How Does the Process for Certifying Your Materials Work?
If you are interested in certifying a specific material with NSF, that material must be sent directly to NSF labs for rigorous testing. The NSF will test the material within the qualifications to meet the specifications outlined in both NSF/ANSI 51 & 61. If the material passes those tests, you can pay the required fee and officially state that your specific material is NSF 51 & 61 certified. As long as you recertify the material with the NSF on an annual basis, you can market your material with the trusted and respected NSF stamp of approval. With your certified material, North Coast Seal can make anything that your operation can process—from O-rings to custom molded parts and more. North Coast Seal can also use our NSF 51 & 61 dual-certified rubber compound for your molding and sealing product needs.
