3 TESTING A SPECIMEN
To test a specimen, follow steps 1 to 7 below:
1. Place the indentation locating template on the specimen. Position
the template with respect to the test zone as shown in Figure 4 and
press down firmly against the specimen to hold the template in
place.
2. Hold the indenting tool angled as
shown and lower it onto the template,
supporting pins first,until the pins locate
in the two holes in the template.
3. Rotate the indenting tool very gently
until the bevelled disc touches the
surface of the specimen (Figure 5).
As soon as the disc touches the
specimen,start a stop watch.
4. After 30 seconds, rotate the
indenting tool away from the
surface of the specimen and
then lift it away completely
taking care not to dislodge
the template from its position
on the specimen.
