BT4 लाई कक्षा बी तापमान समूहको रूपमा वर्गीकृत गरिएको छ, जहाँ T4-मूल्याङ्कन गरिएका उपकरणहरूको सतहको अधिकतम तापक्रम १३५ डिग्री सेल्सियसभन्दा बढी हुँदैन. CT4 ले क्लास C विस्फोट-प्रूफ रेटिङ राख्छ, BT4 सँग तुलनात्मक, and is suitable for environments with hazardous gases such as hydrogen and acetylene, maintaining a maximum surface temperature of 135°C.
Scope of Use
BT4 is suitable for common gases including methane, ethane, पेट्रोलियम, र हाइड्रोजन sulfide.
CT4 encompasses a broader range of less common विस्फोटक ग्यासहरू, such as hydrogen and water gas at the CT1 level, acetylene at the CT2 level, and carbon disulfide at the CT4 level.
