Buyer beware-are you?

By Ward Atkinson, MACS Technical Adviser

Many years ago, when vehicle manufacturers advertised the horsepower of their engines, the information could not be compared between manufacturers because they didn’t all measure horsepower the same way. Through the efforts of SAE International and its committee members, SAE Standard J2723 — “Engine Power Test Code: Engine Power and Torque Certification,” was developed to govern the actual measurement of engine power. This Standard allows direct comparison of each manufacturer’s SAE-certified engine horsepower and torque information.

In a similar manner, people working in the mobile air conditioning industry have encountered many products with a label that says it “meets or exceeds” SAE Standard requirements. Until recently, there was no way to independently verify that statement. In 2011, the SAE Interior Climate Control Standards Committee developed and published SAE J2911 — “Procedure for Certifying compliance with SAE Standards.”

The purpose of SAE J2911 is to provide a paper trail, so a customer or a regulatory agency can see that the product has been properly tested and delivers the performance spelled out in the SAE standards to which it is certified. After a company submits their lab test data and all other required information to SAE International, a J2911 certification is issued and posted on the SAE website. Only then can a company claiming compliance for their product advertise that their product does indeed meet the SAE performance standard, and only then can they make that claim on their product or packaging. Those products include mobile air conditioning system components, service equipment and service training.

Products meeting the J2911 requirements can be found at This website provides a public listing of the product, searchable by several different criteria. Clicking the MMR number in the upper right corner of the search result leads to the company’s J2911 registration. There’s also a link to a description of the performance standard the product must meet. And in the interest of industry self-regulation, there’s also a link where companies, regulators or individuals can challenge a product’s compliance with the SAE performance standard. The right-hand column of the page has a list of SAE Standards referenced by J2911 and links to descriptions of each Standard.


Here’s a sample of some of the certified products and suppliers currently posted on the SAE website. These companies have completed their J2911 Certification and may claim their product meets SAE performance standards in their advertising. Search for any of these names to test-drive the website and learn more.
