About Certification

What Is KC Certification (Hygiene Safety)?

KC Certification (Hygiene & Safety) is a legally required scheme under Article 14(1) of the Waterworks Act for waterworks materials and products that contact water in water facilities (excluding intake, storage, and conveyance facilities).

Application Documents
  • Certification application
  • ISO 9001 certificate (if held)
  • Material information sheet
  • Product grade / designation
  • Manufacturing & inspection equipment list
  • Business registration certificate
  • Product design drawings and water-contact ratio calculation basis
  • List of procedures (materials, process, product quality, manufacturing equipment, and inspection equipment control)

Audit Process

KC factory audit
01

Factory Audit

Two auditors from Korea Water Technology Certification (KWTC) score each factory-audit item as high, middle, or low.

A total of 80 points or more out of 100 is a factory-audit pass. Knowing scoring criteria in advance directly improves pass rates.

KC product audit - leaching test
02

Product Audit (Leaching Test)

After the factory pass, an accredited lab performs leaching tests per the official hygiene & safety test methods for waterworks materials and products. Final certification requires results that meet the criteria.
