| Title | Automatic electrostatic spraying equipment for flammable coating powder |
| Project Number | 16945 |
| Abstract/Scope | 1.1 This European Standard specifies requirements for automatic electrostatic spraying equipment which are used for spraying flammable powders which create explosive atmospheres in the spraying area. In this connection distinction is made between spraying devices which due to their type of construction comply with requirements as laid down in EN 50050:2006 as applicable, and those for which other discharge energies and/or current limits are stipulated. It also gives information on the safe operational conditions of the electrical equipment including ventilation requirements. Additional requirements as to the construction of the spraying areas such as cabins, booths, etc. are dealt with in EN 12981. 1.2 This European Standard considers the following three types of electrostatic spraying systems. Type A Systems complying with EN 50050:2006 with a discharge energy limit of 2 mJ (see 5.1.1) In these systems there is no danger of either electric shock or discharges of incendive energy. Type B Systems with a discharge energy in excess of 2 mJ but less than 350 mJ and a current limit of less than 0,7 mA (see 5.1.2) In these systems there is no danger of electric shock but there are dangers from discharges of incendive energy. Type C Systems with a discharge energy in excess of 350 mJ and/or a current in excess of 0,7 mA (see 5.1.3) In these systems there are dangers of electric shock and from discharges of incendive energy. 1.3 This European Standard considers the hazards specific to explosive atmospheres created by the electrostatic spraying process. 1.4 The automatic electrostatic spraying equipment for flammable coating powders shall be constructed suitable for group II category 3 as defined in EN 60079-0. 1.5 This European Standard does not deal with matters of noise created by the equipment. For this item, the requirements are laid down in EN ISO 11688-1. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
