ISO 90-3:2000 pdf download – Light gauge metal containers — Definitions and determination of dimensions and capacities — Part 3: Aerosol cans.
1 Scope This part of ISO 90 defines the diameters, apertures, constructions, shapes and capacities of round, aerosol cans. It specifies methods for determining diameters, gross lidded and brimful capacities. It also gives tolerances on capacity and recommends an international designation. NOTE A list of standards dealing with materials used for aerosol cans is given in the Bibliography. 2 Terms and definitions For the purposes of this part of ISO 90, the following terms and definitions apply. The figures given in this clause illustrate the terminology. 2.1 aerosol can rigid can made of light gauge metal with a maximum nominal material thickness of 0,49 mm; non-refillable can intended to contain a product which is dispensed by pre-stored pressure in a controlled manner through a valve 2.2 Heights 2.2.1 body height H 1 height of the body over the double seams (three piece aerosol cans only) See Figure 1 a). 2.2.2 overall height H 3 height of the unclosed container See Figures 1 a) and 1 b).
2.3 aperture circular opening designed to be sealed by a valve component of which the valve is located in a valve cup 2.4 Constructions 2.4.1 three-piece can can made from three main components: body, top end and bottom end See Figure 2.
2.6 Capacities 2.6.1 gross lidded capacity C 1 total capacity of a can, fitted with a valve, valve cup and dip tube NOTE Gross lidded capacity is expressed in millilitres. 2.6.2 brimful capacity C 2 total capacity of a can without a closure, determined according to 4.2 NOTE Brimful capacity is expressed in millilitres. 3 Determination of dimensions 3.1 Measurement of diameters 3.1.1 Measure the internal body diameter using a plug gauge or derive it from the external diameter. 3.1.2 Measure the external body diameter using a vernier calliper. 3.1.3 Measure the necked-in diameter using a plug gauge applied to the internal diameter of the extremity to which the end is to be fixed.
