NSF tests and certifies home appliances to help demonstrate product efficacy and provide retailer and consumer confidence that the product will perform as claimed by the manufacturer.

NSF’s appliance testing and certification builds on NSF’s expertise in national standards and protocol development, testing and certification to help ensure the safety and quality of consumer products and home appliances.

Benefits of Certification

NSF tests home appliances to help manufacturers distinguish unique product features, and to provide consumers with confidence regarding their purchases. NSF leads the development of the testing criteria, which is based on peer-reviewed, scientifically tested, transparent testing protocols to validate product performance.

Appliances certified in this program bear the trusted NSF certification mark, a symbol to show products have been independently evaluated against a rigorous set of quality and requirements. It is also proof that the product claims featured in the standard (regarding sanitization, allergen reduction, etc.) have been verified by NSF International.

Benefits include:

  • Provides independent, third-party evaluation of products and validates product claims (such as sanitizing cycles or allergen reduction)
  • Can expedite buyer acceptance process
  • Provides brand protection

Protocols and Standards

NSF protocols and standards for home appliances were developed by our public health experts with input from key industry stakeholders including retailers, manufacturers, industry associations and regulatory agencies.

Current NSF standards and protocols for home appliances include:


  • NSF/ANSI 184: Residential Dishwashers


  • NSF P154: Sanitization Performance of Residential Clothes Dryers
  • NSF P172: Sanitization Performance of Residential and Commercial, Family-Sized Clothes Washers
  • NSF P205: Residential Food Processors
  • NSF P335: Hygienic Commercial Hand Dryers
  • NSF P351: Allergen Reduction Performance of Residential and Commercial, Family-Sized Clothes Washers

Why Work With NSF?

NSF’s testing and certification of home appliances builds on our unparalleled expertise in national standards and protocol development, testing and certification. We began development on the first standards for commercial foodservice equipment in 1944 and currently have 70 active standards and over 75 active protocols for a wide range of commercial and consumer products.

Our transparency in testing and test methodologies is unique. Other test labs simply test and report, but our testing process is dynamic, with valuable technical feedback that helps improve your product’s design and speeds time to market.

Once certification is granted, your company can use the NSF certification mark on packaging and in promotions. The mark tells consumers that the product has been independently tested and certified in one of world’s leading laboratories by health and safety experts.

Certification Process

NSF certifies products in five simple steps, led by a single point of contact with the technical expertise and dedication to expedite the process.

Step 1: Application — Your company submits an application for certification and receives a quotation based on factors including number of SKUs, special claims and production location.

Step 2: Product Submittal — NSF requests samples for evaluation and testing, along with key product information.

Step 3: Product Evaluation and Testing — Our engineers test/evaluate the product to ensure it meets all criteria.

Step 4: Manufacturing Facility Audit — An NSF auditor visits the production facility to confirm that all components of finished products are the same as those tested in our laboratories. This provides assurance of an effective, ongoing quality system.

Step 5: Certification Granted — Once the product evaluation is successfully completed and all criteria are met, your certification is granted and your product information is included in the online NSF product listings.
