GB/T 33486-2017Ships and marine technology -- Large yachts -- Structural fire protection for FRP yachts (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the translation method equivalent to the international standard ISO 14886..2014 "ship and maritime technology large yacht FRP boat structure

Fire ".

This standard has made the following editorial changes.

--- Chapter 4 Tibmw to tibmw.

This standard is proposed by China Shipbuilding Industry Corporation.

This standard is nationalized by the National Marine Vessel Standardization Technical Committee Large-scale Yacht Subcommittee (SAC/TC12/SC9).

The drafting unit of this standard. China Shipbuilding Industry Comprehensive Technology and Economic Research Institute, Tian Guang Fire Co., Ltd., Guangzhou Yong Cheong fire equipment

Co., Ltd., Zhoushan City Quality and Technical Supervision and Testing Institute.

1 Scope

This standard applies to the ship is not less than 24m, carrying the number of not more than 12 large FRP yacht structure fire. This standard is not suitable

Manufactured in accordance with the SOLAS Convention.

This standard uses the Fourier heat transfer coefficient according to the IMOFTP rule to determine the equivalent resistance of all FRP laminates

Fire model.

This method takes into account the mechanical, thermal, physical and thermal insulation properties of insulating FRP laminates.

The thermal insulation and FRP materials specified in this standard heat, smoke, fire and other technologies and equivalent insulation performance as a fire

FRP laminate with material.

Due to the opening, doors, windows, hatchways, etc. of the laminate, it is possible to reduce the heat, smoke and fire resistance of the separation. This standard does not apply to this

Heat-resistant, smoke-proof and fire-resistant requirements for open accessories.
