3.1 film thickness distance between the surface of the film and the surface of the substrate
3.2 wet-film thickness thickness of a freshly applied wet coating material, measured immediately after application
3.3 dry-film thickness thickness of a coating remaining on the surface when the coating has hardened
3.4 thickness of uncu red powder layer thickness of a freshly applied coating material in powder form, measured immediately alter application and before stoving
3.5 relevant surface area part of an object covered or to be covered by the coating and for which the coating is essential for serviceability and/or appearance
Note 1 to entry: Measurement of this property is only required for the extended evaluation of film thickness measurements; see Clause 7. k) and I).
3.6 test area representative part of the relevant surface area within which an agreed number of single measurements is made as a spot-check
Note I to entry: Measurement of this property is only required for the extended evaluation of film thickness measurements; see Clause 7. k) and I).
3.7 measurement area area over which a single measurement is made
Note 1 to entry: Measurement of this property is only required for the extended evaluation of film thickness measurements; see Clause 7. k) and 1).
3.8 minimum local film thickness lowest value of the local film thickness found on the relevant surface area of a particular test specimen
Note 1 to entry: Measurement of this property is only required for the extended evaluation of film thickness measurements; see Clause 7. k) and I).
3.9 maximum local film thickness highest value of the local film thickness found on the relevant surface area of a particular test specimen
Note 1 to entry: Measurement of this property is only required for the extended evaluation of film thickness measurements; see ciausel. k) and I).
3.10 mean film thickness arithmetic mean of all the individual dry-film thicknesses (3.3) in the test area or the result of a gravimetric determination of the thickness.BS EN ISO 2808 pdf free download.
