尋求UL94防火規格的資料

    UL94防火規格﹐什么樣的材料用什么樣的防火規格(94HB,94v-0,94v-1,94v-2)。ABS,PC,PP,POM,PCB板等它們是要用哪一種?

即便是同一种材料，它的防火等级也可以是不一样的。

      是不是要看產品的使用環境來定﹐比如說家用電器﹐炸驢﹐吸塵器﹐消費性電子產品﹐他們用的環境不同﹐定的防火等級就不一樣。

相应的产品会有相应的安规，安规上有规定。

UL 94 V-0, V-1, V-2 flammability standard(UL94 V-0, V-1, V-2可燃性標準)
Specimen 試片
  
Length 125 mm (5 in) x Width 13 mm (0.5 in) x Thickness [typically 0.7 mm (1/32 in) or 1.5 mm (1/16 in) or 3.0 mm (1/8 in)].  
  
長125mm(5")X寬13mm(1/2")X厚度[一般為0.7mm(1/32")、1.5mm(1/16")、3mm(1/8")厚]
  
Procedure 程序  
  
A total of 10 specimens (2 sets) are tested per thickness.  
每一厚度總共10個試片(分為兩組)被測試。
  
Five specimens of each thickness are tested after conditioning for 48 hours at 23 degrees C and 50% RH.  
每一厚度取5個試片為一組在23℃和50%下放置48小時後再測試。
  
Five specimens of each thickness are tested after conditioning for 7 days at 70 degrees C.  
同一厚度另取5個試片為一組在70℃下放置7天後再測試。
  
Each specimen is mounted with long axis vertical  
每一試片以長軸垂直地面方式固定。  
Each specimen is supported such that its lower end is 10 mm above Bunsen burner tube.  
試片上端被支撐以致下端高於本生燈10mm。
  
A blue 20 mm high flame is applied to the center of the lower edge of the specimen for 10 seconds and removed. If burning ceases within 30 seconds, the flame is reapplied for an additional 10 seconds. If the specimen drips, particles are allowed to fall onto a layer of dry absorbent surgical cotton placed 300 mm below the specimen.  
藍色20mm高火焰燃燒試片下端邊緣中心10秒鐘，然後移開。 假如試片在30秒之內停止燃燒，則本生燈火焰再次燃燒試片下端邊緣中心10秒鐘。假如試片熔化，則滴下來的火焰分子會掉落在距試片下端300mm處之棉花層。

兄弟們,頂頂啦再上傳!!!

thank you very much !

Requirements for V-0 (V-0的要求條件)
