AS 2224.2:2009 Medicine measures
9.8.1 Introduction
Although it is acknowledged that it is impossible to exhaustively test the resistance to all possible chemical agents with which the measure is likely to come into contact, the test described in Appendix Eutilizes reagents that are considered to provide representative properties of the range of agents likely to be encountered in the routine use of the measure.
9.8.2 Resistance to chemical agents
When a measure has been tested in accordance with Appendix E, it shall continue to meet the requirements of Clause 7.2 and its markings shall not exhibit any deterioration that affects their clarity or legibility with respect to its accuracy in subsequent use.
9.9 Stability
When filled to the uppermost graduation, a tumbler or conical measure shall remain upright and not topple over when the surface on which it stands is tilted at up to 15 degrees to the horizontal.
9.10 Effectiveness of seal and grip in dropper
When a fully assembled dropper is filled to maximum capacity with water and held, teat uppermost, by the teat at any angle from the upright position (see Figure 1) to up to 45° from the vertical (tip downwards), it shall not drip any of the contents for at least 30 seconds from the time of last contact with the surface of liquid in the supply container.
9.11 Resistance of teat to degradation by heat
After a teat has been subjected to continuous 24 h heating conditions in an oven preset at a minimum of 40°C, it shall continue to comply with the requirements of Clauses 4.2, 5.2(b) and 7.3.2.
9.12 Effectiveness of seal in plunger type measure
The plunger type measure, when fully assembled filled to maximum capacity with water and held vertically or up to 45° from the vertical, it shall not drip any of the contents for at least 30 seconds from the time of last contact with the surface of liquid in the supply container.
