This paper is intended to verify in advance the intended use of the
ETH electro cylinder in explosive atmospheres and to define the ATEX
application data required for the temperature measurement in the
ATEX certification procedure.
The operating / mounting instructions must be taken into account and
applied when mounting, setting up and maintaining the device.

ATEX = “ATmosphère EXplosible”
Introduction to the European ATEX directive
1.3.1. Explosive atmospheres
Directive 94/9/EC defines an explosive atmosphere as a mixture of:
a) flammable substances - gases, vapors, mists or dusts
b) and air
c) under defined atmospheric conditions
d) in which, after ignition has occurred, combustion spreads to the entire unburned
mixture
(NOTE: dust may not burn entirely after ignition).
A “potentially explosive atmosphere” is an atmosphere which could become
explosive due to local and operational conditions. Devices concerned by directive
94/9/EC are defined as designed for the use in potentially explosive atmospheres.
1.3.2. Harmonized European ATEX Standard
The EU accepted two harmonized directives for health and safety.
Requirements for machinery and equipment
Directive 94/9/EC (ATEX 95a) defines the minimum safety requirements in EU
member states for products used in potentially explosive atmospheres.
Requirements for OEM / user
ATEX directive 99/92/EC (ATEX 137) sets out the minimum requirements for
improving the health and safety protection of workers potentially at risk from
explosive atmospheres with regard to workplace, working conditions and the
handling of products and materials. This directive classifies the workplace into
zones and defines criteria for categorizing the products within the zones.

1.3.3. Zone classification / device categories
The table below describes the zones of an installation, where potentially explosive
atmospheres may occur. The proprietor must analyze and assess the area, where
explosive gas/dust mixes may occur and, if necessary, subdivide them into
individual zones. This zone classification permits to select suitable machinery and
equipment which can be used in this area.

1.3.4. Type of explosion protection
In addition to category and device class, which are the minimum required
information, the device or component designation gives additional information with
reference to the type of protection and explosion group for gases and mists.
The type of explosion protection defines which method or measures is/are used for
explosion protection in given equipment or individual components.
For non electric equipment, the following types of explosion protection are possible:
Type of explosion protection
Designation
Applied standard
Flameproof enclosure
d
EN 13463-3
Pressurized apparatus
p
EN 13463-7
Intrinsic safety
g
EN 13463-4
Restricted breathing
h
EN 13463-2
(except category 1)
Constructional safety
c
EN 13463-5
Ignition source monitoring
b
EN 13463-6
Liquid immersion
k
EN 13463-8
For Parker’s ETH electro cylinders, the constructional safety "c" method is applied.
1.3.5. Explosion subgroup
The explosion group is an indicator for the inflammability (explosive potential) of
gases (explosive atmospheres). The requirements for the equipment increase from
IIA to IIC.
Explosion subgroup
Examples for gases
IIA
Propane, acetone, ammonia, gasoline, benzene,
diesel fuel, heavy fuel, methane, methanol, propane
IIB
Ethylene, ethyl alcohol, hydrogen sulphide
IIC
Hydrogen, carbon disulphide, acetylene
Gas explosion subgroups of the Parker ETH electro cylinder (see on page 10).
1.3.6. Temperature classes
Classification of flammable gases and vapors depending on their ignition
temperature:
Class
Maximum permitted material surface temperature [°C]
T1
450
T2
300
T3
200
T4
135
T5
100
T6
85
For flammable substances, the temperature class and the maximum permitted
surface temperature of the equipment are of essential importance.
1.3.7. ATEX and machinery directive
The ATEX directive is in effect since July 1st. 2003 and replaces the individual laws
of the respective countries with reference to explosive atmospheres. While
previously only referring to electrical devices, the directive now does also comprise
mechanical, hydraulic and pneumatic devices.
With reference to the machinery directive 2006/42/EC it must be taken into
consideration, that a number of external requirements stated in the ATEX directive
94/9/EC refer to dangers occurring in explosive atmospheres, whereas the
machinery directive does only list requirements for explosion protection.
Hence, the ATEX directive 94/9/EC is superior to the machinery directive with
reference to explosion protection in potentially explosive atmospheres. The
requirements of the machinery directive are however valid for all other dangers
when operating machines.
