Full title and description

DIN EN 49-2:2015-10 — Wood preservatives — Determination of the protective effectiveness against Anobium punctatum (De Geer) by egg‑laying and larval survival — Part 2: Application by impregnation (laboratory method). This document specifies a laboratory procedure for testing impregnated wood to determine protective effectiveness or toxic values of wood‑preservative formulations against the furniture beetle Anobium punctatum.

Abstract

This European/DIN standard defines a test method in which wood specimens previously treated by full impregnation are exposed to Anobium punctatum adults; egg‑laying and subsequent larval survival are observed and recorded to assess protective effectiveness or toxic values of water‑soluble, water‑dispersible or water‑insoluble preservative formulations. The method may be used with ageing procedures (for example EN 73) where applicable.

General information

• Status: Published / Active as a DIN-adopted version of EN 49-2.
• Publication date: 01 October 2015 (edition identifier 2015-10).
• Publisher: Deutsches Institut für Normung (DIN), adopted from EN 49-2 (CEN).
• ICS / categories: 71.100.50 — Wood‑protecting chemicals.
• Edition / version: DIN EN 49-2:2015-10 (English/German texts available).
• Number of pages: 24 (typical DIN publication length; some catalog listings indicate small variations by publisher format).

Scope

The standard covers a laboratory test for determining the preventive effect or toxic values of wood preservatives against infestation by Anobium punctatum when preservatives are applied by full impregnation. It is applicable to water‑insoluble chemicals, organic formulations (as supplied or diluted), water‑dispersible organic formulations and water‑soluble materials such as salts. The procedure can be combined with ageing procedures (for example EN 73) to evaluate durability over time.

Key topics and requirements

• Preparation of test specimens and impregnation (full‑penetration) application of the preservative.
• Controlled exposure of specimens to adult Anobium punctatum and monitoring of egg‑laying behaviour.
• Observation and recording of larval survival and development as the primary effectiveness endpoint.
• Test conditions and environmental controls (temperature, humidity, conditioning and holding periods) to ensure reproducible results.
• Data reporting requirements, calculation of toxic values / protective effectiveness and interpretation guidance; possibility to combine with ageing procedures (EN 73) for long‑term assessment.

Typical use and users

Used by wood‑preservative manufacturers, independent testing laboratories, university and research institutes working on wood protection, product development teams, and regulatory bodies evaluating insecticidal performance and registration dossiers for wood‑preservative products. Laboratories refer to this standard when producing comparative efficacy data and when validating formulations or treatment processes intended to protect timber against Anobium punctatum.

Related standards

EN 49-1 / EN 49‑1:2016 — Part 1: Application by surface treatment (laboratory method) — covers comparable tests for surface‑applied preservatives. EN 73 (ageing procedures) is referenced for conditioned/aged assessments that complement the EN 49 series. Earlier editions of EN 49-2 (for example 2005) were superseded by the 2015 edition.

FAQ

Q: What is this standard?

A: DIN EN 49-2:2015-10 is the DIN-adopted version of the European standard that defines a laboratory test for assessing the protective effectiveness of wood preservatives against Anobium punctatum when applied by full impregnation.

Q: What does it cover?

A: It specifies specimen preparation, impregnation application, exposure to adult beetles, observation of egg‑laying and larval survival, test conditions and reporting methods to determine protective performance or toxic values. The method applies to a wide range of preservative formulations (water‑soluble, water‑dispersible or insoluble).

Q: Who typically uses it?

A: Manufacturers, contract and independent test laboratories, researchers, product developers and regulators concerned with timber protection and insecticidal efficacy testing.

Q: Is it current or superseded?

A: The 2015 edition (DIN EN 49-2:2015-10) is the published edition replacing earlier versions (for example the 2005 edition). Listings show it as the active/adopted EN/DIN version; users should check national catalogues or DIN for any subsequent revisions or withdrawal notices (status can change if a revision project is started).

Q: Is it part of a series?

A: Yes — it is Part 2 of the EN 49 series (Part 1 covers surface application). The series addresses egg‑laying and larval survival test methods for different application techniques of wood preservatives.

Q: What are the key keywords?

A: Wood preservatives; Anobium punctatum; impregnation; laboratory efficacy test; egg‑laying; larval survival; EN 49-2; DIN.
