In directive 89/391/EWG the European Union has defined
requirements for safety at work, which later
have been detailed for explosive atmospheres in the directive 1999/92/EG.
The requirements to equipment
for operation in explosive atmospheres have been defined in the direc
-
tive 94/9/EG (also known as ATEX 100a or ATEX 95). In 1996 this directive was implemented into Ger-
man law (11. Geräteschutzverordnung).
Concerning technology these directives only state general requirements. Technical details and test pro-
cedures are „recommended“ in European standards (e.g. for equipment with ATEX conformity: EN 1127,
E50014ff, EN 60079, EN 13463ff.).
Since July 1st 2003 equipment intended for use in potentially explosive atmospheres shall only be sold
if the equipment is in accordance with directive 94/9/EG (ATEX). This applies only to new equipment.
The repair of equipment sold prior to July 1st, 2003 is not affected. Pumps of prior design (pumps with
Ex-approved motor only) must not be brought to the market anymore.
Requirements to user and manufacturer of equipment according to ATEX:
The user of a system according to ATEX has to analyse the overall explosion risks according to direc-
tive 1999/92/EC and has to take adequate measures by means of a risk assessment. The evaluation
and validation of measures has to be documented in an explosion protection document, specifying
among other things the areas classified as potentially explosive (see below). The
inner part of the pump
(pumped gases) and the environment of the pump (outer explosion protection) have to be evaluated
separately. Often the requirements will be different.
The responsibility for the classification of areas with potentially explosive atmospheres into
zones and for the specification of requirements to the equipment (category of equipment, class
of ignition, temperature class etc.) is accountable strictly to the operator of the system.
The equipment used has to comply with these requirements. VACUUBRAND does not advise
customers concerning requirements to the equipment under the specific aspects of the cus
-
tomers applications.
Equipment with ATEX-conformity is to be used by appropriately instructed personnel only.
ATEX marking, intended use:
The marking of the equipment corresponding with the standards (see above) gives the areas in which
the equipment may be used according to its intended use.
Technical data, safety notes and intended use:
See instructions for use!
The equipment must only be used if the instructions for use are read, fully understood and
obeyed.
Clean, check and maintain equipment regularly.
Do never operate a defective equipment.
