Comparative testing

Test comparisons are valuable as a quality measure for laboratories. The comparison can be between instruments and methods. Here you get a good forum for discussions to raise awareness about the important role of the laboratory.

Purpose

RISE offers the following tre different test comparisons; PFI mill, ISO Brightness and emission parameters for forest industrial wastewater.

PFI mill - long fiber and short fiber (in collaboration with PFI Instruments)

By participating and comparing your own values ​​for refining with a reference pulp, you know how well your own refiner is calibrated. The results can also be a complement to traceable calibration before applying for accreditation or certification.

Once a year, RISE sends out reference pulp to the participating laboratories for refinering, handmade sheets and testing. The results are processed and compiled at RISE. Everything is presented in a report where the whole is reported in relation to the respective laboratory's values. Diagrams are obtained for each parameter as well as tables with the other participants' results.

The reference pulp is taken in large quantities at one time. This provides an opportunity for a direct comparison with the previous round and a long-term history.

ISO Brightness

The whole method will be tested and this is a good opportunity to easily compare the results from your own measurement with others' results. We will send out two pulps, a hardwood and a softwood. The results are sent to RISE and for compilation, including our own, and the participants are provided with the measurement results. In the compilation, the samples are deidentified so that each participant only knows his result but can compare himself with the other participants' results.

 

Emission parameters for forest industrial wastewater

Twice a year, May and November, we will send out frozen samples to you. A written summary is received a few months later where the results are presented anonymously. There are two content levels of each analysis. Report the analyzes that are of interest to you.

If there is a request for test rings, please contact us and we can discuss the possibility of starting them up.

You can also find us at EPTIS.

Method

PFI-mill:

Refinery with 5 points (ISO 5264-2)
• SR (ISO 5267-1)
• CSF (ISO 5267-2)
• WRV (ISO 23714)
• Density (ISO 534)
• Tensile index (ISO 1924-3)
• Elongation (ISO 1924-3)
• TEA (ISO 1924-3)
• Burst strength (ISO 2758)
• s o k (ISO 9416)
• Air permeance Bendtsen (ISO 5636-3)
• Tear resistance (ISO 1974)

ISO Brightness: The laboratories manufacture their own laboratory sheets according to ISO 3688 and then the sheets are measured according to ISO 2470-1, ISO brightness.

Test comparison of emission parameters for forest industrial wastewater:

  • COD, TOC, Tot-N, Tot-P, suspended solids GF / A, conductivity, chlorate, sodium.
  • Coarse particles and fibers in wastewater (susp 70). Sample type: Fibers dissolved in water samples
  • pH. Sample type: Water sample
