2.Stages
The subsystem is checked at each of the following stages:
overall design,
production: construction of subsystem, including, in particular, civil-engineering activities, manufacturing, constituent assembly, overall adjustment,
final testing of the subsystem.
For the design stage (including the type tests) and for the production stage the applicant may apply for an assessment as a first step.
In this case, this assessment or assessments lead to one or more intermediate statement verifications (ISV) issued by the notified body chosen by the applicant. The notified body in turn draws up an ‘EC’ declaration of intermediate subsystem conformity for the relevant stages.
