Division BAT 26: In order to reduce total emissions of VOCs and to improve the overall environmental performance of coating of aircraft, BAT is to use technique (a) or both of the techniques given below.
United Kingdom
| Technique | Description | Applicability | |
|---|---|---|---|
| (a) | Enclosure | Component parts are coated in enclosed spray booths (see BAT 14 (b)). | Generally applicable. |
| (b) | Direct printing | Use of a printing device to directly print complex layouts on the aircraft parts. | Applicability may be restricted by technical considerations (e.g. accessibility of the applicator gantry, customised colours). |
Table 13
BAT-associated emission level (BAT-AEL) for total emissions of VOCs from the coating of aircraft
| Parameter | Unit | BAT-AEL(Yearly average) |
|---|---|---|
| Total VOC emissions as calculated by the solvent mass balance | kg VOCs per kg of solid mass input | 0,2–0,58 |
The associated monitoring is given in BAT 10.
