Central Analytical Laboratory
Central Analytical Laboratory at the Pulp and Paper Institute works in accordance with the accreditation requirements, applying continuous risk management:
1) Time working: 08:30 AM ÷ 16:30 PM;
2) Bacreticidal lamps turned on during the Laboratory outside opening hours;
3) Daily disinfection of surfaces in workrooms with solutions that do not disturb the environmental conditions;
4) Flexible working hours so that no more than two people work in one room.

In the Pulp and Paper Institute there is an ISO 17025 standardized Central Analytical Laboratory for analysis and testing of: fibrous material (pulp, semichemical pulp, mechanical pulp, secondary fibers from waste paper), all kinds of paper and board, paper and board packaging.
The Central Analytical Laboratory at the Institute is one of the four laboratories worldwide approved by IKEA for testing of corrugated board packaging materials.
Central Analytical Laboratory is a partner of Measurlabs
NEW OPPORTUNITIES AT THE CENTRAL ANALYTICAL LABORATORY
The Pulp and Paper Institute has instruments for determining the new containerboard properties set as criteria in the latest CEPI ContainerBoard classification (2022) – S-Test (ISO 7763:2024) and PPS Roughness (ISO 8791-4:2021).
The S-Test is an alternative to the slow CMT30 method for characterization of corrugating papers, especially those made from recovered paper, both low-weight and with a weight above 100 g/m2 up to 190 g/m2. The latter ones may also be dual-purpose papers, either liner or fluting. S-Tester measures the compressive/crushing strength in an S-shaped strip of paper up to 33,3 kN/m.
The Print Surf Tester is an instrument that determines the roughness of coated smooth papers – coated white kraftliner and coated white-top testliner. This instrument is also used to determine the roughness of newsprint and other types of smooth calendered papers – in the range of 0,5 micron to 8,0 micron. The measurement conditions are as close as possible to the compression applied to the paper during flexo or offset printing.
The instruments have been purchased within the implementation of a project No BG16RFPR001-1.003-0520-C01 for the provision of grant funding under the “COMPETITIVENESS AND INNOVATION IN ENTERPRISES” PROGRAMME 2021-2027, Procedure through selection of project proposals BG16RFPR001-1.003 “Introduction of Innovations in Enterprises”.
