Match existing wood properties, characteristics and manufacture when renewing or renovating wood or wood-based materials

This standard covers the skills and knowledge required to be able to identify and match quality, properties and characteristics of wood or wood-based materials. This involves identifying the wood that has been used and sourcing the same species or one with similar characteristics, structure and properties. To do this, you will need to understand how the structure and properties of wood affect the surface texture, grain characteristics, density, presence of extractives and overall look and also how it reacts to treatments and finishes.

This standard is suitable for anyone needing to match wood including those working in restoration or heritage.

---

1. comply with health and safety requirements and procedures at all times
2. identify species of wood or wood-based materials used in structures or products
3. analyse quality, properties and characteristics of wood or wood-based materials used in structures or products
4. review availability of wood with identical or similar composition to originals
5. work with others to identify available woods that will best match priorities where it is not possible for an exact match

19. regulations and codes of practice that you need to comply with when working with wood
20. appropriate equipment used to examine wood
21. how wood changes with time and how this affects the matching of wood of different ages
