Certification for Motor-Compressors
UL helps manufacturers introduce safe designs to the US and Canadian markets through certification to UL 60335-2-34, the Standard for Household and Similar Electrical Appliances, Part 2: Particular Requirements for Motor-Compressors and CSA C22.2 No. 140.3, the Standard for Hermetic Refrigerant Motor-Compressors.
One test, global access
Since UL 60335-2-34 is an IEC based standard, UL can easily provide compressor manufacturers with a CB Report through a single, integrated test program in conjunction with the UL and cUL certification project.
UL is an accredited National Certification Body (NCB) in IEC 60335-2-34 and UL professionals are experts in project management of CB Scheme evaluations. Since regulations and certification requirements are ever-changing, UL can help you to obtain the necessary country certifications by:
- Identifying the critical standards and requirements needed to enter your target markets
- Completing all necessary forms and applications in the appropriate languages
- Coordinating management of sample submittals
- Paying submittal fees in appropriate currencies
- Obtaining authorization for product certification marks or certificates
Complete coverage
UL can also provide certification for remanufactured hermetic refrigerant motor compressors and remanufactured open type refrigerant compressors, as well as hermetic refrigerant motor compressors for hazardous (classified) locations. The applicable North America certification categories are as follows:
- Hermetic Refrigerant Motor-Compressors (SLIS2/SLIS8)
- Hermetic Refrigerant Compressor Motor Parts (SLLX2/SLLX8)
- Hermetic Refrigerant Compressor Motor Parts, Remanufactured (SLNU2/SLNU8)
- Hermetic Refrigerant Motor-Compressors, Remanufactured (SLLG2/SLLG8)
- Hermetic Refrigerant Motor-Compressors for Use in Hazardous Locations (MPAH2)
