The field of direct application defines the permissible variations that can be introduced to a tested specimen without requiring further testing or assessment. These modifications can be directly applied to tested systems and are generally considered conservative.
Note that this test was carried out with the fire on the side with the two layers of 12.5 mm Gyproc Fireline.
Please note that any number of these variations can be considered at the same time.
Height: the maximum permitted construction height is 3.04 m.
Wall thickness: the width of the construction can be increased without limitation.
Component thickness: the thickness of individual components may be increased.
Board and panel sizes: there may be a decrease in the linear dimensions of boards or panels, but not a decrease in thickness.
Stud spacing: the maximum stud spacing is 600 mm, but reduction in spacing is permitted.
Fixing centres: the distance between fixings may be reduced.
Horizontal joints: there may be an increase in the number of horizontal joints, of the type tested when tested with one joint not more than (500±150) mm from the top edge.
Vertical joints: there may be an increase in the number of vertical joints, of the type tested.
Any variations to the tested system beyond those outlined above could be considered as part of a technical fire assessment prepared in accordance with the PFPF Guidelines.
Our CPD covers the guidance, regulations and testing for insulation products. It takes a look at essential terminology for understanding how a fire develops and how products need to perform as a fire develops.
