Composting Toilet Certification Claims

We thought we would discuss briefly the topic of certifications and composting toilets in order to clarify a few things. We have received emails regarding some possibly confusing issues and hope to dispel any myths.

Questions about NSF® Standard-41
NSF® Standard-41 is a common standard looked for by many local and state authorities in the United States. This is a composting toilet system performance standard.

On the web, you may find that some composting toilet companies claim that only NSF® can test to an NSF® standard, such as NSF® Standard-41.

Is this true? Can only NSF® test to NSF® Standard-41?
No, this is not true. Although NSF® (National Sanitation Foundation) created Standard-41, other Nationally Recognized Testing Laboratories (NRTL) can test to the same standard. Among other reasons, this allows for fair competition by allowing companies to get local testing agencies to test their products.

Any company that tells you or advertises this is either incorrect and/or misleading you.

For example, Envirolet® Composting Toilet Systems were tested and are certified to meet NSF® Standard-41 and ANSI/NSF-41 1998 by CSA®, the Canadian Standards Association.

CSA® tests and certifies products to a wide range of regional, national and international standards, including standards written or administered by the American National Standards Institute (ANSI), Underwriters Laboratories (UL), Canadian Standards Association (CSA), National Sanitation Foundation (NSF), International Electrotechnical Commission (IEC), and others. [Via CSA®.]

If you have any concerns or questions about this, please contact CSA® on the web or by calling 1-866-797-4272.

What about claims of being the only certified or listed product?
A product certified to an NSF® standard by another agency (e.g., CSA®, UL®) will not appear on the NSF® web site. But, will appear on the actual testing agency web site and/or a copy of the certification will be available from them upon request.

What about claims of being the first certified or listed product?
Again, this may be true. But, in reality, this is irrelevant. The first microwave oven certified many many years ago to a standard is not necessarily better than one certified last week.

Composting Toilet World is in favour of standards for composting toilets. We want quality products for consumers so the use of composting toilets will spread! We do not believe certifications should be used as a marketing tool. Standards for electrical components for safety are the most important to look for.

Please contact Composting Toilet World if you have any questions or comments about certifications.
