Product Code:SAE J722
Title:Power Take-Off Definitions and Terminology for Agricultural Tractors (Cancelled Mar 1991, Superseded by ASAE S205.2)
Issuing Committee:Agricultural Tractor Standards Committee (Atsc)
Scope: This SAE Recommended Practice deals only with the definitions and terminology pertaining to the power shafts of agricultural tractors in which the power take-off rotational speed is proportional to the engine speed. This is the type that prevails in the United States, Canada, England, and generally throughout the world. The following recommendations will facilitate a clear understanding for engineering discussions, comparisons, and the preparation of technical papers.

Product Code:SAE ARP1153
Title:Method for Determining Relative Specific Gravity Polytetrafluoroethylene Tubing
Issuing Committee:G-3, Aerospace Couplings, Fittings, Hose, Tubing Assemblies
Scope:This document describes a method for determining the specific gravity of tubing, fabricated from polytetrafluoroethylene, after a controlled heating and cooling cycle. The specific gravity obtained by this method is a measure of relative molecular weight of the resin. The measure, termed relative specific gravity (RSG), increases with decreasing molecular weight (see 2.3).【英文标准名称】:Safetyandcontroldevicesforgasburnersandgas-burningappliances-Particularrequirements-Part4:Valve-provingsystemsforautomaticshut-offvalves
