Accreditations and certifications

Why use an accredited laboratory?

Accreditation is a system that creates more confidence in the services that an accredited company provides.

The company is continuously assessed in relation to an internationally recognized accreditation standard. In it, the requirements that must be met are stated. In order to obtain or maintain an accreditation, the company and the employees’ technical competencies as well as equipment must be approved.

When the company meets the requirements for being accredited, other companies, authorities and customers can have greater confidence that the quality on the part of the company will be as expected. The company is judged on the requirements that apply to this particular type of company.
