Are users required to use only
products complying with ANSI Z87.1-2010?
No that's not the case. OSHA accepts the
three latest ANSI standards (1989, 2003 and 2010) as well as other standards
that the employer can demonstrate offers similar requirements, such as EN-166 or
CSA Z94.03-02. OSHA published this information on September 9, 2009 in the
Federal Register.
What are the principal changes in the
new standard?
The old standard has a section for each
type of protection, such as safety glasses, goggle, face shields and welding
helmets. Each type of protector had a chapter in the standard, which established
the required testing and optical properties as well as marking requirements.
The new standard is focused on the
hazards and is organized so that users can seek guidance by type pf
hazard, such as impact, optical radiation, splash, fine dust and mist.
What has changed in regards to
performance requirements?
The new standard has two
categories: Impact rated and non impact rated, while the old standard
had "basic" and "high impact" protectors.
According to Daniel Torgersen,
Chairman of the Z87 committee, the new coverage requirement is taken from CSA Z94.03.
Fewer impact tests are required:
down from 20 to 6. High velocity testing is still done at 150 feet/second.
Optional testing is now available
for dust and mist, as well as for UV (ultra violet), visible light and IR
(infra red) filters. These tests are not mandatory, but if a manufacture wants
to claim this specific performance the protectors must be tested and marked
accordingly.
Will the markings requirements change?
There are new markings requirements for
the optional testing described above. Splash and droplet protectors will be
marked D3-splash and droplet, D4-dust and D5-fine dust. Welding lenses shall be
marked W followed by shade number. UV protectors shall be marked U followed by
scale number. IR protectors shall be marked R followed by scale number. A
Visible Light filter (such as a gray lens for sun protection) shall be marked L
followed by a scale number.
Tables at the bottom of this page show the UV and
Visible Light transmittance requirements and the appropriate markings.
Z87+ will continue to indicate an Impact
protector
Z87 will now mean a Non-Impact protector.
Do Elvex eye and face protection
comply with the new Z87.1-2010?
All Elvex eye and face protection meet
the performance requirements of the new ANSI standard. As we move forward
markings will be added for the optional requirements, and markings will be
updated to comply with the new requirements. Packaging will be updated to
indicate compliance with the new standard.
ANSI Z87.1-2010
Below is a summary of the tests and
requirements for safety spectacles, goggle and face shields. Please note that
the original document is 47 pages long, and it contains a lot of detailed
information. This summary is not claimed to be complete.
|

resisting impact from a 6.35 mm (1/4 in) diameter steel ball traveling at a
velocity of 76.2 mps (250 fps). Spectacles shall be capable of resisting impact from a
6.35 mm (1/4 in) diameter steel ball traveling at a velocity of 45.7 mps
(150 fps).
For sample size of
6, no failure may occur (Z87.1-2003 required 20). |
|
Drop-Ball Impact |
Basic impact requirement for all devices: 1 inch diameter
steel ball dropped at 127 cm (50 inches) |
|

same as CSA Z94.03-02. No openings greater that 1.5 mm (0.06"). |

Spectacles shall be capable of resisting penetration from
a weighted projectile weighing 44.2 g (1.56 oz dropped from a height of
127 cm (50 in). |
|

any direction. Vertical and horizontal prism imbalance shall not exceed
1/4 prism diopter.... |
|
Refractive Power and Astigmatism |
The refractive power in any
meridian shall not exceed 0.06 diopter. The astigmatism shall not exceed
0.06 diopter.
No requirement for face
shields |
|
Haze |
Lenses shall not exhibit more than 3% haze, when tested
in accordance with.... |
|
Optical Quality |
No striae, bubbles, waves or other visible defects that
would impair optical quality is allowed. |
|
Transmittance |
Clear and filter plano lenses
shall comply with table 9 or 10
of Z87.1. Special purpose lenses shall comply with Table 7 through 10. |
|
Cleanability |
After cleaning the function of the spectacles shall not
be impaired. |
|
Optional Tests |
There are optional tests for Welding lenses, UV lenses, IR lenses and VLT
filters. For goggles optional tests include Splash/Droplet, Dust and Fine
dust. |
|
Markings |
Impact protector (must
meet High mass Impact, High Velocity Impact and Penetration tests) shall be
marked Z87+
Non Impact Protector
(must meet all requirements, except impact requirements) shall be marked
Z87.
Frame components: All major components shall bear Manufacturers mark
and shall be marked "Z87"
Lens: Manufacturers mark, and
if applicable "S" for lenses with less than 85% visible light transmission.
This marking is in accordance with old Z87 when optional tests have not been
performed. New version marking listed below.
