Frame Test
The frame, body, housing or headgear components are tested by installing "test" lenses that are strong enough to allow high mass and high velocity tests to be conducted. These components must have the integrity to comply with the tests regardless of the actual lens that will be in the model. The high velocity and high mass test methods are carried over from the 1989 Standard, but in the high velocity test, no failures are allowed. Spectacle frames intended to house prescription lenses shall meet the same criteria. Lateral coverage requirements have been increased to provide expanded rearward protection which primarily affects spectacles.
 
Frame Marking
All spectacle frames and temples, goggle bodies or housings, faceshield headgear and welding helmet components shall carry a permanent and legible mark or logo identifying the manufacturer. In addition, they are to be marked "Z87". Spectacle frames intended to hold prescription lenses are to be marked "Z87-2", and shall meet the requirements of Z80.5- 1997. For those products classified as having non-removable lenses, the product need carry only one marking. For spectacles, the Z87 (basic impact level) or Z87+ (high impact level) mark may be placed on the frame or temple. For goggles, faceshields or welding helmets, the Z87 or Z87+ mark may be applied to any component including the lens.
 
Lens Test
Personal eye protectors are classified, based on performance, as either basic or high impact models. They are to be tested as complete products as they will be offered to the user, and there is no distinction made based on whether the product has removable or nonremovable lenses. Basic impact models shall be capable of passing the 1 inch drop ball test and high impact models shall comply with high mass and high velocity impact criteria. The basic vs. high level impact requirements now fully apply to prescription spectacles. The penetration test continues to apply to plano plastic lenses, for all protectors, whether they are of the basic impact or high impact type.
 
Lens Marking
Removable lenses must be marked in a permanent and legible manner. All lenses must bear a mark or logo identifying the manufacturer. For spectacles with removable lenses, basic impact lenses require no additional mark related to Z87, but high impact lenses require a "+" mark indicating the elevated impact performance. For all other product categories, non-removable lenses, windows or filters require the manufacturer's mark or logo. The product need carry only one marking. Basic impact lenses shall be marked with "Z87" and high impact lenses shall be marked "Z87+". Special purpose lenses and photochromic lenses continue to carry "S" and "V" markings respectively
 
Optical Requirements
Optical requirements for plano spectacles are specified in the areas of refractive power, prismatic power and definition. Haze for lens components shall not exceed 3%. Transmittance requirements are specified for clear, tinted and shaded filter lenses and windows.
