Rigorous inspection and testing procedures are key to ensuring that every product meets strict standards of quality. In-house test facilities at all JSP manufacturing sites enable verification of performance for each batch produced. Eye and face protection products are tested in the state-of-the-art QA laboratory. Samples are unpacked and inspected, then tested according to the performance criteria for each model.

Light transmission

Lenses are tested to ensure the light transmission value is within the range specified for each lens type.

Optical properties

Eye and face protectors are mounted on a test headform, and a telescope instrument is used to take readings for spherical effect, astigmatism and prismatic effect. Each of these values must be within limits assigned to optical class 1 lenses.

Impact resistance

For impact testing, eye protectors are mounted on a headform inside an enclosure and a 6mm steel ball is fired at the lens at varying speeds according to the marked performance level:

- Products marked F – impact tested at 45m/s (100mph)
- Products marked B – impact tested at 120m/s (270mph)
- Products marked A – impact tested at 190m/s (425mph)

Large dust particles

This test is only applicable to goggles with a ‘4’ marking. Goggles are mounted on a headform which is placed within a dust chamber. Dust is circulated within the chamber and allowed to settle before the sample is removed and inspected.

Liquid droplets and liquid splash

These tests are only applicable to goggles and faceshields marked ‘3’. Goggle samples are fitted with test paper to detect a spraying solution and mounted on a headform. Solution is sprayed on the goggle from all directions. The test paper is then removed from the goggle and inspected for detected solution.

Faceshields are tested to assess coverage. Samples are mounted on a headform and a light beam is directed at headform from various angles to ensure the light passes through the visor.

Molten metal and hot solids

This test is only applicable to goggles and faceshields marked ‘9’. Samples are tested with molten aluminium and molten iron that must not adhere to any part of the eye protector, and a hot solid steel ball that must not penetrate the eye protector in a specified time.

Resistance to fogging of oculars

This test is only applicable to eye and face protection products marked ‘N’. Samples are positioned above a tank of water heated to 50°C with a fan to circulate air around the sample lens. Transmittance is measured to ensure lenses remain free from fogging for a minimum of 8 seconds.

Ignitability

Ignitability testing is performed on all eye protectors. A steel rod is heated to 650°C and used to test the eye protector lens and frame.
