Branca Idealair offers solutions for precision air conditioning of paper and paperboard

Paper and paperboard are strongly affected by their moisture content, BS EN 20187 and ISO 187 which changes according to relative humidity and temperature where they have been stored.

Before testing paper and paperboard, samples have to be conditioned inside an environmentally controlled laboratory with standard climatic conditions at 23 C with 50% of R.H.%. Paper and paperboard samples have to be brought to thermohygrometric equilibrium for a period of 24/48 hours as expressed by the norm ISO 187 .

Paper and paperboard must be conditioned in compliance with Standard ISO 187:

  • 23C 1C for temperature
  • 50% 2% for relative humidity

Other parameters have to be considered for specific test methods:

  • 21C 1C for temperature;
  • 65% 2% for relative humidity;

Temperature ( C) and relative humidity (%) inside the laboratories must have a loop data acquisition system as e.g. a datalogger in order to keep records of laboratory conditions under control for Quality System and continuously within tolerance limits 24/24 hours.

Thermohygrometric probes must have a measure accuracy lower than prescribed and data must be saved for inspection and QMS as e.g. ISO/IEC 17025 .

Branca Idealair manufactures climatic units in direct expansion or cooled-water with hydronic modules to condition paper, pulp and paperboard testing laboratories proposing ad-hoc solutions for technical consultancy, realization and units supply.
