MIL-STD-1477B, MILITARY STANDARD: SYMBOLS FOR ARMY AIR DEFENSE SYSTEM DISPLAYS (30 SEP 1993)., This standard prescribes the physical characteristics of space, air, land, surface, and subsurface track symbols, and associated alphanumeric information, for US Army air defense displays which are generated by electronic, optic, or infrared technology and which presents information in real time or near-real time.
Product Code:SAE J2209
Title:CFC-12 (R-12) Refrigerant Recovery Equipment for Mobile Automotive Air-Conditioning Systems
Issuing Committee:Interior Climate Control Committee
Scope:The purpose of this SAE Standard is to provide equipment specifications for CFC-12 (R-12) recovery for return to a refrigerant reclamation facility that will process it to the appropriate ARI Standard (Air Conditioning and Refrigerant Institute) or allow for recycling of the recovered refrigerant in equipment that is certified to meet the requirements of SAE J1991. Under the existing rule, the U.S. EPA requires refrigerant removed from a mobile air-conditioning (A/C) system using recovery equipment certified to meet SAE J2209 can only be recycled using equipment meeting SAE J1991 that is owned by the same company or individual.It is not acceptable that the refrigerant removed from a mobile A/C system, with this equipment, be directly returned to a mobile A/C system.This information applies to equipment used to service automobiles, light trucks, and other vehicles with similar CFC-12 (R-12) systems.【英文标准名称】:Telecontrolequipmentandsystems-Part1:Generalconsiderations-Section4:BasicaspectsoftelecontroldatatransmissionandorganizationofstandardsIEC60870-5andIEC60870-6
