During the inspection of powder-coated surfaces on aluminium steel and galvanised steel, the following assessment criteria should be used:

  • the visual checks of the decorative appearance of the surface and the

    homogeneity of colour and texture are made without auxiliary means

    • Assessment distance = 3m for building components in interior areas
    • Assessment distance = 5m for building components in exterior areas
  • Substrate unevenness due to e.g. ghost lines, weld seams, unevenness caused

    by half-drawing (dents), drawing lines, impression etc. are admissible or

    conditionally admissible unless finishing grinding has been agreed.

  • Colour deviations and different degrees of gloss are conditionally

    admissible for surfaces with higher or conventional requirements, if they are

    not striking

  • Dimpled skin is conditionally admissible on surfaces with high requirements

    (if finely textured or also if coarsely textured, if the layer thickness >

    120µm according to constructive or order-related requirements) on surfaces with

    conventional and low requirements.

  • Inclusions, craters and bubbles are conditionally admissible if they do not

    exceed the numbers defined in the VFF-bulletins St.02 and Al.02.

Also compare the assessment criteria of the Verband der Fenster- und Fassadenhersteller e.v., VFF-bulletin St.02 (April 1997) and VFF-bulletin Al.02 (October 1997).
