General building approval Z-78.4-51 for smoke protection dampers of the type JZ-RS
10/20/2006
The duration of validity has been extended to 27th July 2011.
The scope of the approval is smaller than in older approvals. For example, there are no longer any parts lists or drawings of individual parts. This makes the approval more friendly towards the applicant and easier to keep track of.
Detailed specifications on inspection and maintenance activities are no longer part of the approval.
For further information see the general building approval Z-78.4-51.
