3.2.1.1 Description
Indentation test apparatus (see Figure 2) fitted with an indentor pin and a displacement transducer,
suitable for one or two measuring points. Instead of the transducer, a dial gauge may also be used. The
water bath, as specified in 3.2.2, shall be connected to the indentation test apparatus by means of a
secure and watertight connection running from the bed plate, as specified in 3.2.3, through the bath to
the base plate of the apparatus. The measuring pin of the displacement transducer shall not be located
more than 50 mm from the axis of the guide rod.
3.2.1.2 Loading weights
The indentation test apparatus shall be set up in such a way that first the preliminary force of (25 ± 1) N
then the main force of a further 500 N may be applied vertically and without impact to the surface of the
specimen. The apparatus shall be capable of maintaining the total test force of (525 ± 1) N constant
through out the test. Two ball bearings shall be used to ensure a minimum of friction in the guidance of
the indentor pin. With the exception of the ball bearings, all components shall have a clearance of at
least 1 mm from the guide rod.
