Standards Australia/Standards New Zealand
Supersedes: AS/NZS ISO 8980.3:2011 Ophthalmic optics - Uncut finished spectacle lenses, Part 3: Transmittance specifications and test methods
Draft Designation: DR AS/NZS ISO 8980.3:2014The objective of this Standard is to specify the requirements for the transmittance properties of uncut finished spectacle lenses.
This Standard is identical with, and has been reproduced from, ISO 8980-3:2013, Ophthalmic optics—
Uncut finished spectacle lenses, Part 3: Transmittance specifications and test methods.
As this Standard is reproduced from an International Standard, the following applies:
(a) In the source text ‘this part of ISO 8980’ should read ‘this Australian/New Zealand Standard’. (b) A full point substitutes for a comma when referring to a decimal marker.
References to International Standards should be replaced by references to Australian or Australian/New Zealand Standards, as follows:
ISO 13666 Ophthalmic optics—Spectacle lenses—Vocabulary // AS/NZS ISO 13666 Ophthalmic optics-Spectacle lenses— Vocabulary
ISO 14889 Ophthalmic optics—Spectacle lenses—Fundamental requirements for uncut finished lenses // AS/NZS ISO 14889 Ophthalmic optics—Spectacle lenses—Fundamental requirements for uncut finished lenses
Only normative references that have been adopted as Australian or Australian/New Zealand Standard have been listed.
The terms ‘normative’ and ‘informative’ have been used in this Standard to define the application of the annexes to which they apply. A ‘normative’ annex is an integral part of a Standard, whereas an ‘informative’ annex is only for information and guidance.
