VOC Emission Test Chambers

Volatile organic compounds (VOCs) are compounds that under normal conditions are emitted as gases from certain solids or liquids. VOCs cover a wide range of solvent using activities, e.g. printing, houshold surface cleaning, vehicle coating, furniture production, dry cleaning and manufacture of footwear and pharmaceutical products. Some of VOCs may have short- and long-term adverse health effects, thus it is very important to measure and control quantity of VOCs.

N-Wissen GmbH offers wide range of chambers for VOC and formaldehyde emission test according to ISO 16000-9, ASTM D6007-02, ASTM D5116, ASTM D6330, ASTM D6670-01, ASTM D7706-11, ASTM E1333, UNI CEN/TS 16516, GEV Testing Methods, EN 13419-1 and UNI 717-1 international standards.

All chambers can be designed and manufactured according to customer requirements.

Ozone Resistant Test Chamber

In operation the rubber materials deteriorate when exposed to ozone. Thus it is vey important to have test methods in which simple, accelerated time/exposure, comparisons of the material’s ability to resist cracking caused by ozone exposure can be empirically evaluated.

N-Wissen GmbH is glad to present the new Ozone Resistant Chamber OZT-QL-15040 for testing rubber materials and components according to the following standards:

  • ASTM D1149 – 18 “Standard Test Methods for Rubber Deterioration – Cracking in an Ozone Controlled Environment”
  • ISO 1431-3:2017 “Rubber, vulcanized or thermoplastic – Resistance to ozone cracking”
