Avikote WB1200 1. This approval relates to the use of Avikote WB1200 for the fire protection of I-shaped
steel sections, hollow steel sections and solid steel rods. The precise scope is given in Tables 1 to 4I which show the total dry film thickness of Avikote WB1200 (excluding primer and top sealer) required to provide fire resistance periods in accordance with BS476: Part 21: 1987. The scope includes periods of fire resistance of 30 minutes up to 120 minutes for differing I-sections, hollow sections and section factors (A/V), and for periods of fire resistance of 30 minutes up to 120 minutes for solid steel rods with differing section factors (A/V) and design temperatures in the range 350
oC to 750
oC.
2. This certification is designed to demonstrate compliance of the product or system
specifically with Approved Document B (England and Wales), Section D 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: 2000. 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 are applicable to steel sections blast cleaned to Swedish Standard
Sa 2.5 or equivalent and primed with a suitable and compatible primer. Specifications of surface preparations, primers and top sealers is available from Arabian Vermiculite Industries whose responsibility is to ensure that Avikote WB1200 is compatible for use in respect of both ambient and fire conditions. The total dry film thickness of primer should not exceed 0.1mm.
6. The data shown is applicable to Avikote WB1200 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 on going 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.
