Once your application is received, NSF will assign a program representative to your company. Your program representative will be your primary contact with NSF. Your representative will handle all of your needs and questions, overseeing your certification project every step of the way.
NSF applicants submit product information to NSF. This information may include: performance standards, product literature, pictures, schematic drawings, parts lists, trade names of materials, supplier names, intended end uses for the product, etc. Click here for downloadable forms.
This information helps NSF determine exactly what testing and/or toxicological services will be needed for the certification of your product.
If you have requested certification for your potable water plumbing products, NSF requires formulation disclosure for each wetted part. If need be, specific information will be requested from your suppliers.
If your product contains NSF-Certified materials, it may significantly reduce the amount of testing required to certify your product. Therefore, the use of NSF-Certified materials and components may save you time and money.
Initial Facility Inspection and Equipment Evaluation
An initial production facility inspection is required for the certification of all products not manufactured at listed production facilities.
An NSF field representative will make an appointment to visit your facility and explain the impact of the product's certification on the manufacturing facility. The field representative will review requirements such as: materials, quality assurance, record keeping, and product marking.
When completed, you will receive a detailed audit report documenting your facility's compliance with the appropriate NSF standards and policies, along with a written list of corrective actions, if any.
Your field representative will work with you closely to correct any issues that arise during the audit.
Product Sampled for Testing
NSF typically tests products against the following standards: ASME, ASSE, ASTM, AWWA, CSA, DIN, IAPMO, ISO, UL, and NSF.
When testing is required for product certification, your NSF field representative can take samples when your facility audit is performed, or your manufacturing facility may be asked to send the samples directly to the NSF testing lab location that will perform the tests.
NSF is also able to conduct testing at the manufacturing facility through the Witness Testing Program.
When the applicable information, audit, and testing requirements of NSF have been successfully applied to your product, you will be authorized to apply the NSF Certification Mark on your product.
Your product will immediately be included in the NSF electronic access database of Listed products, and will also be shown in the NSF Listings book, issued each year.
NSF has an established annual monitoring program in order to ensure that certified products continue to meet the requirements of the standards against which they are certified.
In addition to periodic product retesting outlined in the NSF policies, your manufacturing site will receive unannounced inspections by NSF field representatives each year.
During these inspections, the NSF representative will verify that your continued manufacture of the Listed product or material does not depart from your documented original formula/design. Typically, formulation verification, manufacturing process, and quality assurance records are reviewed. At the end of the audit, the auditor will provide you with a full report of the inspection, listing your compliance in each required area, or any necessary corrective actions.
Your NSF field representative will work with closely with you should any corrective action be required.
