Isotc92sc1 San Antonio e

Meeting: ISO/TC92(Fire safety) / SC1(Fire Initiation and Growth) and its working group meetings date: from 14 to 17 November, 2005 Venue: South-west Research Institute, San Antonio, Texas, USA Major contributions to the meeting Participation from NMRI 1. ISO/TC92/SC1 Chairman Koichi Yoshida Yoshida has been the Chairman of ISO/TC92/SC1 since Principal Research Coordinator 2004, and chaired this SC1 meeting. Eight P-members of ISO/TC92/SC1 met with 22 delegations. 2. ISO/TC92/SC1 work programme ISO/TC92/SC1 has been developing various ISO standards relating to fire safety, which relate to fire initiation and growth concerning products, materials, systems and components of building, transportation sectors (ships and offshore structures, train cars, land vehicles and airplanes) and other constructions. These standards have given possibilities of fire safety evaluation and assessment of these constructions, as mentioned as Fire Safety Engineering (FSE). Yoshida summarized the activities and standards of ISO/TC92/SC1 as in figure left. ISO/TC92/SC1 meeting in San Antonio ISO/TC92/SC1 Field of work

Do we need more guidelines for establishing fire scenario (fire growth, travel of fire effluences, etc.) ? Fire scenario (Building, Vehicle, Industrial construction, etc) (Specific products/material, such as façade, pipe insulation, sandwich panel, cables, etc.) 13784 13785 20632 22269

ISO/TC92/SC1 has the following working groups and a task group: WG3: Spread of flame tests WG5: Rate of heat release tests WG7: Large and intermediate scale fire tests WG10: Calibration of heat flux meters WG11: Applicability of reaction to fire tests to FSE WG12: Measurement of smoke gas components TG8: Uncertainty of measurements IMO (International Maritime Organization) has been using, in its mandatory and non mandatory instruments, various ISO standards developed by ISO/TC92/SC1 such as ISO 1182, 1716, 5658-2, 5660-1, 9705. ISO DIS 21489 is being developed under the demand of IMO.

3. Standard development Yoshida provided, as the project leader or co-leader, the following standards: ISO TS 17431: Fire tests - Reduced scale model box test ISO FDIS 14934-3: Fire tests - Calibration of heat flux meter - Part 3: Secondary calibration ISO TS 14934-4: Calibration of heat flux meters - part 4: Guidance on the use of heat flux meters in fire tests ISO DIS 21489: Fire- tests - Method of measurements gases using FTIR in cumulative smoke test In addition, following standards are also in the process of development in ISO/TC92/SC1: ISO TS 5658-1: Guidance on flame spread (revision) ISO 5658-2: Lateral spread on building products in vertical configuration (revision) ISO 14697: Guidance on the choice of substrates for fire tests ISO 5660-4: Measuring heat release for determination of low level combustibility ISO TS 22269: Full-scale stairs test ISO 20632: Room test for pipe insulation ISO 24473: Open calorimetry ISO 14934-1: Calibration of heat flux meters - part 1: General principles (revision) ISO 14934-2: Calibration of heat flux meters - part 2: Primary calibration 4. Next meetings ISO/TC92/SC1 and its working groups and task group will meet on 2 to 5 May 2006 in ischia, Italy.
