Plumbing & Heating

Independent testing institute for elastomers in the sanitary and gas industries.
We qualify suppliers, ensure material quality and eliminate risks in series production and in the field.

Problem & risk

In der Sanitär- und Gasindustrie entscheidet die Elastomerqualität über Sicherheit, Hygiene und Haftung. Schon kleine Abweichungen im Material oder in der Verarbeitung können große Folgen haben. Unklare Spezifikationen, nicht vergleichbare Materialien oder fehlende unabhängige Prüfungen.

Leaks and field complaints

Delays in approvals and certifications

Audit risks and liability issues

Series errors due to fluctuating supplier quality

High costs due to returns, replacement campaigns or delivery stoppages

We ensure that these risks do not arise in the first place.
