Identify the variant being tested
Connect the card to the vehicle or job and selected formula variant. With several mixes, keep cups and cards clearly paired. An internal identifier can avoid exposing customer details on every sample.
Use current documentation for the actual coating system. The station name does not determine mixing ratios, application or drying.
Keep substrate and application traceable
PPG’s own spray-out SOP uses equipment and technique corresponding to the vehicle application. This illustrates comparability, not universal settings for every system.
Record relevant departures from the planned process. Otherwise a different substrate or application may be mistaken for a formula difference.
Check card positioning during preparation
Position the card as intended for the actual device. Clarify format and holder before mixing. A generated application photograph is not a mounting or operating instruction.
Separate prepared, freshly coated and already assessed cards. Clear status prevents confusion in the next stage.
Enable a clear later comparison
Record what was actually done and label the card. Later assessment can then refer to the same test. The colour-comparison article covers that separate stage.
The BUWO station supports a defined spray-out area. It does not prescribe a universal coat count, drying window or colour approval.
