) to add (7.1.1.a, .b, and .c) and EMC (7.2.3). Reason: To reflect current technology and safety practices, and to provide a procedure to ensure Electromagnetic Compatibility. m Revised Spark and Compression Ignition Engine Powered Vehicles (8) Fuel System Installation (8.3.2.1) requirements for over engine tanks, and added EMC (8.2.4). Reason: To reflect current technology and safety practices, and to provide a procedure to ensure Electromagnetic Compatibility. n Added Hybrid Vehicles (9) requirements Reason: To reflect current technology and safety practices.
