(Main)Wood preservatives - General guidance on sampling and preparation for analysis of wood preservatives and treated timber
General Information
- Abstract
This European Standard gives guidance on the general procedures to be followed in the sampling and preparation for analysis of wood preservatives and preservative-treated timber.
This European Standard is applicable to the provision of appropriate samples for analysis which can be used to check the content of active and other ingredients in preservative formulations, and the content of active and other ingredients of wood preservatives in treated timber, either before, during or after the service life of the timber.
NOTE 1 Methods of sampling creosote and creosote-treated timber are described in EN 1014-1, 1014-2 and EN 12490. These are to be used in preference to the recommendations in this European Standard.
NOTE 2 No attempt has been made in this document to lay down detailed procedures to be adopted for control purposes at manufacturing plants where large volumes of preservatives are to be sampled. Nor does it attempt to establish procedures for checking the compliance of batches of treated timber with specifications demanding a defined level of treatment (see 6.2).

EN 212:2003 - Wood preservatives: sampling & preparation (CEN)
Overview
EN 212:2003, published by CEN, provides general guidance on the sampling and sample preparation required for the analysis of wood preservatives and preservative-treated timber. It covers how to obtain representative samples for checking the content of active and other ingredients in preservative formulations and in treated timber - before, during or after the service life of the timber. The standard is advisory: it sets general procedures and safety precautions rather than detailed factory control protocols.
Key topics and technical requirements
- Scope and purpose: Guidance for producing representative samples suitable for chemical analysis of preservatives and treated timber.
- Sampling strategy: Recommendations on selection of containers to sample (minimum number ≈ nearest whole number to the square root of half the total containers in a consignment).
- Sample containers & inert materials: Use container materials inert to the preservative (e.g., glass for many solvents; polyethylene for some boron/fluorine preservatives). Avoid polyethylene with hydrocarbon solvents.
- Solid, paste and liquid sampling:
- Solid preservatives: use a sampling spear (internal diameter ≈ 30 mm), take five spear samples per drum and combine; reduce by coning and quartering to a ~200 g test sample; sieve if required (nominal 2.00 mm).
- Paste preservatives: homogenize, take multiple depths (surface, middle, near base) with a wide‑mouthed can, combine and mix.
- Liquid sampling: (guidance provided in the standard - follow inert container and representative withdrawal principles).
- Treated timber sampling: General procedures for selecting and taking wood samples; methods for moisture content determination of treated timber and guidance on thin-section coring (specific borers for thin sections).
- Safety: Treat all preservatives as potentially toxic; use PPE when handling wet or solvent-containing timber; use dust extraction and respiratory protection when machining treated timber; observe flammable-liquid regulations.
- Documentation: Include a sampling report specifying lot/consignment, sampling plan, storage conditions and any irregularities.
Applications and users
- Quality control and R&D laboratories analyzing preservative formulations and retained active ingredient levels.
- Timber treatment plants and manufacturers preparing samples for external testing.
- Certification bodies, inspectors and forensic labs performing arbitration or compliance checks.
- Researchers studying preservative distribution, penetration and long-term performance of treated timber.
Related standards

- EN 1014-1, EN 1014-2 and EN 12490 - Specific sampling rules for creosote and creosote-treated timber (use in preference to EN 212 where applicable)
- ISO 6206 - Sampling vocabulary and concepts
EN 212:2003 is a practical reference for ensuring representative, safely handled samples for accurate chemical analysis of wood preservatives and treated timber.
