What is ISO 20819‑1 - Wood-plastic recycled composites about?
ISO 20819‑1 is the first part of an international multi-series standard that covers the specification for plastics.
ISO 20819‑1 specifies the types and proportions of raw materials to be used for wood-plastic recycled composites (hereafter referred to as WPRC). It also specifies the health and safety requirements for WPRC and the methods to test the properties.
ISO 20819‑1 gives technical specifications such as terms, definitions, recycled material content, raw materials, raw material proportions, classification, test methods, and labelling for wood-plastics recycled composites (WPRC).
Note: ISO 20819‑1 is applicable to WPRC which are primarily used as building materials.
Who is ISO 20819‑1 - Wood-plastic recycled composites for?
ISO 20819‑1 on wood-plastic recycled composites is useful for:
- Manufacturer and suppliers of wood-plastic composites
- Construction of the building
- Test houses/ laboratories
- Plastics factory
Why should you use ISO 20819‑1 - Wood-plastic recycled composites?
A healthy environment is always possible by recycling plastic products. The recycling process of wood helps in reducing deforestation that results in saving the environment.
ISO 20819‑1 helps in verifying and classifying the raw materials used for wood-plastic recycled composites (WPRC). The formulas mentioned in ISO 20819‑1 are useful in calculating the recycled material content of wood-plastic recycled composites (WPRC).
ISO 20819‑1 helps you ensure safety as it removes the toxic substance used in wood-plastic composites while performing the test methods. ISO 20819‑1 helps you determine the types and proportion of raw materials to be used for wood-plastic recycled composites (WPRC).
What’s changed since the last update?
BS ISO 20819‑1:2020 supersedes BS ISO 20819:2018, which is withdrawn. BS ISO 20819‑1:2020 includes some technical changes as follows:
- The condition of method B (emission test chamber method) has been described more precisely
- The former Annex A has been divided into Annexes A and B
