This standard is equivalent to the international standard ISO6790-1986 "Graphic symbols for fire protection equipment for fire protection technical documents". 1 Subject content and scope of application
This standard specifies the basic, auxiliary and independent graphic symbols used in technical documents to represent various types of fire protection equipment. This standard applies to the design, construction and review of the following fire protection projects in new construction, reconstruction and expansion projects. a.
Symbol for fire extinguisher,
Symbol for fixed fire extinguishing system:
Symbol for fire water supply line;
Symbol for other fire extinguishing equipment,
Symbol for control and indicating equipment;
Symbol for alarm initiating device,
Symbol for fire alarm device,
Symbol for fire vent;
Symbol for escape route;
Symbol for fire and explosion hazard area.
2 Basic principles
2.1 Graphic symbols for various types of fire-fighting facilities are generally combined into different graphic symbols by basic symbols and auxiliary symbols as needed. 2.2 Symbols used alone are graphic symbols used alone. 2.3 The proportions of all graphic symbols on the same drawing should be the same and should be adapted to the proportions of the drawing. The size of the symbol should be suitable for microcopying. 3 Basic symbols
Symbols of this category indicate the category of fire-fighting equipment. No.
