Special treatment chemicals are often used to safeguard the quality of the water in swimming pools and hot tubs. These products must of course not lead to health risks. Manufacturers who want to demonstrate that their swimming pool chemicals have been tested and meet strict requirements can request a product certificate from Kiwa according to NSF/ANSI/CAN 50 'Equipment and chemicals for swimming pools, spas, hot tubs and other recreational water facilities'.

Product certification to this standard may be required by the Model Aquatic Health Code and most US and Canadian state and local swimming pool codes. The use of pool chemicals certified against NSF/ANSI/CAN 50 guarantees that these products will not lead to contaminants and other residues in the treated water, with potential health risks if people ingest these substances through the mouth, skin or respiratory tract.

Annual tests and inspections

All NSF/ANSI/CAN 50 certified chemicals are under control. Annual testing and inspections ensure the continuous consistency of the required quality level. To maintain the certificate, producers may not change suppliers or make changes to product compositions without assessment and approval by Kiwa.

Accredited by ANSI

Kiwa can supply an NSF/ANSI/CAN 50 certification mark to identify approved products. Kiwa is ISO/IEC 17065 accredited by the ANSI National Accreditation Board (ANAB). Our accreditation status and accreditation scope can be consulted on ANSI accreditation Kiwa Nederland.
