ТР ТС 012/2011 于爆炸环境中使用的设备安全性（防爆产品） 海关联盟成员国在2011年发布了防爆产品安全技术法规：ТР ТС 012/2011 于爆炸环境中使用的设备安全性（防爆产品）对于出口到海关联盟成员国的防爆产品或防爆配件生产商必须要符合该技术法规的要求。The Ex-Proof Equipment Certificate/防爆认证也称之为TR CU-Ex（(Explosibles)）防爆认证或者海关联盟CU-TR 012/2011 技术法规认证，EAC- Ex防爆认证。这是证明并确认产品符合防爆相关标准的证明文件。防爆认证是针对的设备整体，所以对于设备的附件和各组成部件都属于Ex执行范围。
"q" - powder filling;
"s" - special protection;
2) electrical equipment intended for use in explosive dust atmospheres:
"t" ("ta", "tb", "tc") - protection by enclosure;
"i" ("ia", "ib") - intrinsic safety (intrinsically safe electric circuit);
"m" ("ma", "mb", "mc") - encapsulation by compound;
"p" - pressurization;
"s" - special protection;
3) non-electrical equipment intended for use in explosive atmospheres:
"c" - protection by constructional safety;
"b" - protection by control of ignition source;
"k" - protection by liquid immersion;
"d" - protection by flameproof enclosure;
"fr" -protection by flow restricting enclosure;
"p" - pressurization;
4) other recognized types of explosion protection.
Manufacturer (person authorized by the manufacturer), importer submits to the certification (conformity (confirmation) assessment) body a set of the documents for equipment to confirm compliance of equipment with explosion safety requirements of this Technical Regulation of the Customs Union, including:
application for certification;
copies of representative’s constitutive documents (Certificate of registration, extract from the Unified State Register of Legal Persons (ЕГРЮЛ in Russian) and the Main State Registration Number (ОГРН in Russian);
a copy of the agreement on assignation of powers between the manufacturer and manufacturer's authorized representative;
technical specification (if available);
operating documents;
list of standards equipment complies to from the List of standards specified in cl.1 of Article 5 of this Technical Regulation of the Customs Union (if used by the manufacturer);
explanatory note with description of the used engineering solutions and risk assessment, confirming the fulfillment of explosion safety requirements of this Technical Regulation of the Customs Union, if the standards do not exist or do not apply;
certificate of conformity of the manufacturer’s quality management system (if available);
contract (supply agreement) or shipping documentation (for the batch of equipment).
