The surveillance contract is, therefore, a different or separate contract from the DIT / DITplus issuing contract.
This contract is made to verify, among other things, that in the five years of validity of the DIT / DITplus, the compliance with the requirements established in the document is maintained. Thus, during the years following the issuing, annual audits are made to the factory to verify the Factory Production Control, to answer questions from users, manufacturer is informed about the modification of the regulations that may affect the DIT / DITplus, a surveillance is carried out -depending on the type of product- of works, and also small modifications or addenda can be included to the document if necessary, etc.
The certificates of compliance with the monitoring will be issued by the IETcc at the beginning of the year, during the four years following the year of granting the DIT / DITplus and provided that the planned surveillance has been carried out with a favourable result. The objective is that at the end of the validity of the DIT / DITplus, it can be renewed automatically.
