Steelmaster 1200WF 1. This approval relates to the use of Steelmaster 1200WF for the fire protection of
I-shaped and hollow steel sections. The precise scope is given in Tables 1 to 20 which show the total dry film thickness of Steelmaster 1200WF (excluding primer and topcoat) required to provide fire resistance periods in accordance with BS476: Part 21: 1987 of 30 minutes up to 180 minutes for differing sections and section factors.
2. This certification is designed to demonstrate compliance of the product or system
specifically with Approved Document B (England and Wales), Section 2 of the Technical Standards (Scotland), Technical Booklet E (N. Ireland). If compliance is required to other regulatory or guidance documents there may be additional considerations or conflict to be taken into account.’
3. The products are approved on the basis of:
i) Initial type testing. ii) A design appraisal against TS15. iii) Certification of quality management system to ISO 9001: 2008.
iv) Inspection and surveillance of factory production control v) Audit testing
4. The data referring to three-sided fire exposure of beams relate to beams supporting
concrete floor slabs. Separate consideration is required where this is not the case. 5. The data shown is applicable to steel sections blast cleaned to Swedish Standard SA2.5
or equivalent and primed with a suitable and compatible primer. Specifications of surface preparations, primers and topcoats is available from Jotun Paints whose responsibility is to ensure that Steelmaster 1200WF is compatible for use in respect of both ambient and fire conditions. The total dry film thickness of primer and topcoat should not exceed that tested.
6. The data shown is applicable to Steelmaster 1200WF applied by spray to horizontal,
vertical, flexural and compression members supporting loads up to the maximum design loads specified in BS449: Part 2.
7. The approval relates to ongoing production. Product and/or its immediate packaging is
identified with the manufacturers’ name, the product name or number, the CERTIFIRE name or name and mark, together with the CERTIFIRE certificate number and application where appropriate.
8. The data shown in the tables is based on assessments which comply with the criteria for
acceptability now incorporated within the CERTIFIRE scheme.
