Ejendals chemical permeation laboratory

Ejendals has invested in a first-class laboratory to serve you better when providing you with a safety glove that protects you from the hazardous effects of challenge chemicals.

Ejendals chemical labroratory supports a wide range of industries

Any employer who requires its employees to work with hazardous materials or in a potentially hazardous environment, such as those working in the healthcare, industrial chemical, manufacturing, cleanroom, and defence sectors, must provide personal protective equipment that complies with the PPE Regulation (EU) 2016/425.

Our job is to help companies ensure their employees safety

Every year our laboratory helps companies, based on their specific needs, to the very best hand protection. Because, choosing safety gloves that offer the best protection against chemicals can be complicated. The chosen gloves must prevent permeation and degradation to ensure personal safety. 

What is permeation and how is it measured?

Permeation is when a chemical passes through the glove material through molecular diffusion. This occurs even when there are no physical holes in the glove material. Permeation is measured by exposing the outer surface of a material sample to the chemical against which it is being measured.

What is degradation?

Degradation is the process by which the physical properties of the safety gloves change and are damaged after being exposed to chemicals.

What is “breakthrough time”?

The breakthrough time is the elapsed time between the material’s first exposure to the chemical and the permeation rate reaching a target value.

Ejendals automated permeation system

The automated systems speed up analysis time using new simultaneous testing methods to determine the glove material’s resistance to chemical permeation specified under EN 16523-1.
The optional automated challenge chemical introduction cells can test different challenge chemicals or hold the same chemical for multiple automated testing processes. In addition, the system offers us the flexibility to vary the test speed depending on a sample’s breakthrough time, which can range significantly from one minute to up to eight hours. This removes the need to wait for longer tests before obtaining complete results.

This kind of testing is a crucial step in achieving our vision - no injuries to hands and feet, says Bart Vervust, Chemical Compliance Manager at Ejendals

Quality assessments and product development

Ejendals chemical laboratory also plays an important role in the quality assessment of our products. Such as measuring pH values and levels of heavy metals in our products. Our highest priority is always to deliver well-tested, safe and certified products.

In addition to the chemical laboratory in Leksand, there is also a laboratory for mechanical tests, where we can perform abrasion tests, heat resistance, cut resistance and much more.
We also have a test laboratory located in Jokipii, Finland, where we develop, assess, and test our JALAS safety shoes.

Together Ejendals laboratories ensure that all TEGERA and JALAS products maintain quality of the highest order. Our labs also play an active role in our continued drive towards greater sustainability.
