ISO 11418-7:2016 specifies the design, dimensions, material and requirements of screw-neck vials for pharmaceutical preparations. Screw-neck vials are applicable to primary packs used in direct contact with a drug.

It applies to colourless or amber glass vials made from borosilicate or soda-lime-silica glass, made from glass tubing and intended to be used in the packaging, storage or transportation of pharmaceutical products.

NOTE The potency, purity, stability and safety of a drug during its manufacture and storage can be strongly affected by the nature and performance of the primary pack.
