BS 476-21:1987承重材料耐火性測試
BS 476-21 Fire test on building materials and structures-Part 21: Method for Determination of the fire resistance of load bearing elements of construction.
BS 476-21 建築材料和構件的防火測試-第21部分: 承重材料耐火性測試
This part, together with BS 476: Parts 20, 22, 23 and supersedes BS 476: Part 8:1972, which is withdrawn. However, the latter will still be made available on request, since it is referred to in the building regulations and other legislative documents.
BS 476-21:1987主要用於如下方面
Determination of the fire resistance of beams 橫樑的耐火測試
Determination of the fire resistance of columns 圓柱的耐火測試
Determination of the fire resistance of floors and flat roofs 地面材料及天花板的耐火測試
Determination of the fire resistance of walls 牆體的耐火測試
BS 476-21測試方法，樣品暴露下高溫高壓條件下，測試樣品在規定時間內的承重量，完整性、隔熱性。BS476-21耐火測試標準與BS476-20,BS476-22,BS476-23標準結合使用。睿督公司提供提供Warringtonfire實驗室英國UKAS資質實驗室所簽發BS476-21檢測報告,諮詢電話：+86 25-8658 3475.
