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.

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. moisture; volume flow optional according to customer requirements

System PK-GS (glass)

  • interior volume 100 l and 225 l
  • digital display and recording of test parameters temperature and rel. 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 % rH)
  • air renewal                             (/h):           0,5 … 1,5       
  • flow velocity                          (m/s):        0,1 … 0,5          

Applications

  • VOC and formaldehyde emission testing according to national and international 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 2-10 bar
  • 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-ES 60 (stainless steel)

  • more flexible, more modular; installation expandable
  • gas-proof double-walled test chamber with an electrically polished 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 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 (± 0,5 K)
  • 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"

System gama (stainless steel)

  • setup with one test chamber unit
  • gas-proof double walled test chamber with interior volume of (4000 ± 200) ml
  • casing temperature control of the test chamber air to 60 °C (± 0,5 K)
  • data display of temperature, pressure and the regulated air volume flow; valve switching automatically by magnetic valves
  • 5 pairs of gas wash bottles plus accessories for the absorption of formaldehyde into auqeous solution released by the testd samples

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
