What is ISO 24117 about?
The international standard ISO 24117 provides you with a generic definition and classification of glass clarity to permit a global understanding of consumer quality requirements, with a corresponding method to measure glass clarity.
ISO 24117 establishes requirements for the use of the glass designations “clear glass” and “ultra-clear glass” for non-coloured glass items according to their clarity and iron content. ISO 24117 specifies a procedure for measuring the clarity of glass items by means of a spectrophotometer.
ISO 24117 covers mineral glasses, and glass items where a part is not covered by coating or decoration and is therefore available for sampling. ISO 24117 is applicable to the use of glass as tableware, giftware, jewellery and luminaries.
NOTES-
ISO 24117 is not applicable to the use of glass in the context of building, watches, containers, medicine and laboratories, and to other technical uses of glass.
