QUALITY
CONTROL
Overview:
We offer a range of quality control procedures from
visual inspection through to surface thickness testing,
cross hatch adhesion testing, and corrosion resistance
depending upon your particular requirements.
Visual
Inspection:
Visual inspection takes place at every stage of the
process from receipt of goods and unpacking through
pretreatment, coating, a dedicated inspection process
and packaging. The objective of visual inspection
is to spot bubbles, smears and other blemishes.
Surface
Thickness:
Dry surface thickness measurement of coatings can
be undertaken electronically with a surface thickness
probe capable of measuring surface thickness to
an accuracy of ±0.01µm.
Cross
Hatching:
Cross hatching the surface coating with 1mm squares
and checking for adhesion can be carried out using
statistical procedures for each batch.
Other
Mechanical Tests:
Other mechanical tests include the 6mm mandrel bend
to BS 3900 E1 which should result in no loss of adhesion,
an impact test to BS 3900 E7 and the pencil hardness
test.
Salt
Spray Testing:
Salt spray testing can be undertaken to determine
corrosion resistance to a scribed sample.
Other
Corrosion Tests:
Other corrosion tests include humidity to BS 3900
F9 and water soaking at 40 deg C, both for 1000
hours.
