What is ISO 15528 about?
ISO 15528 discusses paints, varnishes, and raw materials. ISO 15528 specifies procedures for the sampling of paints and varnishes, including coating powders, and raw materials used in their manufacture. Such products include liquids and materials which, without undergoing chemical modification, are capable of being liquefied when heated up, and powdered, granulated and pasty materials.
Samples can be taken from containers, for example, cans, drums, tanks, tank wagons or ships' tanks, as well as from barrels, sacks, big-bags, silos or silo wagons, or conveyor belts.
Note: ISO 15528 does not deal with the sample preparation for testing or reduction of the samples thus taken, which is dealt with in ISO 1513.
Who is ISO 15528 for?
ISO 15528 on paints, varnishes and raw materials for paints and varnishes (sampling) is useful for:
- Paint Manufacturers
- Quality control personnel
- Painters
Why should you use ISO 15528?
Sampling depends on the product and the size of the container but not on the type of product; for example, paint, varnish, coating powder, binder, pigment, extender, or solvent. Correct sampling forms the basis for the subsequent tests and their results. The various sampling procedures need to be carried out with great care by operators having the required knowledge and experience.
The general instructions in ISO 15528 supplement this knowledge and experience, and are applicable to most situations. The sampling method in ISO 15528 considers both the physical and the chemical characteristics of the material concerned. The samples of the product to be tested need to be taken in accordance with ISO 15528. The sampling procedure in ISO 15528 helps you do sampling accurately.
What’s changed since the last update?
BS EN ISO 15528:2020 supersedes BS EN ISO 15528:2013, which is withdrawn. BS EN ISO 15528:2020 includes some technical changes with respect to BS EN ISO 15528:2013. These include:
- Sampling of powder coatings from ISO 8130-9 has been included in the scope
- All information on sample dividing of coating powders originally in ISO 8130-9 has been deleted
- The text has been editorially revised, and the normative references have been updated
