1. Introduction
Interest of the Industry using Ex-Products
Users in the chemical and petroleum industry act more and more
globally with a single engineering approach for their plants
 to earn savings of engineering, installation and
maintenance costs
 to buy the equipment in a larger number and to get a better
price per piece
 to have benefit from the global competition under manufacturers
Barriers against this tendency are domestic rules and regulations
which require special engineering for the plants from country to
country.
1. Introduction
Interest of the Industry manufacturing Ex-Products
Manufacturers want to sell and manufacture their products
 without additional national differences for the product and
delays to the market
 in accordance to one global standard (IEC / ISO)
 without double-testing of their product
 without formal restrictions to place it on the market
Barriers against this tendency are domestic rules and
regulations which require special differences for the
product from country to country.

Intention of the Common Regulatory Objectives (CRO)
 to cover comprehensively all relevant issues
in order to achieve an globally accepted safety level
 to provide a global „Best Practice“ model as a template
for national regulation
 Focus to the main objectives
 Easy to understand
 Open for national modifications
 Specify the distributed roles and related responsibilities of
the involved parties:
 Regulator
 Market Surveillance
 Certification Body
 Manufacturer
 End user
 Open for ongoing maintenance and modification

2. UNECE WP.6 SIEEE
CRO Part 1: Requirement for the equipment
Placing on the market
» Elimination of possible ignition sources in accordance to intended use of
the equipment, typical ignition sources are:
» Hot surfaces
EN 1127-1
» Electrical sparks
13 Ignition sources
» Mechanical sparks
» Electrostatic
» Validated protection concepts (“Types of Protection”) have to be applied
IEC/ISO 60079-”X” / 80079-”X”
» Instructions (manual) about the intended use, installation and repair
» Conformity assessment procedure in accordance to an international
certification scheme such as IECEx (IECEx procedure can be seen
as a reference)
2. UNECE WP.6 SIEEE
CRO Part 2: Safe use of the equipment
» Classification of the substances in accordance to:
» Ignition Temperature
» Explosions Groups (Ignition Energy)
Ex d e IIC T3 Gb
» IEC-Zone Classification Concept (Zones for Gas and Dust) with the
applicable Equipment Protection Levels
IEC 60079 -10
» The equipment and its installation need to be inspected and maintained
IEC 60079 -14, -17,-19
» Requirements for the competency of persons (selection, installation, use of
the equipment)
» Requirements for service facilities (e.g. repair workshops)
» The Explosion risk assessment of an individual plant needs to be documented
in the “Explosion Protection Document”

CRO Part 3: Standards reference list
» Accepted Standards (ISO/IEC) are listed in an annex to the regulation
» The standards has to be accepted by a Standard Acceptance Group
» After the acceptance the Standards can be applied by manufacturers and
end users to show compliance with the regulation
» All countries which have implemented the Regulation enjoy the advantages
like barrier free trade of explosion protected equipment and equal conditions
for operating a plant bearing explosion risks
2. UNECE WP.6 SIEEE
CRO Part 4: Conformity assessment bodies
» The accreditation body has to be a member of ILAC/IAF
» The accreditation of
» Conformity Assessment Bodies
» Test Laboratories
has to follow the applicable ISO/IEC-Standards
» One member of the assessor team needs competence in the field of
explosion protection (see e.g. the list of approved IECEx assessors).
» Procedures and Rules of the IEC Conformity Assessment System IECEx
is to take as a reference for conformity assessment
2. UNECE WP.6 SIEEE
CRO Part 5: Steering Committee
» An Explosion Protection Steering Committee is to formed and operated
under the umbrella of UNECE WP.6 (ExSC) to monitor the application
experiences
» All member having implemented the CROs can participate in the
Explosion Steering Committee (ExSC)
» ExSC notifies the members of the Standard Acceptance Group
» Observers like
» Standardization Organization (IEC/ISO)
» Market Surveillance
» IECEx
are also invited to attend the meetings
2. UNECE WP.6 SIEEE
CRO Part 6: Market surveillance
» A Market Surveillance network specialized in Ex-Equipment is to be
formed and operated (UNECE-ExMars)
» For critical non-conformance of Ex-Equipment an
Alert-System is necessary
Ex - Market Surveillance Concept based on the general concept
of the „MARS“ Group
Strategy:
• Developing a general procedure for market surveillance (GMSP)
• Increasing cooperation with stakeholders and sharing the work
of Market Surveillance internationally
• Increasing the visibility of Market Surveillance to the outside
world

What is IECEx?
The single International IEC System with Schemes
covering Certification to Standards that relate to
Equipment and Services in areas relating to Explosive
Atmospheres, to provide an Internationally accepted
means of demonstrating claimed compliance with
International Standards
IECEx is a “Conformity Assessment Tool” providing
confidence that Products, Services and Personnel covered
by an IECEx Certificate meet specified requirements,
(International Standards)
“IECEx is the International Standard way of doing Ex Certification”
