This SAE Standard provides testing and functional requirements to meet specified minimum performance criteria for electronic probe-type leak detectors. The equipment specified here will identify smaller refrigerant leaks when servicing motor vehicle air conditioning systems@ including those engineered with improved sealing and smaller refrigerant charges to address environmental concerns and increase system efficiency. This document does not address any safety issues concerning the equipment design or use beyond that of sampling a flammable refrigerant save those described in 3.1 and 3.2 of this document. All requirements of this standard shall be verified in SAE J2911 Purpose The purpose of this SAE Standard is to establish minimum performance criteria for a modern class of electronic probe- type leak detectors intended for use in automotive air conditioning systems with R-1234yf@ an A2L flammable refrigerant Grace Period This revision is subject to a 0 day grace period from the date of publication. After the grace period@ only the most recent version of this standard may be used for certification and/or recertification. To certify equipment to the prior version of this standard@ actual laboratory testing@ not merely the signing of a contract@ etc. must have begun prior to the publication date of this new version. No laboratory certification to any prior version of this standard@ shall be accepted by SAE for listing under the provisions of J2911 after 90 days from the publication date of this revision
