What Manufacturers Need to Know About Electrical Safety Testing Certification for Refrigeration Equipment
Guidance on Electrical Safety Testing Certification for commercial refrigeration equipment manufactured for sale to the US market.

What is Electrical Safety Testing Certification and who is it for?
Before commercial kitchen and restaurant equipment can be sold for use in the US, it must comply with US electrical safety regulations. That means ensuring equipment has been tested and certified to meet two specific electrical safety standards set by the US Occupational Safety and Health Administration (OSHA).
The two OSHA standards that must be met are:
- 29 CFR 1910 Subpart S
- 29 CFR 1926 Subpart K.
These standards are designed to keep employees safe at work, protecting them from dangers such as electric shock, electrocution, fires and explosions.
They apply to any manufacturer, anywhere in the world, that is seeking to manufacture food service equipment for the US market.
Who can issue Electrical Safety Testing Certification?
Electrical Safety Testing Certification can be issued only by an OSHA-approved and qualified certification body such as NSF.
NSF has a global network of laboratories available to support manufacturers with a range of commercial refrigeration equipment, including:
- Commercial ice machines
- Commercial refrigerators
- Commercial freezers
- Commercial ice maker machines
- Commercial ice dispensers.
In addition to commercial refrigeration equipment, our global network can test and certify other electrical food equipment, including dishwashers and feeders, commercial cooking, and vending machines.
What are the benefits of Electrical Safety Testing Certification?
The U.S. food service market is currently worth over $1 trillion and is forecast to grow to over $2 trillion by 2032.1 For manufacturers of commercial refrigeration equipment it has the potential to be a highly lucrative market.
What other certifications are required before commercial refrigeration machinery can be sold into the US market?
In addition to Electrical Safety Testing Certification, any commercial or industrial food service equipment manufactured for use in US kitchens and restaurants will need Food Equipment Sanitation Safety Certification.
Plus, although not mandatory for all commercial kitchens and restaurants in the US, ENERGY STAR® certification is a requirement for manufacturers seeking to manufacture refrigeration and freezer appliances for federal, state, and local government purchasing contracts.
