Various certification organizations may be i

Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “T oxi

21、cology Review and Evaluation Procedures,” to NSF/ANSI 61 does not stipulate a maximum allowable level (MAL) of a contaminant for substances not regu- lated by USEPA final maximum contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guid

ANSI/AWWA C561 does not address additives requirements. Thus, users of this standard should consult the appropriate state or local agency

23、having jurisdiction in order to 1. Determine additive requirements, including applicable standards. 2. Determine the status of certifications by parties offering to certify products for contact with, or treatment of, drinking water. 3. Determine current information on product certification. II. Spec

It is the responsibility of the user of an AWWA standard to determine that the products described in that standard are suitable for use in the particular application being considered. * NSF Internati
