Presentation of characterisation data and their field of application
for products and systems for protecting elements or parts of work

The classification document is drafted as described in A.2, except for f), g) (iii) and j).

6. Specification of the standard vertical structural members tested:

• steel test columns;

• concrete test columns;

• concrete filled hollow steel test columns;

• timber test columns;

• aluminium test columns;

6. (iii) presentation of data;

A graph is given of all relevant individual and mean temperature readings, as defined in the test standard, and used for classification and extension of test results.

10. presentation of characterisation data;.

The characterisation data for vertical protection membranes are presented as shown in Table B.1.

Table B.1 is based on the reference temperature curves as specified in the relevant test standard.
