ISO 834-1 is a standard developed by the International Organization for Standardization (ISO) that provides guidelines for determining the fire resistance of various building elements, including walls, floors, and ceilings. The standard specifies a fire test method that evaluates the ability of these elements to withstand the effects of fire.
ISO 834-1 is part of a series of standards, collectively known as ISO 834, which outlines fire resistance testing procedures. ISO 834-1 specifically de

Building materials play an important role in the fire prevention measures of buildings, so each country has strict corresponding requirements for the flame retardancy of building materials. Among them, the building material fire test standard BS 476 is also one of the important test standards, so what are its requirements for building material fire resistance? BS 476-7 Fire test on building materials and structures－standard name: BS 476-7: Part 7: Method of test to determine the classifica

The reliability test is to expose the product under the environment of natural or artificial environmental conditions, to evaluate the performance of the product under the environmental conditions of actual use, transportation, and storage, and analyze the impact and mechanism of environmental factors and its mechanisms of environmental factors. Construction material reliability test items include:1. Climate and environmental test1) Temperature aging test (high temperature aging,

Fire extinguishers are the most common fire-fighting equipment, so we need to be familiar with what items and standards need to be checked for fire extinguishers to ensure that the fire extinguishers can be used normally. What items should be checked for fire extinguishers? Fire extinguishers should comply with market access regulations, and should have factory certificates and related certificates. The nameplate, production date and maintenance date of the fire extinguisher should be compl

Building exterior wall insulation materials have brought a series of problems while reducing building energy consumption. Among them, the most important fire hazard is building exterior wall insulation materials, and organic insulation materials are easy to burn. The building exterior wall insulation system using organic thermal insulation materials can easily cause the fire to spread rapidly to the entire building in case of fire. That needs to detect the burning behaviour of building

The burning chamber of the building material single burning item test equipment is designed according to the standard requirements of GB/T 20284-2006 "Single burning item test for building materials and products". It is a test device used to determine the fire reactivity of building materials or products (excluding floor coverings and products specified in EC Decision 2000/147/EC) in the single combustion test (SBI).The indoor height of the building material single burning item test co
