General requirements for fusible alloy components for fire protection
1 Scope
This standard specifies the requirements, test methods, inspection rules, and instruction manuals and product data sheets for fusible alloy components for fire fighting.
This standard applies to automatic fire extinguishing and fire protection systems used as temperature control of the use of fusible alloy components.
2 terms and definitions
The following terms and definitions apply to this standard.
2.1
Made of alloy material, susceptible to heat melting and produce the release of the components.
2.2
The force required to apply to the fusible alloy element is required to ensure normal operation.
2.3
According to the use of environmental conditions, the provisions of the release alloy can produce the temperature of the release action.
2.4
At a certain rate of temperature, the temperature of the fusible alloy element in the liquid bath is released.
2.5
The temperature at which the fusible alloy element operates at the temperature rise rate controlled air and the time taken to reach the operating temperature, as the fusible alloy element
A measure of sensitivity.
3 request
3.1 appearance and logo
3.1.1 Fusible alloy components should be neat appearance, no cracks, burrs and scratches and other defects.
3.1.2 fusible alloy components should be marked in the obvious parts of the nominal operating temperature value or in line with the provisions of Table 1 color, and the manufacturer logo or
trademark. Marking should be clear and durable.
Table 1 fusible alloy components nominal operating temperature level corresponding to the color of the color
Nominal operating temperature level/℃ 57 ~ 77 79 ~ 107 121 ~ 149 163 ~ 191 204 ~ 246 260 ~ 302
Colorless white, blue, green and orange
3.2 release action
According to the method specified in 4.2 to test, fusible alloy components in the minimum design load (manufacturer's published value), when the fusible alloy by
After the hot melt should be able to complete the release of flexible and reliable action.
3.3 Strength
3.3.1 Tests as specified in 4.3.1, fusible alloy elements for sprinklers shall be capable of withstanding a maximum design load of 15 times
100h; fusible alloy components for other fire-fighting devices should be able to withstand 5 times the maximum design load of 150h.
