Shenhai Explosion-Proof
Iki nggambarake konsep sing beda banget.
| Kategori Kondisi | Klasifikasi Gas | Gas perwakilan | Energi Spark Ignition Minimal |
|---|---|---|---|
| Ing Tambang | aku | Metana | 0.280mJ |
| Pabrik ing njaba Tambang | IIA | propana | 0.180mJ |
| IIB | Etilena | 0.060mJ | |
| IIC | hidrogen | 0.019mJ |
IIC biasane digandhengake karo lingkungan sing tahan bledosan, ditondoi dening zat kayata hidrogen lan etil nitrat. Kosok baline, IIIC, minangka ditetepake dening standar nasional, gegayutan karo bledug bledug konduktif, ditetepake minangka DIP A21. IIIA covers gampang kobong fibers, lan IIIB kalebu bledug non-konduktif.
IIC is not interchangeable with IIIC; mulane, products with dust explosion-proof ratings such as DIP A20/A21 should be chosen.
