Product Code:SAE J1542
Title:Laboratory Testing of Vehicle and Industrial Heat Exchangers for Thermal Cycle Durability
Issuing Committee:Cooling Systems Standards Committee
Scope:This SAE Recommended Practice is applicable to all liquid-to-air, liquid-to-liquid, air-to-liquid, and air-to-air heat exchangers used in vehicle and industrial cooling systems. This document outlines the tests to determine durability characteristics of the heat exchanger under thermal cycling.This document is to provide a test guideline for determining the durability of a heat exchanger under thermal cycle conditions.Product Code:SAE AS681
Title:Gas Turbine Engine Steady-State and Transient Performance Presentation for Digital Computer Programs
Issuing Committee:S-15 Gas Turbine Perf Simulation Nomenclature And Interfaces
Scope: This Aerospace Standard (AS) provides a method for the presentation of gas turbine engine steady-state and/or transient performance as calculated by means of digital computer programs. It also provides a method for the presentation of gas turbine parametric performance, weight and dimensions by means of digital computer programs. It is intended to facilitate calculations by the program user without unduly restricting the method of calculation used by the program supplier.
