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.
