Support and Advice

The Hohenstein Institute has always defined its own success by the market success of its clients.

To hold one's own in the face of competition, it is not enough to have reliable test results for products and services; a company also needs as much information as possible and to be involved in beneficial cooperations.

Here, thanks to our interdisciplinary expertise and excellent contacts within various sectors, we are able to provide specific advice and individual support over and above product testing.

PPE is professional or working clothing that has been made to meet special requirements and is designed to protect the wearer from various different risks. Testing Personal Protection Equipment (PPE) is an expanding part of the work of the Hohenstein Institute.
Expert reports
Disinfecting your hands is a key hygiene precaution, and not only in healthcare institutions and food processing businesses.
Hygiene management
The lack of colourfastness in textiles, as shown here, is a common cause for complaint and is therefore an important aspect of materials testing.
Use of materials
Measurement of compression using HOSY (HOheinstein SYstem) according RAL-GZ 387. The device is used to evaluate compression products. These must continually decrease in the direction of the body's centre in order to support the flow of blood back to the heart. The items to be measured are fastened to 20 opposing, paired clamps. The items are then stretched and the energy required for each test clamp pair is measured.
Minimum requirements
The fit and workmanship of clothing is checked by skilled clothing technicians.
Fit and workmanship
The Press Office serves not only the Hohenstein Institute but also the International OEKO-TEX(R) Association, the German Certification Association for Professional Textile Servicese and the Reserch Association of the German Textile Industry.
Production optimisation
The less the interaction between surface and liquid, the greater the contact-angle (wetting-angle) is. At contact-angles smaller than 90° the surface is described as hydrophilic (water loving), at contact-angles between 90° and 130° it is described as hydrophobic (water-repellent). At angles larger than 130° the surface is called super-hydrophobic (extremely water-repellent) and the drops stay at the surface as nearly perfect balls.
Quality optimisation
The Beilstein test is used to detect chlorine halogen compounds. An annealed copper wire is dipped in the substance to be investigated and held in the non-luminous part of the flame of a Bunsen burner. If there are chlorine halogen compounds present, the flame burns green or blue.
REACh
In the anti-mite mattress textile flexible heating elements create hygrothermal conditions which prevent house dust mites from setting up residence.
Technology transfer
The presence of a number of harmful substances such as banned AZO dyestuffs can be verified using gas chromatography.
Marketability in line with customer requirements
Under UV Standard 801, the UV protection factor (UPF) is calculated in real-life conditions, i.e. including when the textile has been used and stretched.
Marketing
Testing the effect of commercial care treatments such as washing and drying on textiles (uniforms, T-shirts, blouses, shirts, businesswear) – loading of a tumble dryer
