IEC 60068-2-17:2023 deals with seal tests applicable to the external and internal detection in container sealing of gross leaks and fine leaks to determine the effectiveness of seals of specimens. For further tests to verify the ability of enclosures, covers and seals to maintain components and equipment in good working order, IEC 60068‑2‑18 can be helpful. This fifth edition cancels and replaces the fourth edition published in 1994. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) “Survey of sealing tests” has been deleted and the relevant content moved to a new Clause 4 “General”; b) the Scope has been revised; c) the figures have been updated for clarification purposes; d) all non-SI units have been removed; e) the information to be given in the relevant specification has been revised.
