KIWA Certification

KIWA Certification

In Benelux KIWA is the highest certification authority in the area of drinking water and environmental products. Furthermore, KIWA is the only institution to set up demands for certification of products for water sampling – including uncoloured PE pipes/ filters as well as PVC pipes/ filters free of heavy metals.

The result of producing KIWA certified uncoloured PE

Twice each year the Rotek production facilities are being audited. The following issues are investigated:

  1. The presence of certificates for each purchased batch of KIWA approved raw materials.
  2. That all raw materials used are approved by KIWA for production of the certified pipes.
  3. That all control reports are satisfactory – including a check that the marking of batch number and pipe number on each produced pipe are consecutive and traceable (raw material batch nr., time of production, size of product batch etc.)
  4. That all error reports regarding ovality, thread, slots etc. are satisfactory
  5. That all product batches have been tested with a mandrel.
  6. That samples have been taken from each product batch.
  7. The risk of contaminating the products with oil or other contaminants from the production area.
  8. That the production area is clean and orderly.
  9. To verify that pipes for water sampling solely consist of carbon and hydrogen a sample of the produced pipes are taken. This samples is sent to a laboratory to be tested for the presence of the following components:

 

Metals Chlorinated hydrocarbons Mineral oil Volatile chlorobenzenes
Arsenic Dichloromethane Hydrocarbon fraction C10-C40 Monochlorobenzene 
Cadmium Chloroform Hydrocarbon fraction C10-C12 1,3-Dichlorobenzene
Chromium Tetrachloromethane Hydrocarbon fraction C12-C16 1,4-Dichlorobenzene
Cobolt Trichloroethene Hydrocarbon fraction C16-C20 1,2-Dichlorobenzene
Copper Tetrachloroethene Hydrocarbon fraction C20-C24 1,3,5-Trichlorobenzene
Lead 1,1,1-Trichloroethane Hydrocarbon fraction C24-C28 1,2,4-Trichlorobenzene
Mercury 1,1,2-Trichloroethane Hydrocarbon fraction C28-C32 1,2,3-Trichlorobenzene
Nickel 1,1-Dichloroethane Hydrocarbon fraction C32-C36 Sum Dichlorobenzenes
Zinc 1,2-Dichloroethane Hydrocarbon fraction C36-C40 Sum Trichlorobenzenes
  1,2-Dichlororethene (cis)    
  1,2-Dichloroethene   (trans)    
  Sum 1,2-Dichlorethenes    

This means that KIWA is your guarantee for a reliable water sample!
