TEHAG qua­lity and service

Production standards and product certifications

We demand nothing less than the best when it comes to quality and service. This is true for every process, from con­sul­ting all the way to order pro­ces­sing, and in particular for every one of our products, which we consider to be our flagship. In order to achie­ve and main­tain this high level of quality in the long term, we have introduced a variety of standards and certifications for both our operative business and for our pro­ducts.

PRODUCTION STANDARDS

Every vehicle and every machine in which TEHAG products are used delivers op­ti­­mal performance every day and, de­pen­ding on the application in ques­tion, is ex­pos­ed to a variety of in­flu­en­ces and for­ces, sometimes 24 hours a day, 7 days a week. Top quality exhaust treatment sys­­tems are the only way to withstand these influences over the long term and keep malfunctions and downtime to a mini­mum.


Furthermore, we also comply with spe­cial requirements for production qua­lity for particularly sensitive ap­pli­ca­ti­ons in which TEHAG products are used. Our processes are certified in accordance with ISO 9001 and ISO 14001, which means they are standardized and de­sign­ed with sus­­tain­ability in mind. 

As a specialist welding company, our pro­duc­tion facilities are also certified in ac­cor­dan­ce with:

SVS Certification according to EN 15085

PRODUKT CERTIFICATIONS

Naturally, as the flagship for our com­pa­ny, our products are also certified and ap­­pro­­ved in accordance with the stric­test testing specifications. When it comes to using our particulate filter sys­tems to re­tro­fit vehicles and machinery, the cer­ti­fi­ca­tions listed below are an essential pre­re­qui­site. The ex­cel­lent results from the­se strict tests also allow us to verify our products’ extremely high quality and per­for­mance standards for our OEM cus­to­mers.
