Tawg Pov thawj theem ntawm Explosion-Proof kiv cua

1. Cov khoom hluav taws xob hluav taws xob yog txwv kom muab zais raws li kev ruaj ntseg theem siv nyob rau hauv cov nkev explosive cua, faib ua aav: tsam 0, tsam 1, tsam thiab Tsam 2.

2. The classification of gas or vapor explosive mixtures falls into three categories: IIA, IIB, thiab IIC. This classification is primarily based on the Maximum Experimental Safe Gap (MESG) or the Minimum Ignition Current Ratio (MICR).

3. Qhov no txias grouping for igniting a specific medium is divided into several ranges. These include T1: below 450°C; T2: 300°C < T ≤ 450°C; T3: 200°C < T ≤ 300°C; T4: 135°C < T ≤ 200°C; T5: 100°C < T ≤ 135°C; T6: 85°C < T ≤ 100°C.
