6.0 ACCEPTANCE CRITERIA (GOST 17769-83)
6.1 Checking of external appearance
6.1.1

Checking of external appearance to determine the presence of surface
defects and design defects (failure to carry out special elements, for
example grooves, threads, bends and others), its quantity and dimensions.

6.1.2

While checking external appearance, parts are differentiated into critical,
medium and non-critical defects. Critical defects – cracks stress and folds
in the place of changing cross-section of parts. Medium defects –
expanded bubbles, stamping cracks and damage of thread Diameter, if its
quantity and dimensions exceeds the permissible norms and design
defects. Other defects are related to Non critical defects.

6.1.3

Checking plan for external appearance – single-stage. Checking level and
values of accepting level defects are given in table-16.

Geometric parameters (dimensions, tolerance forms and surface
roughness) should be checked after completion of checking of external

appearance as per point 6.1

6.2.2

The first fifteen components punched by the press tool is subjected to
100% inspection as per the component drawing, If found OK the press
tool is cleared for further production activities.

6.2.3

While checking geometric parameters, parts are differentiated as Basic and
Second-stage parameters.
Basic parameters – Diameter of the hole and external diameter
Second stage parameters – Rest of all

6.3 Checking of mechanical properties
6.3.1

Mechanical properties are checked by testing the withstand-ability for
bending on mandrels or bars and the number of bends is not less than four.

During the mechanical property checks, parts are differentiated into
destructive and non-destructive checks.
Non-destructive checks – checking the spring properties of washer,
hardness of washer etc...
Destructive checks – Bend tests, and all other tests which make the part
useless for assigned functionality.

6.3.3

During the bend tests the samples are bent till the sides are parallel around
the mandrel or bar with a diameter equal to double the sheet thickness.

6.3.4

The rounding radius for jaws during bend tests is taken as five times the
sheet thickness.

6.3.5

Chemical composition analysis to be carried out and mentioned in the
quality certificates.

Where ever coating thickness to be checked, raw material of same
composition either flat or round are to be used for finding the actual
thickness of coating by measuring it before and after coating. Following
test should be carried out on washers coatings.
Test for checking the thickness of coating (Gravimetric method,
X-ray fluorescent method and radiation method)
