Logo Belsana

Products of high quality certified regularly by independent testing institutes.

BELSANA compression and support stockings are made in Germany in line with the strictest standards of quality. The company is therefore certified according to DIN EN ISO 13485 and its products bear the CE mark. The medical compression stockings from BELSANA also comply with the strictest international quality and test provisions of RAL-GZ 387/1 and 2.

Refined quality management, coupled with the development of new top products and a first-class service for our customers, means that the company can grow on a firm and lasting basis.

The level of pressure exerted on the legs depends on the severity of the patient's condition: in principle, the greater the damage to the venous system is and the softer the connective tissue has become, the stronger and thicker the compression stockings must be.

The RAL-Norm distinguishes between four compression classes (Ccl.):

Compression class Compression Compression average in mmHg at measuring point cB
(the slimmest part of the lower leg)
Ccl. 1 slight 18 – 21 mmHg / 2,4 – 2,8 kPa
Ccl. 2 medium 23 – 32 mmHg / 3,1 – 4,3 kPa
Ccl. 3 firm 34 – 46 mmHg / 4,5 – 6,1 kPa
Ccl. 4 very firm 49 and more / 6,5 and more


RAL Quality Seal

Our medical compression stockings meet the standards of the RAL-Norm, the strictest norm worldwide for the production of medical compression stockings.

The RAL Quality Seal on the packaging of our medical compression stockings guarantees that our products meet this norm.

The RAL guidelines are set by the “Gütezeichengemeinschaft” who decides, in cooperation with the “German Society of Phlebology”, the standards (quality and technical specifications) required for the production of medical compression stockings.

The independent Hohenstein Research Institute carries out tests to verify the requirements set by RAL are met and principally on the basis of:

  • pressure gradation
  • fibre analysis
  • knitting structure
  • chemical analysis

Öko-Tex Standard 100

The Öko-Tex Standard 100 is a testing and certification system for textile products.
Öko-Tex Standard 100 guarantees that certified products observe strict limits on the use
of certain materials and dyes.

This certified standard applies to all BELSANA compression stockings.

CE compliance with European directives

The CE marking serves as a “passport” for the Single European Market and allows BELSANA products to circulate freely throughout the European market.

It indicates compliance with the requirements for medical products according to the European directive 93/42 EWG and the German law on medical products (MPG).

DIN EN ISO 9001 / DIN EN ISO 13485

Our products meet the highest quality standards and are produced according to the quality management system DIN EN ISO 9001 / DIN EN ISO 13485.

This certificate documents process oriented operations and the optimisation of in-house production structures. The continuous improvement of processes is guaranteed by regular external audits.
