SS 489:2015+C1:2017 Specification for Fire ShutterSSS 489:2015+C1:2017 Specification for Fire Shutters Nanjing Ruidu Fire Retardant Testing Fire Resistance Testing of Components.
The fire resistance of fireproof shutters should be judged from one or more of the following aspects.
Loss of stability: The component loses its support ability or anti-deformation ability during the test, and the parameters to determine the loss of stability of the specimen are the deformation amount and deformation rate.
Loss of integrity: The specimen is considered to have lost its integrity if any of the following limitations occur in the component.
The cotton pad was set on fire.
A 6mm diameter crevice probe can glide through a crack and glide up to 150mm, or a 25mm diameter crevice probe can penetrate completely.
Flames appear on the backfire side and last for more than 10s.
Loss of thermal insulation: If the temperature rise of the backfire surface of the specimen exceeds any of the following limits, the specimen is considered to have lost thermal insulation.
The average temperature rise exceeds the initial average temperature by 140 °C.
The temperature rise at any point exceeds the initial temperature (including moving thermocouples)180 (initial temperature refers to the initial average temperature of the backfire surface at the beginning of the test).
The Singapore Civil Defence Force (SCDF) attaches great importance to the selection of building products in terms of fire safety in buildings. These products may be in discrete form, such as fire doors and fire extinguishers, or they may be non-discrete in nature, such as fire-resistant partitions and glass blocks.
The correct selection and installation of these products ensures that the intent of the approved fire safety plan is achieved, i.e., in the event of a fire, occupants are able to evacuate quickly to a safe area, the spread of smoke and fire is controlled, the fire protection system is able to function properly, and the SCDF is able to carry out rescue and firefighting operations.
As a result, SCDF has invested a great deal of time and effort to ensure an adequate level of control over the products entering the building. SCDF has partnered with TÜV SÜD to use PLS as a tool for the approval of building products from a fire safety perspective. The SCDF's new role in this approval process will be to develop requirements and enforcement. TÜV SÜD will carry out product controls such as type testing, batch testing, factory audits, market and factory surveillance, labelling, listing and listing catalogue publication in accordance with the PSB product launch plan.
With the implementation of PLS, qualified personnel should choose the fire safety products listed under PLS to meet the requirements of the fire code. The product should be constructed according to the test sample. The material used should be the same as the test structure. The use of the listed products is required to comply with the SCDF's Code for Fire Protection in Buildings.
No modifications may be made to the prototype design. If modifications cannot be avoided due to on-site construction constraints or other reasons, a satisfactory test evaluation report should be submitted to TÜV SÜD for further consideration, verification and approval of modifications. The list of fire safety products and their requirements is shown in the table below.
