A pendulum friction tester shall be constructed , and shall comply with the following :
NOTE: An example of a friction tester is shown in Figure A 1.
(a) All bearings and working parts of the instrument shall be enclosed as much as practicable , and all materials shall be suitably treated to prevent corrosion under wet conditions.
(b) Wh en not in use on site , the apparatus shall be used and stored in a dust -free environment that is not subject to significant temperature variations.
(c) The pendulum friction apparatus shall be to ensure compliance with BS 7976-3 or CEN/ TS 16165. After the apparatus has been calibrated , regular internal checking shall be conducted on a set of control specimens and the results recorded. When results obtained from the control specimens vary from the values established following calibration by more than three units , the apparatus shall be partially or completely recalibrated.
NOTES: 1 Calibration may be arranged through a Sllitable accredited laboratory proficient in calibration and repair of friction apparatus. Australian laboratory accreditation authorities have traditionally expected that eqllipment be calibrated at intervals not exceeding two years. However , Sllbmissions for the extension of calibration intervals are considered on the basis of factors such as history of stability , frequency of use , required accuracy , ability of staff to perform in-house checks , internal laboratory eqllipment assurance programs , and successflll participation in proficiency testing programs
2 The control specimens should be stable with time and be of a range of surface rOllghness that are typical of the materials that the apparatus is used for measuring. New control specimens may benefit from having been sllbjected to an appropriate accelerated conditioning procedure. (d) The tester shall incorporate the following:
(i) A spring-loaded rubber slider of the mass , size and in Paragraph A5.2 , mounted on the end of the pendulum arm so that the sliding edge is 514 +3 mm from the axis of suspension.
