What is ISO 2810 about?
ISO 2810 discusses paints and varnishes. ISO 2810 focuses on the natural weathering of paint coatings. ISO 2810 offers assessment criteria for weathering that occurs due to exposure. ISO 2810 specifies the conditions to take into consideration when selecting the type of natural weathering and the natural weathering procedure to determine the resistance of coatings or coating systems (direct weathering or weathering behind window glass).
Natural weathering is used to determine the resistance of coatings or coating systems (denoted in ISO 2810 by coatings) to the sun's radiation and the atmosphere.
Note: ISO 2810 does not take into account special atmospheric influences, for example, industrial pollution.
Who is ISO 2810 for?
ISO 2810 on natural weathering of paint coatings is useful for:
- Paint manufacturers
- Painters
- Paint and varnish retailers/suppliers
- Real estate developers/builders
- Quality control personnel
Why should you use ISO 2810?
Paints and varnishes are valued for their longevity. Paint coatings that are unable to stand the test of time are considered inferior quality products. The factor that affects the longevity of paints the most, is natural weathering.
ISO 2810 informs you about all the necessary apparatus, testing conditions and procedures to carry out the test without any missteps. ISO 2810 helps you to test the performance of your paint coatings by recreating the natural weathering effect and accelerating the process, to determine the results faster. ISO 2810 applies to external and internal paint coatings.
This method in ISO 2810 helps to determine the performance of paint coatings in field conditions, which helps in the quality control process as well as new product development.
What’s changed since the last update?
BS EN ISO 2810:2020 cancels and replaces the second edition (ISO 2810:2004), which has been technically revised. The main changes compared to the previous edition are as follows:
- In Clause 4, the list in b) has been amended by radiant exposure and temperature
- The time of wetness has been deleted from the list of additional observations on climate in A.2 and replaced by a note with the reference to ASTM Practice G84
- The climate classification in Annex B has been updated to ISO 877‑1:2009
- The text has been editorially revised and the normative references have been updated
