JSP eye and face protection products undergo strict testing to ensure they meet high performance and safety standards. Testing takes place in JSP’s advanced QA laboratories, located on-site at each manufacturing facility. Every batch of products is sampled, unpacked, inspected and tested against the specific requirements of the relevant standards for that model.

Light Transmission
Each lens is tested to ensure it allows the correct amount of light to pass through, according to the lens type and its intended use.

Optical Properties
Products are mounted on a headform, and a telescope instrument is used to measure spherical effect, astigmatism and prismatic effect. All values must meet the criteria for optical class 1 to ensure clear, undistorted vision.

Impact Resistance
Eye protection is subjected to different levels of impact testing using a 6mm steel ball fired at the lens:

F: 45m/s (100mph)

B: 120m/s (270mph)

A: 190m/s (425mph)

Large Dust Particles (Marking ‘4’)
Only applicable to goggles, this test places the product in a dust chamber where particles circulate and settle. After testing, the goggle is inspected for dust ingress.

Liquid Droplets and Splash (Marking ‘3’)
Goggles and faceshields marked ‘3’ are tested for protection against splashes. Goggles are fitted with test paper and sprayed with solution from all angles, while faceshields are assessed using a light beam test for coverage.

Molten Metal and Hot Solids (Marking ‘9’)
Applicable to goggles and faceshields, this test checks that molten aluminium or iron does not stick to the product and that a hot steel ball does not penetrate it within a set time.

Resistance to Fogging (Marking ‘N’)
Products are tested over a 50°C water tank with air circulation to simulate fogging conditions. The lens must remain fog-free for a minimum of 8 seconds to pass.

Ignitability
All products are tested for flammability by applying a steel rod heated to 650°C to the lens and frame to ensure they do not ignite or continue to burn.

Summary:

All eye and face protection is batch tested in JSP’s in-house QA labs

Lenses are checked for correct light transmission

Optical quality must meet optical class 1 standards

Products undergo impact testing based on F, B or A ratings

Marked products are tested for dust, splash, molten metal and fog resistance

All protectors are tested for ignitability at 650°C
