AS 2224.2:2009 pdf free download – Medicine measures
7.1 General
The measure (except for the teat of the dropper and the plunger seal) shall be constructed so that it exhibits no distortion, cracking, chipping, loss of clarity, staining or other defect likely to interfere with its normal use. When a clean measure is filled with water, its internal surface shall resist the formation and adherence of air bubbles. All parts of the measure shall be free from sharp edges, projections and roughness likely to cause accidental cutting, puncturing or abrasion of the skin of the user or which interfere with the reading or proper use of the measure. All edges shall be of a smooth finish. Additional constructional requirements, as appropriate to the type of measure under consideration, are specified in Clause 7.2 and 7.3.
7.2.1 Rigidity
Measures shall be sufficiently rigid over the temperature range of 5°C to 45°C to resist deformation (i.e. compressive forces) in normal use, i.e. manually filling to the mark and administration of its contents to the patient. NOTE: This requirement ensures accuracy of dosage and safe administration of the medicine under routine conditions experienced in Australia.
7.2.2 Stability
The base of the measure shall be constructed so that it shall stand on a flat surface without rocking or spinning. (See Clause 9.9).
7.2.3 Wall thickness
The wall thickness shall be uniform to within 10 percent of the mean wall thickness.
7.2.4 Pouring lip
If fitted, the pouring lip shall be so formed as to enable the contents of the measure to be ‘cleanly’ poured in a narrow stream without spilling and without any liquid running down the outside wall of the measure.
7.3.2.1 Integrity and sealing function
The teat shall be moulded in one piece. It shall be free from foreign matter, including mould-release agents and moulding flash, so as to not cause contamination of contents of the dropper by loose surface particles or by particulate matter produced by degradation of the teat. The lip of the teat shall be constructed so that it maintains intimate contact with the upper part of the body of the dropper rendering the system airtight and preventing accidental separation from the body in normal use.
7.3.2.2 Elasticity and capacity
The teat of a dropper type measure shall be of such an elasticity and capacity that it can be fully compressed without undue manual pressure and will draw up sufficient liquid to fill the body of the measure to the highest graduation mark in the one action—it shall not draw up more liquid than the body can hold as this results in contamination of the teat/body interface which is generally difficult to clean and dry.
