Plating piece
Surface of coating shall be free
from rust, burrs and exposed
bottom
Surface of coating shall be
smooth and flat, and there shall
be no defects such as blistering,
yellowing, speckle, burnt, cracks,
scratches and bruises
Spraying piece
Coating shall be free from
leakage and rust √
Coating shall be smooth and
uniform, with consistent color,

Surface is fine and there shall be
no defects such as cracks, burrs,
and black spots

Welded piece
Welding part shall be firm and
shall be free of de-soldering,
soldering, and welding
13
Uniform welds, no defects such
as burrs, sharp edges, splashes,
cracks
14 Other appearance
There shall be no burrs, cutting
edges and corners in parts that
touch human body or collect
objects
Use warpage measuring appliance of which precision is not less than 0.1mm.
Select a plate with the most serious warpage. Place appliance on diagonal of
the plate to measure. Take the maximum distance as measured value of
warpage.
5.3.2 Flatness
Use flatness measuring appliance of which precision is not less than 0.03mm.
Select three plates with the most serious unevenness. Measure distance from
reference line within a length of 0~150mm on surface. Take the maximum
distance as measured value of flatness.
5.3.3 Adjacent side perpendicularity
Use steel ruler or tape measure of which precision is not less than 1mm.
Measure lengths of two diagonals and opposite sides of a rectangular plate or
frame. Difference shall be measured value of adjacent side perpendicularity.
5.3.4 Dislocation
Use dislocation measuring appliance of which precision is not less than 0.1mm.
Select tested part with maximum distance between adjacent surfaces to
measure. Select any surface from this adjacent surface as measuring reference
surface. Place base surface of appliance on measuring reference surface.
Measuring surface of appliance measures another adjacent surface (along with
adjacent surface, measure one or more parts). When measured values are both
positive (or negative) values, take the maximum absolute value as measured
value of dislocation. When measured values are positive and negative, take
sum of maximum absolute values as measured value of dislocation and
maximum measured value as evaluated value of dislocation.
5.3.5 Splitting
Use feeler gauge to measure. Before measurement, it shall open and close
drawer or door three times to make drawer or door in closed position. Then
measure splitting value at 5mm inside splitting ends. Take the maximum value
as evaluated value of splitting.
5.3.6 Sag, swing degree
Use steel ruler or tape measure of which precision is not less than 1mm to
measure. Place steel ruler on horizontal and side surfaces adjacent to
measuring part of test piece. Extend test piece at 2/3 of total length. Measure
free sag of horizontal edge of drawer and left-right swinging value of drawer
side. Take maximum value as measured value of sag and swing degree.
