Test Chamber Systems

The determination of formaldehyde and VOC emissions from wood-based materials, construction products and furniture is a core competence of the EPH for many years.

As accredited test body for emission testing, the EPH provides not only professional know-how but also technical equipment in terms of emission test chambers and gas analysis systems.  

These test systems are especially characterised by an easy operability and a layout adapted perfectly to customer`s needs as well as by an attractive price. Among others, the systems are established in the wood-based materials, binder- and furniture industry and at testing institutes. Emission testings can be conducted according to several test procedures.

We are pleased to support you in course of R&D or product surveillance, to validate your system by appropriate comparison tests and to train your laboratory staff.

Test equipment

Emission Test Chambers

System PK-ES (stainless steel)

  • Interior volume 100 l/225 l/1,0 m³
  • Electrically polished interior
  • Digital display and recording of test parameters (temperature and rel. air moisture, flow velocity, volume flow)
  • Automated control of the test parameters according to set value specification via PLC touch panel
  • Data output as CSV file for easy further processing e.g. Microsoft Excel®
  • Possibility of regulation/tracking of the testing process via the customer's internal intranet/web browser

System PK-GS (glass)

  • Interior volume 100 l and 225 l
  • Digital display and recording of test parameters temperature and rel. air moisture
  • Volume flow optional according to customer requirements

Standard test conditions

  • Temperature range                (°C):         +20 … +25        (± 0,5 K)
  • Desorption temperature       (°C):         +60   (max.)     
  • Relative humidity range         (% rH):      40 … 50          (± 3 %)
  • Air renewal                             (/h):           0,5 … 1,5      (± 0,05)       
  • Flow velocity                          (m/s):        0,1 … 0,5          

Applications

  • VOC and formaldehyde emission testing according to national and international norms and standards
  • Conditioning under defined climatic conditions

Requirements at site of installation

  • Air-conditioned at 18 °C to 20 °C without direct solar radiation
  • Compressed air supply with max. 10 bar output pressure
  • Sufficient floor load capacity and installation area

Gas Analysis Apparatus

Derived test procedure for the determination of formaldehyde emission of wood-based materials according to DIN EN ISO 12460-3 – gas analysis procedure (formerly DIN EN 717-2)

System GA-4-M.nt (Master)

  • More flexible, more modular; installation expandable
  • Gas-proof electrically polished double-walled test chamber with an interior volume of (4000 ± 200) ml
  • Temperature control of test chamber air regulated up to 60 °C (± 0,5 K)
  • Adjustable air volume flow of (60 ± 3) l/h
  • Digital data display of temperature, pressure, moisture and air volume flow; optional data recording and –output as CSV file according to customer needs
  • Valve switching manually or automatically by magnetic valves according to customer requirements
  • 5 pairs of gas wash bottles plus accessories for the absorption of formaldehyde into aqueous solution released by the tested samples

System GA-ES 120 (stainless steel)

  • Setup with one or two test chamber units
  • Gas-proof double walled test chamber with an interior volume of (4000 ± 200) ml
  • Casing temperature control of the test chamber air up to 120 °C
  • Adjustable air volume flow of (60 ± 3) l/h
  • Digital data display of temperature, pressure, moisture and air flow; optional data recording and –output as CSV file according to customer needs
  • Valve switching automatically by magnetic valves
  • 5 pairs of gas wash bottles plus accessories for the absorption of formaldehyde into aqueous solution released by the tested samples
  • Capable for tests for instance according to ÖNORM M 6219-1: “Requirements for public and commercial sauna installations, infrared cabins, steam and other warm chambers"

Applications

  • Use within the scope of self-surveillance for quality assurance of products in the production process
  • Accompanying investigations in course of product developments
  • For standard tests in testing institutes
  • Extended use possible, e.g. for orienting formaldehyde- and VOC emission testing under modified test parameters
