ISO 21882:2019(E)

Introduction
In the last few years, following the more and more urgent request for ready for filling containers,
packaging manufacturers managed to offer to the pharmaceutical industry containers already washed
and sterilized. This category of products was born about 30 years ago with the appearance on the
market of ready for filling syringes.
Only recently, the sterilized sub-assembled ready for filling syringes have been standardized by
ISO 11040-4 and ISO 11040-7, including the corresponding packaging system. These two International
Standards define the performance requirements of the glass syringes and the related test methods, as
well as the ready for filling packaging system for these syringes, also including the test methods.
ISO 8362-1 specifies the form, dimensions and capacities of bulkware glass vials.
Due to the increasing market presence of syringes ready for filling and the associated advantages of
this product for the pharmaceutical industry, the suppliers of packaging materials started to develop
systems of this type for vials.
The availability of two packaging configurations makes ready for filling glass vials suitable to be used
both in clinical trials and in mass production. Nest and tub configuration has been conceived to be used
usually with automated filling machines, while tray configuration is usually suitable for small batches
filled manually or by means of semi-automated filling machines.
This duality of packaging configurations calls for a standardization of the production processes,
materials quality and analytical methods when launching these products on the market, in order to
avoid conceiving too highly customized processes.
