Annex ZB
(informative)
Information relevant to equipment and protective systems according to
standards harmonized under Directive 2014/34/EU
ZB.1 Introduction
The requirements laid down in the Directive and the standards harmonized under the Directive are the
basis for the quality assurance of the production process and the assessment of the quality system as
well. The quality system must ensure that the products resulting from the regular production process
comply with the types tested in the EU-type examination and with the applicable requirements of the
Directive.
This annex draws attention to a number of standards harmonized under the Directive which can be
used to gain detailed information on specific requirements. These references might be useful for
manufacturers to check whether the safety-relevant aspects are considered in the quality system and
covered by adequate procedures (see 8). They can also be used for internal or external quality audits
(see 9.1 and 9.2).
In quality system assessments according to Annexes IV and VII of Directive 2014/34/EU performed by
a Notified Body the auditing team must have knowledge with regard to the product specific
requirements according to the Directive.
NOTE The following examples do not cover all protection concepts and product specific requirements but
give some advice and will be supplemented to in the next edition.
ZB.2 Non-electrical equipment (EN 13463-1)
Safety aspects are covered by clause A.14 for non-electrical equipment (EN ISO 80079-36).
ZB.3 Protection by flow restricting enclosure "fr" (EN 13463-2)
Safety aspects are covered by the general clause for non-electrical equipment (EN ISO 80079-36).
ZB.4 Protection by flameproof enclosure "d" (EN 13463-3)
The same safety aspects as for electrical equipment apply (see A.3; for aspects of dust ignition
protection, see also A.10).
ZB.5 Protection by constructional safety "c" (EN 13463-5)
Safety aspects are covered by clause A.15 for non-electrical equipment (EN ISO 80079-37).
ZB.6 Protection by control of ignition sources "b" (EN 13463-6)
Safety aspects are covered
