Tasks under the responsibility of the manufacturer |
Factory product control (FPC) |
Parameters related to essential characteristics of Table ZA.1.1 to ZA.1.4, which have to be declared fort he relevant intended uses |
Tasks under the responsibility of the notified body |
Initial type testing by a notified test laboratory |
Essential characteristics of Tables ZA.1.1to ZA.1.4, which have to be declared for thr relevant intended uses |
Tests Required to be Performed by Notified Laboratories: For initial type tests, the control activities of the certification body for products included in system 3 are limited to the following features. The producer is responsible for the application of other tests given in the ZA.1 table.
1) Reaction to fire,
2) Bond strength,
3) Durability of bond strength against climate/ heat ageing action,
4) Durability of bond strength against water/humidity action,
5) Durability of bond strength against freeze-thaw cycles
