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.

At Hohenstein, standardised test procedures provide information on whether the breathing comfort and filtering performance of everyday masks are adequate. © Hohenstein

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.

GenuTrace client advisory: Is your cotton supply chain UFLPA ready?

U.S. Customs and Border Protection has released updated operational guidance (CBP Publication No. 5560-0526) expanding its forced labor enforcement framework. The guidance supersedes the original 2022 UFLPA Operational Guidance and now covers all forced labor enforcement authorities — UFLPA, CAATSA, and WROs/Findings — in a single unified document. For cotton importers, the enforcement posture has not softened. It has become more structured, more documented, and more demanding. Learn more about UFLPA.

TERNAfil wins first place at PitchMiUp Night 2026 in Minden

The RWTH spin-off TERNAfil has developed MAXCarbon, a new high-performance hybrid fibre that combines the mechanical performance of carbon with the temperature and corrosion resistance of ceramic materials. For this development, TERNAfil was awarded first prize at the PitchMiUp Night in Minden on 21 May 2026.

Carbon-ceramic hybrid fibre proves its worth – NRW Minister for Science Mona Neubaur congratulates ITA start-up TERNAfil

MAXCarbon technology, a novel carbon-ceramic hybrid fibre developed by ITA spin-off TERNAfil, secured third place at the HIGH-TECH.NRW Demo Day on the TÜV NORD campus in Essen. The technology combines the strength of carbon fibres with the temperature and corrosion resistance of ceramic materials. Mona Neubaur, Minister for Science in North Rhine-Westphalia, congratulated the team on their success and on winning prize money of 4,000 euros.

“Production is a product”

From technical textiles and AI-driven robotics to the limitations of textile circularity: Professor Dr Thomas Gries looks back on more than two decades of development at ITA Aachen. In the interview, he explains why production technology remains a decisive success factor, discusses international collaborations and innovation ecosystems, and shares his views on the transformation of production landscapes and the challenges facing an increasingly regulated industry.

STOLL: Agreement signed for the divestiture of selected assets

In early 2025, KARL MAYER announced its strategic decision to focus on its core business areas of WARP KNITTING, WARP PREPARATION, and TECHNICAL TEXTILES. As part of this move, the flat knitting machine business under the STOLL brand was discontinued and the production site in Reutlingen was closed in October 2025.

DTF vs DTG Printing - The technologies shaping today’s custom merchandise market

From sportswear to branded tote bags, custom merchandise continues to grow in popularity across sectors, driving print shops to cater to short runs, personalisation, and rapid turnaround. As print providers look to this market, two printing technologies often stand out: Direct‑to‑Film (DTF) and Direct‑to‑Garment (DTG). Each offers its own benefits, and understanding these differences helps determine the most suitable production method for print service providers.
