Step-by-step

Steps to obtain a certificate with the Kiwa Water Mark are:

    Fill in an application form and send it to Kiwa (application form is located on down below)
    Kiwa sends a quotation, which is at the same time a concept-agreement, drawn up according to the requirements of the guideline
    After mutual signing of the quotation, the agreement is definitive and the initial audit can start
    After positive results of the initial audit, the certificate will be issued
    The certificate is valid indefinitely
    A part of the agreement is periodic audits

Important aspects of the initial audit (steps 3 and 4) include:

a. Testing with regard to the product and/or performance requirements.
Testing, often carried out in our own laboratories, demonstrates that the product meets the certification requirements for functional and hygienic aspects, such as durability, dimensions, composition of materials, etc.;

b. Assessment of the production process, quality system and internal quality control (IQC) scheme.
To ascertain that the producer is continually able to manufacture products that meet the certification requirements.

The periodic audits aim at the maintenance of the management system, in order to maintain confidence that the producer is still able to manufacture products that meet the certification requirements. The periodic audits include functional and hygienic tests of the certified products.

The audit frequency varies from product group to product group: in general, 2 to 4 times per year.

Conditions for the certification process are stated in the Kiwa Regulations for Product Certification and the General Terms and Conditions of Kiwa for the performance of orders.
