Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 14214-2003 "Spectacle frames - General
requirements and test methods". Compared with GB/T 14214-2003, the main
technical changes of this Standard are as follows:
- Delete tensile properties from mechanical stability (see 5.7.1 of the 2003
edition);
- CHANGE "Plating adhesion" to "Adhesion of coating layer" (see 4.7.2; 5.8.1
of the 2003 edition);
- ADD test methods for materials other than metallic materials (see 8.5);
- Modify the test conditions for resistance to perspiration: The lowest part of
the sample is 15 mm ± 3 mm above the solution, which is changed to not
less than 12 mm (see 8.4.2.1; 9.7.2.1 of the 2003 edition);
- ADD the requirements for nickel release and corresponding test method
(see 4.2.2 and 5.2);
- ADD the requirements for resistance to optical radiation and corresponding
test method (see 4.10 and 8.9).
This Standard uses the redraft law to modify and adopt ISO 12870:2016
"Ophthalmic optics - Spectacle frames - Requirements and test methods".
Compared with ISO 12870:2016, this Standard has a lot of adjustments in
structure. Annex A lists the comparison table for clause-subclause number of
this Standard and ISO 12870:2016.
The main technical differences between this Standard and ISO 12870:2016 and

adopts the international standard (see 4.2.2);
 Delete ISO 8596 and ISO 11380;
- ADD terms and definitions "metal frame", "plastic frame", "boxed
measurement system", "boxed center", "distance between centre",
"horizontal boxed lens size", "distance between lenses", and "overall length
of side" (see 3.4 to 3.11);
- ADD "4.7.2 Adhesion of coating layer" requirement and "8.5 Adhesion of
coating layer" test method;
- Unify the material used for rimless and semi-rimless frames in 6.1.1 "test
lens" and modify it to "resin material";
- In Table 1, add the provision that "The subclauses with which compliance
