the Customs Union "On safety of equipment intended for use in explosive
atmospheres" (TR CU 012/2011)
List
of standards based on which the compliance with the Technical Regulation of the
Customs Union «On safety of equipment intended for use in explosive
atmospheres» (TR CU 012/2011) will be provided
List of standards containing rules and
methods of investigations (tests) and measurements, including the rules of
sampling required to implement and enforce the requirements of the Technical
Regulation of the Customs Union «On safety of equipment intended for use in
explosive atmospheres» (ТР ТС 012/2011) and conformity assessment of products
This Technical
Regulation of the Customs Union sets out the requirements to equipment intended
for use in explosive atmospheres, the compliance with which provides its safe
use in explosive atmospheres.
Depending on the
special measures applied to prevent ignition of the surrounding explosive
atmosphere one type or combination of several types of explosion protection may
be applied to:
1) electrical
equipment intended for use in explosive gas atmospheres:
"d" -
flameproof enclosure;
"e" -
increased safety;
"i"
("ia" , "ib", "ic") - intrinsic safety
(intrinsically safe electric circuit);
"m"
("ma", "mb", "mc") - encapsulation by compound;
"nA" -
нnon-sparking equipment;
"nC"-
enclosed-break devices, hermetically-sealed device or non-incendive components
producing arcs, sparks or hot surfaces;
"nR"-
restricted-breathing enclosure;
"nL"-
energy-limited apparatus;
"nZ"-
pressurized enclosure;
"o" -
oil immersion;
"p"
("px", "py", "pz") - pressurization;
"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);
