If the requirements given in this European Standard are to be applied to glass-lined apparatus and components, this shall be stated as follows when ordering: Prepared in accordance with EN 15159-1.
Requirements differing from those stated in this European Standard may be agreed upon between the parties at the time of ordering.
3.4 Defects 3.4.1 General Defects shall be examined visually (see 4.2). 3.4.2 Defects unacceptable in the finished product Defects unacceptable in the finished product are those, which render the components unusable. Such defects are typically as follows: a) Defects which cannot be repaired by the means described in clause 6 such as: defects extending over an area with a diameter > 8 mm; defects on inaccessible spots; defects concerning vessels and columns as described in 3.4.4; b) Collapsed lines in the cover coat; c) Bubble lines, i.e. fused-in bubbles arranged in a distinct line; d) Fused strain lines recognized as lines with colours different from the surrounding enamel; e) Areas not properly fused (a rough surface as being sandblasted); f) Devitrified areas in vitreous enamel or over crystallized areas in semi-crystallized enamel (recognized as a dull or a rough surface); g) Pull-through of ground coat (recognized e.g. as spot-like discolorations); h) Cracks, detected e.g. by a statiflux test; i) Spots with a diameter > 30 mm caused by grinding and polishing during the removal of impurities (see also 3.4.3 and 6.2). 3.4.3 Repairable defects Repairable defects are imperfections in the enamel coating, which allow under certain circumstances (see clause 3), further use of glass-lined equipment after repair. Common repairable defects are:
a) depressions with a depth exceeding 25 % of the coating thickness;

c) seal areas (gasket bearing surfaces) shall not be repaired by plugging. 3.4.5 Accessories Accessories such as agitators, baffles, thermo pipes, probes, inlet pipes, washers, manhole covers and dip-pipes shall not be repaired by plugging (see 6.1). 3.4.6 Fittings and pump components Fittings and pump components shall not be repaired by plugging (see 6.1). 3.5 Coating thickness The thickness of enamel coatings on steel substrates shall range from 1,0 mm to 2,2 mm, with the following exceptions:
a) maximum values may be exceeded by 0,2 mm on concave surfaces; b) enamel coating may be 0,2 mm thinner than the specified minimum values in limited areas and on convex surfaces; c) coatings on small parts with very small radii ≤ 5 mm, such as valve-stems or rotors of pumps shall have a minimum thickness of 0,6 mm.
Any changes in thickness shall be smooth. 3.6 General tolerances General tolerances and tests for the concentricity of agitators (see 4.7.1 and 4.7.2) shall be agreed upon between the parties.
NOTE Examples of tolerances for vessels, agitator vessels and columns are given in DIN 28005-2 [2],
DIN 28006-2 [3] and DIN 28007-2 [4], respectively. DIN 28159 [5] gives tolerances for agitator ends and DIN 2873 [6]
gives angular misalignments of flange surfaces. 3.7 Finish Unless otherwise agreed, non-enamelled surfaces, except for those which are not to be coated, such as fitting surfaces, shall be protected by a primer. Details shall be agreed upon between the parties at the time of ordering. Corrosion protection of parts without primer, e.g. connecting elements, shall be agreed upon between the parties at the time of ordering.
