This standard covers coating applications for vehicles regulated by Directive 2007/46/EC (superseding Directive 70/156/EEC) as amended from time to time. To ensure the relevance to current practice, coating applications for vehicles exempted from Directive 2007/46/EC and the refinishing of minor blemishes (spot repair) are also included in the scope of this standard.
Coating applications falling within the scope of this standard (including cleaning and pretreatment of the objects to be coated and cleaning of the tools and equipment) are defined as follows:
• The workshop at which the coating work is carried out does not generally require a permit under the German air pollution control legislation (see 4. BImSchV).
• To the extent such workshops exclusively undertake vehicle refinishing, they do not fall within the scope of the 31. BimSchV.
Note: OEM finishing outside the production line and the finishing of trailers fall within the scope of 31. BImSchV.
Further, it applies that
• air-drying or force-drying paints are used (object temperature ≤ 80 °C),
• coating application is essentially carried out manually, and
• there is no guided movement of the objects to be coated through the painting facility or parts thereof.
Coating application examples according to the vehicle categories defined in Directive 2007/46/EC are:
• refinishing of Category M, N, and O vehicles
• vehicle conversion and manufacture of superstuctures for Category M vehicles (ambulances, hearses, etc.)
• vehicle conversion and manufacture of superstuctures for Category N and O vehicles (luggage compartments, dumpers, trailers, tanks, add-on parts, etc.)
Examples of coating applications going beyond Directive 2007/46/EC include:
• manufacture and refinishing of agricultural and forestry machinery (as defined in EU Regulation No. 167/2013), piste grooming machines, rail-bound vehicles, and similar vehicles
• manufacture and refinishing of quad bikes, two and three-wheel motor vehicles (as defined in EU Regulation No. 168/2013)
• manufacture and refinishing of public service vehicles
A single paint shop will often cover combinations of the above coating applications.
If coating applications other than those covered by this VDI Standard are performed at the paint shop (e.g. an industrial coating applied in a vehicle refinishing shop) or the coating applications covered by this standard are performed in some other sector (e.g. automotive refinishing in an industrial coating plant) this standard applies to coating applications in those sub-areas that fall within its scope.
The same applies if the coating applications covered by this standard represent only part of the overall coating process (e.g. combinations of coating applications covered by the scope of this standard using electro-dip coating or powder coating technology).
At this point and in anticipation of the VOC emission control options described later, it should be noted that powder coatings are not technically feasible in the applications covered by this standard (temperature range ≤ 80 °C, chemistry of powder coatings).
The requirements of this standard can be used as an additional reference for installations subject to a permit under the German air pollution control legislation (see 4. BImSchV) provided that further statutory regulations are considered.
Emission control measures for production paint shops with a solvent consumption of > 15 t/a are described in VDI 3455.
VDI 4075 Part 2 provides an overview of ecological and economic optimisation options for coating activities.
