Certification System and Types of Certificates

Certification System and Programs

The PEHLA Certification system consists of four certification programs:

  • Type A program: Type testing (without monitoring),
  • Type B program: Type and routine testing (without monitoring),
  • Type C program: Design, type and routine testing, manufacturing/construction (with-out monitoring),
  • Type D program: Design, type and routine testing, manufacturing/construction (with monitoring),

which certify the conformity of the product to the standards in accordance with the specified reference standards to varying degrees [Table 1].

 

The Type A program confirms the conformity of the type tests at the time they are performed. This concerns:

  • the design values listed in the certificate, and verified,
  • the completeness and conformity of the type tests
  • the identity and consistency of the type test objects.

The Type A Certificate of Conformity does not apply to products of the same type or design which are manufactured subsequently. This proof is still the manufacturers’ responsibility in the form of their conformity confirmation for their customers ("Declaration of Conformity" accord-ing to ISO/IEC 17050-1, as First-Party Conformity Assessment).
The validity period of the Type A product certificate is not limited in this sense.

 

In addition to Type A, the Type B program also confirms the conformity of the routine tests for the product at the time the certificate is issued.
The validity period of the Type B Certificate of Conformity is not limited in this sense.

 

In addition to Type B, the Type C program also confirms the conformity of the product with re-gard to the product standards’ requirements regarding design (development) and construction (production).
The validity period of the Type C Product Certificate is not limited in this sense.

 

In addition to Type C, the Type D program also confirms the validity of conformity with regard to all conformity features for the current product, i.e. also for products of the same type manufac-tured subsequently, via monitoring by PEHLA ZERT.
The validity period of the Type D Product Certificate is 5 years.
