ISO594-1 Fig 3b RING GAGE FOR MALE LUER CONNECTORS
ISO594/1 Fig 3a or Fig 3b RING GAGE FOR MALE LUER CONNECTORS
ISO 594 Has Been Replaced
ISO 80369-7 Foreword
ISO 80369-7:2016 cancels and replaces the first edition ISO 594-1:1986 and the second edition of ISO 594-2:1998, clauses, subclauses, tables, figures, and annexes of which have been consolidated and technically revised. The new ISO 80369-7 specification does not define any gauges.
We still offer the ISO 594 Conical Ring Gages
Understanding that some companies may desire to test select parts against the obsolete ISO 594 specification; we have continued to make available the ISO 594/1 conical gages.
ISO 594 Gages Can Be Used For ISO 80369-7 Connectors
The ISO 594-1 Gauges can be used to test ISO 80369-7 parts; however, in doing so you are giving up some of the ISO 80369-7 product tolerance. ISO 80369-7 Connectors which pass testing with ISO 594/1 conical gages will pass testing with gages designed for ISO 80369-7; however, connectors which pass testing with gages designed for ISO 80369-7 may fail testing when tested with ISO 594-1 conical gages. The authors of ISO 80369-7 have made slight changes to the Luer cones which slightly increased their size. The ISO 594 Luer cones fall within the sizes of the ISO 80369-7 cones so that they are completely backward compatible.
