Annotation of standard text ASTM F3238-17(2023) :
This specification prescribes the exposure limits and safe operating guidelines for infrared (IR) radiating devices to be mounted on N registered aircraft or any aircraft which is flown or operated in the United States or its territories. The American Conference of Governmental Industrial Hygienists (ACGIH) has established threshold limit values (TLVs) for IR radiation exposure. The TLVs represent a safe exposure limit without physical harm, even with daily exposure. For this specification, the safe exposure time has been set at 100 seconds to reach the TLV. Therefore, the safe operating distance is calculated by determining the maximum output radiation of the device such that 100 seconds of exposure does not exceed one TLV as established by ACGIH.
