UNECE WP.6 SIEEEA global regulation approach

WP.6 SIEEE

Frank LieneschPhysikalisch-Technische Bundesanstalt

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.

CRO Part 1: Requirement for the equipmentPlacing on the market

» Elimination of possible ignition sources in accordance to intended use of the equipment, typical ignition sources are:

» Hot surfaces» Electrical sparks» Mechanical sparks» Electrostatic

» Validated protection concepts (“Types of Protection”) have to be applied

» 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)

EN 1127-113 Ignition sources

IEC/ISO 60079-”X” / 80079-”X”

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)

» IEC-Zone Classification Concept (Zones for Gas and Dust) with the applicable Equipment Protection Levels

» The equipment and its installation need to be inspected and maintained

» 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 1 and 2:

2. UNECE WP.6 SIEEE

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 Laboratorieshas 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 » IECExare 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 conceptof 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 StandardsIECEx 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”
