2.3 Machine Settings at subsequent calibrations

Rotational speed of each of the outer pegs

(see note 1)

Lissajous figure dimensions

Face dimension of the specimen holder insert

Parallism of plate and abrading tables

(see note 2)

Maximum circumferential parallelism

(see note 2)

Combined total mass of specimen holder, spindle and

weight

NOTE 1

The machine should be checked over a period of 5 minutes using a stopwatch.

The counter should also be checked correctly to ensure it is functioning properly.

NOTE 2

Parallelism should be measured using a dial gauge clamped in turn to each specimen bearing housing

the machine should be switched on and the maximum and minimum readings taken from a dial gauge

for each station.

The circumferential parallelism of the test piece holder assembly when inserted into each station can

be checked by means of the appropriate feeler gauges.

2.4 Calibration Checks

If the SBT401 is being used on tests where end point is defined by a change in colour, then to ensure

that the machine is correctly set, start the machine using a specimen of plain dark pigment printed

fabric.

Proceed for 7000 cycles then examine the specimen for colour change. If this is not even then the

machine is not correctly set and the machine setting listed above should be checked. It is

recommended that this is checked regularly depending on usage.

If the laboratory is using broken ends or weight loss as the end point then two reference fabrics

relevant to the work of the laboratory should be used at frequent intervals conducting the full test to

the end point.

If uneven wear is suggested between the testing positions or between machines the settings should be

checked.
