Hohenstein tests and certifies FFP respiratory masks

BÖNNIGHEIM (ivs) The textile service provider Hohenstein has successfully extended its accreditations as a testing laboratory and certification body to include FFP (Filtering Face Pieces) respiratory masks in accordance with DIN EN 149, thus completing its portfolio in the textile mask sector. The necessary functional and safety tests on community masks, medical masks and FFP respiratory masks contribute to consumer safety.

In addition, Hohenstein has not only been a member of the German Mask Association since September 2021, which pools the expertise of all mask manufacturers and suppliers in Germany, but also supports the Quality Working Group with its expertise in the field of textile protective clothing.

Filtering Face Pieces are primarily used for the self-protection of the wearer and are intended to protect from harmful aerosols, particles and droplets. There are different protection levels for FFP respiratory masks (FFP 1-3), depending on how well they retain liquid and solid particles. In occupational safety, they are part of personal protective equipment (PPE) and fall under category III. Their protective function is specified throughout Europe by the DIN EN 149:2009-08 standard, which requires laboratory tests and practical performance tests with test persons. The Hohenstein testing laboratory carries out reliable proof of the safety of FFP respiratory masks in several test steps:

• Through visual inspection, the Hohenstein experts assess the correct labelling, the comprehensibility of the enclosed instructions for using the masks, as well as the functionality and packaging.

• Laboratory tests can determine, among other things, breathing resistance, filter medium transmittance and inward leakage. The practical performance of FFP respiratory masks is assessed through realistic tests with test persons.

• Test persons can also be employed to assess other parameters such as skin tolerance, field of vision or headgear comfort.

• Optional tests, such as testing FFP respiratory masks for harmful substances, complete the safety verification.

Since the beginning of the pandemic, a particularly large number of FFP respiratory masks with doubtful and even false labelling have been in circulation, so reliable and neutral testing and certification of these products is essential. Hohenstein, with its many years of extensive experience in the testing and certification of personal protective equipment, thus offers the ideal service for customers who value testing quality "Made in Germany".

As a testing laboratory for medical devices, Hohenstein also offers testing of medical face masks for their bacterial filtering performance, differential pressure as an indicator of breathing activity, microbiological purity and cytotoxicity, among others. Medical face masks fall under the Medical Devices Regulation 2017/745 and fulfil the requirements according to EN 14683. The testing service provider Hohenstein has already taken a big step towards safety and functionality with the introduction of its quality label for Tested Community Masks in June 2020 and also tests according to the first European Guideline for Everyday Masks, the CEN Workshop Agreement (CWA) 17553:2020.

A new standard to combat plastic waste in forests

With DIN SPEC 35808 “Tree Shelter for Forestry Applications,” the testing and research service provider Hohenstein, in collaboration with Rottenburg University of Forestry, as well as forestry authorities and industry partners, has established a clear framework for bio-based and fully biodegradable tree shelters. The pre-standard defines requirements and practical testing methods designed to reduce plastic waste in forests and strengthen the long-term protection of soil and the environment.

Hohenstein publishes 2025 Sustainability Report

The testing and research service provider Hohenstein has published its latest sustainability report, outlining key progress and strategic initiatives. The report focuses on ambitious CO₂ reduction targets, the company’s new mission statement and the systematic expansion of sustainable services for customers worldwide.

New DIN SPEC assesses environmental impact of textile fragments in soil

Textile products made from synthetic fibres, finished fabrics or dyed materials release fibre fragments into the environment at every stage of their life cycle. With the new DIN SPEC 19296, Hohenstein has developed a standardised testing method to analyse how these fragments behave in soil under natural conditions. Until now, little was known about their environmental behaviour or potential ecological effects once released.

An eco-friendly alternative to fluorocarbon treatments

Protective and outdoor clothing derives its durable water-, dirt- and oil- repellent properties from the application of fluorinated polymers or per- and polyfluorinated low-molecular- weight chemicals (PFCs). The beneficial properties thus achieved on textiles are offset by environmental and human health risks. For manufacturers of sports, medical, protective and automotive textiles, researchers at the Sächsisches Textilforschungsinstitut e.V. and the Leibniz Institute for Polymer Research have developed liquid-applied dispersions and solutions to functionalise textiles without the use of fluorine.

180 years of TESTEX: From Zurich silk testing to global certification

For 180 years, TESTEX has developed alongside the textile industry while maintaining the same underlying purpose: creating trust through independent and reliable measurement. Founded in Zurich in 1846 as the Zurich Silk Conditioning Institute, TESTEX has grown from a local institution serving the silk trade into an international Swiss testing and certification institute for textiles and leather.

Moving Advanced Recycling from Innovation to Implementation

The Advanced Recycling Conference 2026 explores technologies, markets, financing and scale-up of innovative recycling solutions for waste streams including mixed plastic waste, textiles and PVC. Europe’s chemical and materials sector faces growing pressure to close carbon loops, strengthen raw-material safety and resilience and meet increasingly ambitious EU recycling targets. Against this backdrop, the Advanced Recycling Conference (ARC) will bring together industry leaders, technology providers, researchers, innovators and policy-makers on 17–18 November 2026 in Cologne, Germany.
