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 or hazardous events
are covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or
type-B standards, the requirements of this type-C standard take precedence over the requirements of
the other standards for machines that have been designed and built according to the requirements of
this type-C standard.
1 Scope
This document describes all significant hazards, hazardous situations and events relating to plating and
anodizing lines, when used as intended and in compliance with the foreseeable conditions of the
manufacturer. In addition, procedures for testing and measuring safety requirements, marking of
equipment and minimum operation requirements are specified.
For reference to plating lines and anodizing lines, the term plating line is used in this document.
This document applies to the design and construction of plating lines and anodizing lines, including its
transporter systems, for surface treatment of industrial products by means of inorganic or organic
electrolytes or by means of other process chemistries.
Plating lines and anodizing lines in terms of this document are arrangements of process tanks for:
— electrolytic treatment of workpieces (e.g. electrocleaning, passivation, electroetching, burnishing,
electrolytic polishing and brightening);
— wet chemical treatment of workpieces (e.g. degreasing, passivation, chemical polishing, etching,
pickling, blackening);
— electrolytic and electro-less metal deposition, even on non-metallic workpieces made electrically
conductive by corresponding treatment;
— changing of substance composition on the surface of metallic workpieces, e.g. burnishing,
blackening, phosphating, chromating; and
— anodizing (anodic oxidation);
including rinsing tanks, the corresponding transporter equipment (e.g. transporter systems, handling
gantry, bean, etc.), where the products are lifted in and out of tanks, and drying equipment.
This document distinguishes between the following types of plating lines:
— Type 1: manual lines;
— Type 2: semi-automatic lines;
— Type 3: fully automatic lines.
Furthermore, it specifies equipment marking and requirements on user information.
This document does not deal with hazards resulting from plating lines parts above category 1 of PED
(Pressure Equipment Directive).
This document is not applicable to:
— transporter systems of carrousel lines (see EN 618:2002+A1:2010 and EN 15095:2007+A1:2008);
— equipment for the preparation and treatment of water and wastewater;
— machinery for dip coating and electro-deposition of organic liquid coating material (see
EN 12581:2005+A1:2010);
— horizontal plating lines (e.g. printed circuit board, etching, reel to reel, continuous plating lines);
— machinery for surface cleaning and surface pre-treatment of industrial items using liquids or
vapours (EN 12921-1:2005+A1:2010, EN 12921-2:2005+A1:2008, EN 12921-3:2005+A1:2008,
EN 12921-4:2005+A1:2008).
NOTE Machinery for surface cleaning and surface pre-treatment (see EN 12921 series) could be part of a
plating line.
