Introduction
This document is a type C standard as stated in EN ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document. The machinery concerned and the extent to which hazards, hazardous
situations and events are covered are indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
standards, for machines that have been designed and built according to the provisions of the type C
standard.
It has been assumed that the use of the equipment for dispensing of fuels will be by untrained persons
(user/dispenser), while other aspects of the operation, maintenance, etc., will be by designated and
trained personnel (station personnel or operator).
Measures in addition to those required by this document are expected to be assessed if the metering
pump or dispenser is intended for use and storage at temperature outside of the range stated in the Scope.
The manufacturer should demonstrate the suitability of the metering pump or dispenser design over the
full temperature range, and the temperature range should be marked in accordance with 7.4.1. The need
for and nature of additional requirements should be determined by the manufacturer, if necessary, after
consulting the installer and user.

5 Safety requirements and/or protective measures
5.1 Explosion protection measures
5.1.1 Explosion protection measures should be taken in accordance with Annex B.
5.1.2 Equipment, components and protective systems used within hazardous areas, shall be suitable as
a minimum requirement for Explosion Group IIA with temperature class T3 as defined in
EN IEC 60079-0:2018 and EN ISO 80079-36:2016.
5.2 Selection of equipment
5.2.1 General
5.2.1.1 Hazardous areas considered in this document are only those created by an individual
metering pump/dispenser in open air.
NOTE 1 The following requirements for classification of zones are not intended to release the user of the
equipment from their obligation to verify the correct classification as far as workplaces are concerned, and to
implement additional health and safety arrangements if necessary. Required documents are identified in 7.3.
NOTE 2 Further information relating to equipment for use in hazardous areas and zones is given in Annex B.
NOTE 3 Information on additional hazardous areas associated with vehicle refuelling is given in Annex D.
5.2.1.2 The use of the expression ‘hazardous areas’ and ‘zones’ within this document is restricted to
the selection of equipment, protective systems and protective measures.
5.2.1.3 All references to the degree of protection IP54 shall be taken as IP54 category 2 according to
EN 60529:1991 . All external surfaces with an IP rating requirement of IP54 or greater shall be subjected
to an impact test according to EN IEC 60079-0:2018 Group II equipment, high risk of mechanical danger.
After impact, the surface shall meet its required IP degree of protection.
5.2.1.4 Hazardous areas are created in and around metering pumps/dispensers. The extent of
hazardous areas can be limited by the use of Type 1 or Type 2 vapour barriers.
5.2.1.5 Enclosures for use in zone 2 areas shall either:
a) use equipment suitable for the zone of hazard selected from EN IEC 60079-0:2018 where totally
immersed in a zone 2 or
b) have a minimum level of ventilation such that the breathing area of the enclosure shall have at least
80 % of its surface in a non-hazardous area and shall meet the breathing requirements of 5.3.7.4 from
inside the enclosure to a non-hazardous area.
5.2.1.6 The inside of the hydraulic housing of the metering pump/dispenser shall be considered to
be zone 1, where Category 2G, EPL Gb equipment shall be used, unless potential sources of release are
reduced in accordance with EN 60079-10-1:2015. The housing shall be at least IP23.
5.2.1.7 The extent of the hazardous areas external to the metering pump/dispenser are determined
by the following:
a) on the external side of a housing constructed to not less than IP23 and used to constrain a zone 1
area, a zone 2 area exists where Category 3G, EPL Gc equipment shall be used. The zone 2 area is
defined as below (see Figure A.6):
1) limited upwards to 50 mm; and
2) 200 mm horizontally in all directions and downwards to ground projection;
b) on the external side of a housing constructed to not less than IP54 and used to constrain a zone 1
area, a zone 2 area exists where Category 3G, EPL Gc equipment shall be used. The zone 2 area is
defined as below (see Figure A.5):
1) 50 mm in all directions;
2) and downwards to ground projection;
c) on the external side of a housing constructed to not less than IP67 and used to constrain a zone 1
area, no hazardous area exists (see Figure A.1 and Figure A.2);
d) on the external side of a housing constructed to not less than IP23 and used to constrain a zone 2
area, an external zone 2 area exists where Category 3G, EPL Gc equipment shall be used. The external
zone 2 area is defined below:
1) limited upwards to 50 mm; and
2) 200 mm horizontally in all directions and downwards to ground projection.
e) on the external side of a housing constructed to not less than IP54 and used to constrain a zone 2
area, no hazardous area exists if the external side is in open air.
5.2.1.8 The interior of the vapour containing parts of the vapour recovery system is zone 0, where
Category 1G, EPL Ga equipment shall be used.
5.2.1.9 A continuous non-permeable pipe (non-permeable is less than 0,1 g/m /day) provides
separation of hazardous areas (inside) from non-hazardous areas (outside) with the exceptions of 5.2.2.
5.2.1.10 If a pipe containing zone 0 vapour or fuel has a de-mountable joint then there exists a zone 2
area, where Category 3G, EPL Gc equipment shall be used, [as in 5.2.1.7 a)] where the joint is in open air.
5.2.2 Pipe and hose permeability
All fuel or vapour recovery containment in ventilated housings shall have the following limitations to
permeation to allow a zone 1 classification, where Category 2G, EPL Gb equipment shall be used, in the
housing:
a) pipes: less than or equal to 0,2 g/m /day — tested according to EN 14125:2013;
b) hoses: less than or equal to 12 ml/m/day — tested according to EN 13483:2013.
For ventilation requirements refer to 5.3.7.
Conformity shall be demonstrated by pipe or hose supplier’s declarations.
5.2.3 Nozzle area — vapour releases only
5.2.3.1 Around the nozzle in rest position there is an area of 200 mm horizontally and 50 mm
upwards and downwards to ground level as zone 2, where Category 3G, EPL Gc equipment shall be used.
5.2.3.2 Nozzle outside the housing and positioned > 50 mm from the dispenser wall. If the wall is
IP54 within 200 mm horizontally, 50 mm vertically upwards and downwards to ground level from the
nozzle spout then on the other side of the IP54 wall there is no hazardous area due to the nozzle, see
Figure 1 and Figure 2.

5.2.4.1 The inside of the nozzle boot is zone 1, where Category 2G, EPL Gb equipment shall be used.
5.2.4.2 The nozzle boot shall prevent retaining of liquid and be drained to the outside. Drained liquid
shall not create an additional hazard, see Figure 5.
5.2.4.3 When the nozzle boot consists of a pocket and the wall inside the pocket is continuous and
— the wall below the nozzle boot is not less than IP67 downwards to the lower extremity of the wall
containing the nozzle boot and
