4 Requirements
The tolerances shall apply for a temperature of 23 o C ± 5 o C (73 o F ± 9 o F), unless otherwise indicated.
4.1 General Compliance with the requirements for flammability, durability, cosmetic, refractive, and transmittance properties specified herein shall be determined by the manufacturer using an appropriate statistically significant sampling procedure at an appropriate stage of manufacture. The samples and sampling procedure may be independent from those related to auditing for determining compliance with impact-resistance requirements. Representative samples of lens materials may be used to determine compliance with the requirements for transmittance properties. Compliance with impact-resistance requirements specified herein shall be determined in accordance with the sampling procedure given in 3.1 .
4.2 Impact resistance All lenses shall conform to the impact resistance requirements of the Code of Federal Regulations, Title 21 Part 801.41 0 (21 CFR 801 .41 0). The impact test of 21 CFR 801 .41 0 is described in 5.1. Plastic and laminated lenses may be certified by the manufacturer as conforming to the statistically significant sampling as described in 21 CFR 801 .41 0. All monolithic (not laminated) glass lenses shall be treated to be resistant to impact. NOTE – Federal policy exempts supplemental sunglasses (also known as clip-ons) from requirements of 21 CFR 801 .41 0, provided that they are intended to be worn over impact-resistant prescription eyewear, are not able to be worn independently, and are designed to be the same size or smaller than the impact-resistant lenses.
4.3 Flammability Flammability testing shall be performed in accordance with the procedures specified in 5.3. Compliance with flammability requirements shall be determined by the manufacturer for each type of material when first used, or when change is made in any coatings used on the material. This applies to plastic frames, plastic lenses, or the assembled product.
4.4 Frame finish The surface finish of metal and plastic frames shall be free of significant imperfections or roughness. All hardware or other components shall be free of burrs or hazardous projections. Excessive polishing compounds or other processing residue shall not be present. The surface finish of plastic frames shall be free of significant imperfections or roughness. All hardware or other metal components shall be free of burrs, and all exposed metal parts shall be corrosion resistant as defined in 4.5.
4.5 Frame corrosion Metal frames shall be manufactured of materials that of themselves provide corrosion resistance for their intended functional and cosmetic purposes under usual environmental conditions. Other materials may be used, provided they are surface coated with one or more layers of coating that provide corrosion resistance. Corrosion resistance of metal parts shall be sufficient to pass the test method described in 5.4. Frames with movable hinges shall move as designed after being subjected to test conditions.
4.6 Frame material safety to health of wearer Sunglasses shall be designed and manufactured in such a way that when used under the conditions and for the purposes intended, they will not compromise the health and safety of the wearer. The risks posed by substances, such as nickel, leaking from the device that may come into prolonged contact with the skin shall be reduced by the manufacturer to below any regulatory limit. Special attention shall be given to substances that are allergenic, carcinogenic, mutagenic, or toxic to reproduction. NOTE – Reactions may be generated by excessive pressure due to a poor fit on the face, chemical irritation, or allergy. Rare or idiosyncratic reactions may occur to any material and may indicate the need for the individual to avoid particular materials.
4.7 Frame deformation and retention of lenses When tested in accordance with the procedure described in ISO 1 231 1 Section 9.6, the frame fitted with lenses shall not:
