Performance at elevated temperature
Information required (intumescent manufacturer):
1. A report (hard copy) of the warringtonfire or BRE assessment of the thermal performance of the product as evaluated in the ASFP/SCI testing and assessment protocol.
2. The report must cover each required period of fire resistance.
Note: The protocol will be formally published in ‘Fire protection for structural steel in buildings’ 4th edition. Under the protocol, all testing must be carried out at either warringtonfire or BRE, both of which are NAMAS approved.
3. A report (hard copy) of the warringtonfire or BRE multi-temperature assessment of the product. This report must contain information of the variation of protection thickness with limiting steel temperature.
Note: This information is derived from the normal product assessment which might be reproduced in ‘Fire protection for structural steel in buildings’. It does not directly apply to cellular beams. This information is not processed by SCI but simply reproduced (for information) in the final SCI report.
Development of the thermal and mechanical model used to produce tables of limiting temperatures.
Development process (SCI)
4. For any intumescent coating and for each fire resistance period, the web post temperature relationship given in the protocol assessment report will be entered into SCI’s limiting temperature software.
5. Product-specific and fire resistance specific limiting temperature tables will be produced.
6. A SCI technical report including tables of limiting temperature and multi-temperature assessment will be issued to the client.
Administrative issues (SCI)
1. The SCI report will be stored electronically in the corporate archive. A hard copy will be retained in store by the SCI library. The reports received will be scanned and the electronic files stored with the hard copy report.
2. The software used to generate limiting temperature tables has been subject to a formal Quality Assurance process. This QA covered the generation of generic tables and product specific tables. The QA report on the limiting temperature software will be scanned and stored.
3. The software source code will be stored in SCI’s Microsoft SourceSafe database.
4. The mechanical and thermal models were developed in 2003 and reported in RT983. Details of the latest versions of both models are reported in RT1085, which is publicly available.
