WHAT IS EN 14126?

PERFORMANCE REQUIREMENTS AND TESTS METHODS FOR PROTECTIVE CLOTHING AGAINST

INFECTIVE AGENTS

This standard establishes standards for re-usable and limited-use protective gear that protects against infectious pathogens, as well as test techniques. Protective clothing against infectious agents such as bacteria, viruses, and other microbes serves two purposes:

To keep infectious organisms away from the (potentially damaged) skin

To avoid the transfer of infectious agents to other individuals and situations, such as eating or drinking, when the person's protective clothes has been removed.

FOR MATERIALS TO COMPLY WITH EN14126 THEY MUST ALSO UNDERGO ADDITIONAL TESTING AS FOLLOWS

PENETRATION TEST USING SYNTHETIC BLOOD

This test identifies the pressurisation at which the infected synthetic blood penetrates the material. The higher the class the greater the protection of the fabric.

ISO 2261

RESISTANCE TO BIOLOGICALLY CONTAMINATED AEROSOL PENETRATION

The effect of the barrier against biologically contaminated aerosols is evaluated using this test. A bacterial solution is dispersed in an aerosol and sprayed on an unprotected cellulose nitrate membrane as well as one that has the test material on it. The bacterial load is determined by analysing both membranes, and the results are categorised based on the penetration ratio. The higher the class, the better the fabric's protection.

ISO 22610

RESISTANCE TO PENETRATION BY BACTERIA
This test superimposes a bacterial contaminated donor material on the test material and subjects it to mechanical rubbing. The results are recorded in accordance with breakthrough times i.e.: the point at which the bacteria penetrate the barrier material measured in minutes as highlighted in the table below. The longer the breakthrough time, the higher the class and therefore the greater the protection of the fibre

ISO 22612

ISO 22612 RESISTANCE TO CONTAMINATED DUST PENETRATION
A pre-sterilized material is placed in a testing device and contaminated talcum powder is applied (Bacillus Subtilis). While the substance is being shaken, an agar plate is placed underneath it. After the agar plate has been incubated, the particles that penetrate the material are analysed, and the findings are measured in penetration log units, as shown in the table below: The higher the class, the better the fabric's protection.

ISO 16604

RESISTANCE TO VIRUS PENETRATION

This test employs a liquid contaminated with a bacteriophage or virus (rather than synthetic blood) to determine the pressure at which the liquid penetrates the material.
