San: Mining battery ni a matu ATEX hte IECEx masat masa galaw ai lam gaw hpa shai ai kun?
A: ATEX gaw EU a gat lawk a matu 2014/34/EU a matsun hte maren galaw ra ai rai nna, Notified Body kaw nna jep joi ai lam galaw ra ai. IECEx gaw 30+ hpung shang mungdan ni hta grau dam lada ai mungkan ting masat masa galaw ya ai raitim, Amerikan (MSHA ra ai) shing nrai Miwa (MA ra ai) mungdan ni hta n hkap la ai. Lahkawng yan gaw IEC 60079 hpaji masa langai sha hpe madung tawn ai majaw, chyam dinglik ai jahpan ni hpe lam lapran hta law malawng htawt sit mai ai.
San: Mining battery ntsa kaw Ex masat da ai gaw hpa lachyum rai kun?
A: Ex masat kumla gaw makawp maga ai amyu, gas hpung, nbung katsi ai class, hte jak rung makawp maga ai madang ni hpe encode galaw da ai. Group I lung seng htu sha ai lam a matu, masat masa galaw ai ladat gaw Group II hpaga lam arung arai ni hte shai ai, methane hte nhprang wan n-ga hpe hkan sa ai lam hpe madi madun ai hta grau nna, hpaga lam hta lang ai gas ratings ni hpe n-gun jaw ai.
San: Hpa majaw lamu ga kata na lung seng htu ai shara ni hta standard bawm kapaw ai -n-hkap la lu ai battery ni hpe n mai lang ai kun?
A: Ga npu na lungseng htu ai shara ni hpe Group I ngu masat da ai rai nna, methane gas hte nhprang wan n-ga hpe kalang ta makawp maga ra ai. Group II a matu masat da ai madang dep ai hpaga lam hta bawm kapaw ai lam hpe n-gun jaw ai battery ni gaw, gas langai sha nga ai grup yin ni hpe sha tsun shaga lu nna, lung seng htu sha ai shimlam tara ni hta tsun da ai dual-hkrit tsang hpa makawp maga lam n nga ai.
San: Lungseng htu ai battery ni a matu, bawm kapaw ai lam-sakse hkam ai lam hpe kade daram manu jahpu jaw ra ai kun?
A: Manu jahpu gaw, langai hkrai a gat lawk ATEX masat masa a matu $30,000–$100,000 kaw nna, law law a gat lawk hte bung ai lamang ni a matu $150,000–$500,000 du hkra rai nga ai.
