ISO 9100 covers vacuum lug finishes. ISO, or the International Organization for Standardization, standards ensure that products will work together no matter what country they are manufactured in.
What It Covers
ISO standard 9100 is a written standard for types of vacuum lug finishes for glass containers. The ISO is split into sections, each dealing with a particular type and size of lug to fit certain glass containers.
ISO 9100 was written and published in 2005. It is available for download on the ISO website for a fee.
Vacuum lugs are seals that create a vacuum in the container they are pressed or rotated onto. Standardizing these vacuum lugs means easier and more secure fitting and a wider distribution potential for manufacturers, especially in conjunction with ISO standard glass container specifications.
