To demonstrate that the product meets the requirements

Conformity assessment to demonstrate that a product or a service meets the requirements of the applicable regulations or standards is a key issue in the process of placing it on the market.


  • Provides consumers with a basis for selecting products and confidence in their features. 
  • Provides regulators with means to enforce national legislation and to achieve public goals like security. 
  • Assures manufacturers that their products meet regulations and the market access. Certification is the method to demonstrate the conformity of a product according to the requirements of the regulators or the market.

The most important elements in a product certification are: 


  • Testing to determine the relevant product characteristics. 
  • Auditing of the production process and/or quality system. 
  • Review of the test and auditing reports. 
  • Issue of the certificate. 
  • Surveillance by testing or inspectioon of product samples and the surveillance of the production process.

It is of paramount importance that these activities are carried out by a body that is competent, impartial, independent, responsible and reliable like the certification unit of ALTER TECHNOLOGY TÜV NORD.
