Regaring the question on "MA Approvals" for China: China requires safety approvals for mining, known as MA (Mei Anquan = Coal Safety). Without MA approval, mining equipment is not permitted to go underground. China has developed a specific approval system for equipment manufactured in China and imported equipment. CCRI Coal Safety Division (MA) manages the certification from Beijing and is supported by 15 testing laboratories throughout China.
Think of MA as being a similar organization as MSHA (Mine Safety and Health Administration) is in the US. Product approvals for MA can either be done as an individual piece of equipment (for a particular serial number of a model) or for effective period certification. Effective period certification involves compliance with the GB3836 series of standards, which are similar to the IEC60079 series, except for being based on earlier versions and having several national differences, a quality audit of the manufacturing facility and meeting the intended function. For the majority of the world, product safety certifications are for safety only, and do not reflect any verification of performance claims. For MA certified equipment, the certified equipment must also be suitable for the stated function.
