ISO 15360-2:2015 specifies a method to estimate Stickies and Plastics in all grades of recycled pulp. It applies the principles for the separation of Stickies and Plastics described in ISO 15360‑1. The visualization and counting techniques described in ISO 15360‑1 are replaced here by image analysis. ISO 15360-2:2015 permits the use of different laboratory screening devices as well as screens of different sizes when applying the specified method. It is impracticable to define more closely the equipment or screen sizes to be used, because of the wide range of Stickies and Plastics found in recycled pulps, and the various screening devices which are being successfully used for their measurement. NOTE This method will only estimate those Stickies and Plastics which are tacky and which are retained on the screen of a given slit size under the temperature and pressure conditions of this test method. It is important to note that this will probably not be the total amount of Stickies and Plastics that are actually present in a given pulp sample.
Abstract
Overview - ISO 15360-2:2015 (Recycled pulps, Image analysis method)
ISO 15360-2:2015 specifies an image analysis method to estimate Stickies and Plastics in all grades of recycled pulp. It complements ISO 15360‑1 (visual method) by replacing manual visualization and counting with automated image detection and analysis. The method estimates tacky particles that are retained on a laboratory screen (commonly 100 μm or 150 μm slit aperture) under defined temperature and pressure conditions - it does not necessarily measure the total amount of all stickies/plastics present in a sample.
Key topics and technical requirements
- Principle: screening of disintegrated pulp, transfer of retained material to filter paper, marking/highlighting of Stickies and Plastics, and automated measurement by image analysis.
- Two marking methods for Stickies: metallic powder (white) or coating particles pulled from a special coated paper. Plastics are highlighted after dyeing and hiding Stickies with black silicon carbide.
- Image analyser system specs:
- Detects entire filter area (20 cm diameter or larger).
- Image detector (scanner or camera) with ≥256 grey levels and physical pixel resolution
