General Information

ATEX Introduction

The ATEX Directive 2014/34/EU specifies the minimum safety requirements for equipment intended for use in potentially explosive atmospheres in European Union member states. ATEX is derived from the French term ATmosphères EXplosives.
Hydraulic motors are designed for mobile and stationary applications. Some motors are used in related applications, where locations are classified as hazardous areas.
The equipment intended for use in hazardous areas are divided into two groups:
Group I: Equipment intended for use in underground parts of mines (mining equipment).
Group II: Equipment intended for use in other places than mines (non-mining equipment).
The Danfoss hydraulic motors, type H1B are intended for use in Group II applications.

Explosive atmosphere

Explosion triangle

A “hazardous area” is defined as an area in which the atmosphere contains, or may contain in sufficient quantities, flammable or explosive gases, dusts or vapours. In such an atmosphere a fire or explosion is possible when three basic conditions are met. This is often referred to as the “hazardous area” or “explosion” triangle.
An atmosphere with the potential to become an explosive atmosphere during operating conditions and/or under the influence of the surroundings is defined as a potentially explosive atmosphere. Products covered by directive 2014/34/EU are defined as intended for use in potentially explosive atmospheres. Removing one of the elements eliminates all risk of explosion.

General zone classification

Directive 99/92/EC divides the Hazardous areas into zones and defines criteria by which products are categorized within these zones; Zone 0 / 20 is the most restrictive and Zones 1 / 21 and 2 / 22 are less restrictive. The following table describes the zones in an installation where there is a potential for explosive atmospheres. The owner of the installation must analyze and assess the area in which the explosive gas/dust mixture may occur, and if necessary must divide it into zones. This process of zoning then allows the correct plant and equipment to be selected for use in the area.

Equipment category and zones

Mechanical components with potential ignition sources e.g. components containing non-conductive materials or layers or components with hot surface are covered by the ATEX-directive.
Non-mining equipment for potentially explosive atmosphere is classified as: Equipment Group II – this group comprises three categories according to the level of safety provided:
•
Category 1
•
Category 2
•
Category 3
Category 1 equipment has the highest degree of protection – see the following below.
These products have to fulfil all requirements in the ATEX directive, and have to be marked with the required “Ex” marking.
Equipment located in zone specified areas must fulfil the following requirements (see also the following figure):
Category 3 – approved equipment can be installed in hazardous areas zone 2 / 22 and outside zone
•
categorized areas. Category 2 – approved equipment can be installed in hazardous areas zone 1 / 21, zone 2 / 22 and
•
outside zone categorized areas.

General Information

Contents of marking

The rules for the marking of systems, equipment and components are uniformly defined in the standards relating to the general technical requirements – EN 13463-1 for mechanical equipment.
A priority for all Ex equipment and protective systems is that the marking should show the areas of their designated use. Components covered within the scope of the ATEX directive have to be CE-marked, and marked with the specific “Ex”-sign.
Principle
The marking must indicate the following:
•
The manufacturer who has put the item of equipment on the market
•
Manufacturer’s type identification
•
Year in which the equipment was manufactured
•
A serial number
And further the ignition protection marking
•
Symbol of the equipment group and category (M1 or M2 for group I mining equipment, or 1 or 2 or 3 for Group II non-mining equipment).
Additionally for Group II equipment only:
1. The letter “G” where explosive atmospheres caused by gases, vapours or mists are concerned;
and/or
2. The letter “D” where explosive atmospheres caused by dusts are concerned.
•
Type of ignition protection system.
•
Where appropriate, symbol of explosion group of the equipment.
•
For Group II equipment, the symbol indicating the temperature class or the maximum surface temperature in °C, or both.
