Product Code:SAE ARP159
Title:Dielectric Testing of Spark Plugs
Issuing Committee:E-30 Propulsion Ignition Systems Committee
Scope:This report provides information on instrumentation and procedures for the dielectric testing of aircraft piston engine spark plugs to determine their functional condition. This report describes a method of determining the dielectric integrity of a spark plug by subjecting the insulation in the plug to voltage stress.Product Code:SAE J684
Title:Trailer Couplings, Hitches and Safety Chains - Automotive Type
Issuing Committee:Trailer Committee
Scope:This SAE Standard includes couplings, hitches, and safety chains used in conjunction with all types of trailers whose Gross Vehicle Weight Rating (GVWR) does not exceed 4540 kg (10,000 lb). This includes such types as utility, boat, camping, travel, and special purpose trailers which are normally towed by conventional passenger cars, light-duty commercial vehicles, light trucks, and multi-purpose passenger vehicles. This document is intended primarily for ball-and-socket type of couplings and hitches. It should not be construed as a limitation to this type alone but should apply where appropriate to ring-and-pintle, clevis-and-pin, or any other draft means designed to serve this purpose.
