Quality. Service. Perfection.

Shaping the future of mobility – that has always been ISP’s objective. Started 25 years ago as a service provider in the field of fuels and lubricants testing, the family-owned company quickly developed into an internationally renowned testing institute for engine, powertrain and vehicle tests as well as for laboratory analyses. Locations in Salzbergen (Germany), Grand-Couronne (France) and Shanghai (China) testify to the development partnership with the automotive and its supplier companies as well as the mineral oil and additive industry.

ISP’s DNA is characterised by value-creating growth and constant investment in sustainably innovative technologies. In addition to the classic business fields, ISP is also focusing on future technologies such as synthetic fuels, electrified drivetrains and hydrogen applications. With the new battery test centre in Salzbergen, the company not only supports battery manufacturers but also car manufacturers in the development and validation of battery modules and systems.

In this way, ISP and its 250 employees at all locations worldwide make an important contribution to sustainable mobility, consolidate its reputation as an excellent employer and business partner, and take responsibility for society and the environment.


Sustainable success based on both a strong commitment and deep sense of trust:

  • Maximum service and quality as the result of an owner-managed family business.
  • A continuous striving for perfection and precision right down to the smallest detail.
  • A fair and collaborative relationship with all employees and business partners.

ISP promotes this guiding culture at all levels and business areas of the company.
