ASTM D1403 Test Methods for Cone Penetration of Lubricating Grease
ASTM D1403 Standard Test Methods for Cone Penetration of Lubricating Grease Using One-Quarter and One-Half Scale Cone Equipment
6. Apparatus
6.1 Penetrometer - An instrument similar to that shown in Fig. 1 of Test Methods D217, adapted for use with the 1/4-scale or 1/8-scale cone.
NOTE 1 - Any slight binding in the instrument may produce a significant error in penetration values. Periodic check of the release mechanism, cone dimensions, and weights of cone and its movable attachment is recommended.
6.2 1/4-Scale Cone and Shaft, as specified in Annex A1.1.
6.3 1/4-Scale Grease Worker, as specified in Annex A1.2.
6.4 1/2-Scale Cone and Shaft, as specified in Annex A1.3.
6.5 1/2-Scale Grease Worker, as specified in Annex A1.4.
6.6 Temperature Bath, either a water bath or an airbath, capable of regulating to 25 ± 0.5°C (77 ± 1°F) and designed to bring the assembled grease worker to test temperature conveniently. If a water bath is to be used for specimens for unworked penetration, means should be provided for protecting the grease surface from water and for maintaining the air above the specimen at test temperature.
NOTE 2 - A constant-temperature test room can also be used instead of the water or air bath.
6.7 Spatula, corrosion-resistant, having a stiff blade 13 mm (0.5 in.) wide and convenient in length.
