Product Code:SAE J1503
Title:Performance Test for Air-Conditioned, Heated, and Ventilated off-Road self-Propelled Work Machines
Issuing Committee:Hftc6, Operator Accommodation
Scope:This SAE Recommended Practice outlines a test procedure for off-road, self-propelled work machines providing a uniform measurement of operator environmental temperature and humidity provided by a complete air handling system operating in a specified ambient environment; and establishes minimum performance levels for the operator enclosure's heater, ventilation, and air conditioning system. This SAE Recommended Practice applies to off-road, self-propelled work machines used in construction, general-purpose industrial, agricultural, forestry, and specialized mining machinery as defined in SAE J1116, and establishes the following minimum performance levels in the operator's environment for the seated position. Minimum operator enclosure pressurization and ventilation levels in the operator's environment for the seat position. Maximum humidity and minimum temperature differential under air conditioning operation. Minimum temperature differential under heater operation.【英文标准名称】:Textiles.Methodoftestforwovenfabricsforclothingandforclothing.Methodforassessmentofslippageofyarninawovenfabricandmeasurementofslippageofsemas.
