Faucet Certification Marks
A faucet that is tested and certified will be marked by the certifying organization. Unfortunately, there are a number of such organizations, and the certification marks nor only vary but are usually cryptic references to a bunch of logos, letters and numbers that make sense only to industry professionals.
To de-mystify the marks and their meanings, here is a list of the most common certifying organizations and an explanation of what their marks mean.
Marks indicating certification are required to be permanently marked on the faucet itself, "located in such a way that they are visible after installation".
Compliance with ASME A112.19.1
|International Association of Plumbing and Mechanical Officials. The UPC Shield is applied to faucets that are certified by IAPMO as complying with ASME A112.18.1/CSA B 125. The "C" under the shield indicates that the faucet complies with both the U.S. and Canadian standards for faucets.|
|International Codes Council - Evaluation Service. The ICC-ES mark is applied to faucets that are certified by ICC-ES as complying with ASME A112.18.1/CSA B 125. The optional "C" indicates that the faucet complies with both the U.S. and Canadian standards for faucets.|
|Canadian Standards Association. A (CSA) mark signifies that a faucet complies with ASME A112.18.1/CSA B 125. The optional "US" or "NRTL" means that the faucet is meets the applicable U.S. standards. A CSA mark with the indicators "C" and "US" or "NRTL/C" means that the product meets both U.S. and Canadian standards.|
|Intertek Testing Services NA, Inc., Intertek is an international testing service operating in 100 countries that tests to North American faucet standards, but also to other standards. The "C" or "US" mark must be present to indicate certification to ASME A112.18.1/CSA B 125.|
|NSF International. The basic NSF International certification mark must include a "C" or "US" or both, or a notation such as "U.P.Code" or "I.P.Code" to indicated compliance with ASME A112.18.1/CSA B 125. If the faucet has been certified only under the lead-free standard, one of the notations in the bottom row will be shown and an additional mark indicating compliance with ASME A112.18.1/CSA B 125 must also be present.|
|Underwriters Laboratories. Faucets displaying the (UL) mark have been evaluated and found to comply with all applicable nationally recognized health effect and performance standards, and have demonstrated compliance with both the IPC and UPC plumbing codes. The notations "CA", "US" or "CA & US" may be shown to indicate compliance with Canadian and/or U.S. standards.|
|Water Quality Association. The WQA mark indicates faucet compliance with ASME A112.18.1 and NSF 61. The mark will usually be accompanied by a notation indicating with which standard the faucet complies, as "ASME A112.18.1/CSA B 125" or "NSF/ANSI 61".|
Lead Free Compliance Marks
In addition to certification of compliance with the composition, safety and mechanical function requirements of ASME A112.18.1/CSA B 125, a faucet must be "lead free" as that term is defined in the federal Safe Drinking Water Act. California, Maryland and Vermont have their own state-wide low-lead requirements. The low-lead standards are similar, but not the same, and efforts are being made to "harmonize" the standards so faucet companies can avoid unnecessary multiple certifications for low lead compliance.
Compliance with State Law
Prior to January, 2014 the national maximum for lead in faucets was 8%, and only California, Maryland and Vermont required the lower 0.25% limit.
At left are common notations used to show compliance with the state low lead standards.
Additional/Optional Certification Marks.
In addition to one of the required certification marks identified above, a faucet may also be certified in one or more of the following categories.
|CalGreen refers to the California Green Building Standards Code. Faucets that meet The CalGreen faucet standards have a maximum flow rate of 1.8 gallons per minute (for kitchen faucets) and 1.5 gallons per minute (for lavatory faucets), below the industry standard ASME A112.18.1/CSA B125.1 of 2.2 gallons per minute.|
