To ensure the explosion-proof performance, after the raw materials are melt with scientific ratio, QC personnel will take sample piece to do drop weight and friction test according to GB/T 10686-2013 standard. The test is conducted under the highest level ExIIC,  hydrogen concentration 21%. Only if the samples are tested qualified can the next step of production be carried out. 

The explosion-proof performance of WEDO non-sparking tools is guaranteed for lifetime.
