DIRECTIVE 2014/68/EUScope
The Directive fixes essential safety requirements for making available on themarket of pressure equipment.

This Directive shall apply to the design, manufacture and conformity assessment ofpressure equipment and assemblies (1) with a maximum allowable pressure PS
greater than 0,5 bar.
The essential safety requirements laid down in this Directive arecompulsory:
The manufacturer is under an obligation to analyse the hazards and risks in order to
identify those which apply to his equipment on account of pressure; he shall then design andconstruct it taking account of his analysis.
(1) ( ‘pressure equipment’: vessels, piping, safety accessories and pressure accessories,‘vessel’: a housing designed and built to contain fluids under pressure including its direct attachments
up to the coupling point connecting it to other equipment.
Hermetic compressors are considered vessels.

When placing their pressure equipment or assemblies on the market or using themfor their own purposes, manufacturers shall:•ensure that they have been designed and manufactured in accordance withthe essential safety requirements set out in PED• draw up the technical documentation file• carry out the relevant conformity assessment procedure• draw up an EU declaration of conformity• affix the CE marking• Issue instruction and safety information
Source: PED2

PRESSURE EQUIPMENT SUBJECT TO PED

The following pressure equipment shall satisfy the essential safety requirements set out in PED:
Article 4(1)(a)(i), first indent:
For fluids in Group 1, vessels with a volume greater than 1 L and a product of PS and V
greater than 25 bar·L, or with a pressure PS greater than 200 bar (see PED Annex II, table 1),
Article 4(1)(a)(i), second indent:
For fluids in Group 2, vessels with a volume greater than 1 L and a product of PS and V isgreater than 50 bar·L, or with a pressure PS greater than 1 000 bar, (see PED Annex II, table 2);

Group 1: Flammable gas
Group 2: practically all the other gases‘volume (V)’ means the internal volume of a chamber: the volume of the mechanical parts is tobe excluded from the volume to be taken into account but not the volume of the oil contained.

CLASSIFICATION OF PRESSURE EQUIPMENT
Pressure equipment shall be classified by category.
Category classification is base on:
1. Volume (V) of the vessel
2. Maximum allowed pressure PS of the vessel
3. Gas Group

Group 1 – Flammable gasGroup 2 – Other gas

CONFORMITY ASSESSMENT PROCEDURES

The procedures (*) is determined by the category of the equipment and using
specific “Module” indicated for the various categories.
Embraco Nidec, base the conformity assessment and marking (**) on its Full Quality
System approved by a Notification Body.
This is evidenced by the Module H reported on the declaration of conformity of Cat ll
compressors.

Note: MODULE H: CONFORMITY BASED ON FULL QUALITY ASSURANCE . Module H is a module for Catlll: the manufacturer may also choose to apply one of the procedures which apply to a higher category,
however the marking has to be according to category of the equipment(*) the manufactures may choose the procedure among those laid down in the category of the equipment.
(**) Marking: Cat l: CE; Cat ll: CE followed by Notification Body code, PS (maximum pressure for which theequipment is designed) and PT (test pressure)

PRESUMPTION OF CONFORMITY

Pressure equipment or assemblies which are in conformity with harmonized standards (*)
shall be presumed to be in conformity with the PED
The materials used for the manufacture of pressure equipment which are in conformity with
European approvals for materials, shall be presumed to be in conformity with the PED.
This conformity is requested for equipment Cat ll.

(*) ‘harmonized standard’ means harmonised standard as defined in point (c) of Article 2(1) of Regulation (EU)No 1025/2012;

REQUIREMENTS FOR PED CAT ll
The equipment manufacturer shall take appropriate measures to ensure:• That the material used conforms with the required specification• Keep their traceability
For the main pressure-bearing parts of equipment in categories II, this shall take the form of acertificate of specific product control.
Where a material manufacturer has an appropriate quality-assurance system, certified by a competent bodyestablished within the Union and having undergone a specific assessment for materials, certificates issued by themanufacturer are presumed to certify conformity with the relevant requirements of this point• operating procedures and personnel shall be approved by a competent third party (*) which,at the manufacturer’s discretion, may be:— a notified body,— a third-party organization recognized by a Member State as provided for in Article 20.
(*) In Cat l the personnel shall be suitably qualified according to suitable operating procedures.
Note: Embraco design for use at max 43 °C ambient temperature → NJX is Category II; OEMs may design theirpressure assembly for a lower temperature that may allow to classify the assembly as Category I even using Cat IIcompressors
