Full title and description

STB BS ISO 4561-2023 — BS ISO 4561:2023 / ISO 4561:2023: "Wood raw parquets elements — Classification". This document is the British adoption (BS ISO) of the international standard that establishes the quality classification of raw parquet elements used in the manufacture of parquet strips and flooring components.

Abstract

This standard specifies the classification, by quality, of raw parquet elements intended for the manufacture of strips for different types of parquet floorings. It covers classification for specified wood species including oak, beech, birch, maple, fir and spruce, and gives the criteria for grading raw parquet elements for subsequent processing into flooring products.

Scope

The standard establishes a classification system, by quality, for raw parquet elements of specified wood species (oak, beech, birch, maple, fir and spruce). It is limited to raw parquet elements intended for manufacturing strips used in various types of parquet flooring and defines the quality grades and the criteria for assigning elements to those grades. The standard replaces older ISO documents that previously covered similar content.

Key topics and requirements

• Quality classification system for raw parquet elements (grading criteria and definitions).
• List of wood species covered: oak (Quercus sp.), beech (Fagus sylvatica sp.), birch (Betula sp.), maple (Acer sp.), fir (Abies sp.) and spruce (Picea sp.).
• Requirements and characteristics used to determine grade (visual defects, knots, sapwood/heartwood, splits and other relevant features used in classification).
• Alignment with international committee work (ISO/TC 218) and withdrawal/replacement of previous ISO standards on parquet raw elements.

Typical use and users

Primary users include parquet and wood flooring manufacturers, timber processors and suppliers of semi‑finished parquet blocks, quality control and inspection personnel, purchasing/specification teams in construction and flooring trade, conformity assessment bodies and national standards organizations that adopt or reference the ISO text. The standard is used to harmonize quality grading and procurement specifications for raw parquet elements.

Related standards

ISO 4561:2023 replaces earlier ISO documents on parquet raw elements (for example ISO 3398:1977, ISO 3399:1976 and ISO 5333:1978). It is part of the body of standards overseen by ISO/TC 218 (timber). National adoptions, including BS ISO 4561:2023, are published by national standards bodies such as BSI.

FAQ

Q: What is this standard?

A: ISO 4561:2023 (published nationally as BS ISO 4561:2023) is an international standard that specifies the quality classification for raw parquet elements used to manufacture parquet flooring strips.

Q: What does it cover?

A: It covers the classification (grading) criteria for raw parquet elements of specific wood species (oak, beech, birch, maple, fir and spruce) intended for producing parquet strips and flooring components. The standard defines quality grades and the features used to assign elements to those grades.

Q: Who typically uses it?

A: Manufacturers of parquet and wood flooring, timber processors and suppliers, inspectors and quality control staff, specifiers in procurement or construction, and standards bodies adopting the ISO text for national use.

Q: Is it current or superseded?

A: ISO 4561:2023 is current (published July 2023). It supersedes and replaces earlier ISO documents that addressed parquet raw elements, such as ISO 3398:1977, ISO 3399:1976 and ISO 5333:1978. National publications (BS ISO 4561:2023) mirror the ISO text.

Q: Is it part of a series?

A: It is a stand‑alone classification standard within the domain of timber/wood semi‑manufactures and is maintained under the work of ISO/TC 218 (timber). Related standards on timber products and testing may be referenced for complementary requirements.

Q: What are the key keywords?

A: Key keywords include wood, parquet, raw parquet elements, classification, grading, timber semi‑manufactures, oak, beech, birch, maple, fir, spruce, flooring, ISO 4561, BS ISO 4561.
