17 - SECTION 4 PURITY REQUIREMENTS OF REFRIGERANTS FOR USE IN AUTOMOTIVE AIRCONDITIONING SYSTEMS

Specifies the minimum equipment requirements for safe and efficient recovery or combined recovery and recycling of refrigerants directly removed from and intended for reuse in automotive air-conditioning systems. It specifies test methods to determine equipment performance and minimum purity levels allowed for recycled R12 and R134a refrigerants. This Standard applies to equipment used to service cars, trucks and other vehicles with similar air-conditioning systems. Equipment used on mobile vehicles that have hermetically sealed systems for refrigerated cargo are not covered in this document.
