Full title and description

ISO 12460-5:2015 — Wood‑based panels — Determination of formaldehyde release — Part 5: Extraction method (called the perforator method). This standard specifies the perforator extraction procedure for determining formaldehyde content of unlaminated and uncoated wood‑based panels and is intended primarily for factory production control and laboratory determination of formaldehyde content.

Abstract

ISO 12460-5:2015 defines an extraction method (the perforator method) in which formaldehyde is extracted from test pieces by boiling toluene, transferred into distilled or demineralized water and determined (typically by the acetylacetone photometric method, with an optional fluorimetric determination) to quantify formaldehyde content for uncoated, unlaminated wood‑based panels.

Scope

This part of ISO 12460 specifies the perforator extraction method for the determination of formaldehyde content of unlaminated and uncoated wood‑based panels (e.g., particleboard, MDF, OSB, plywood when uncoated). The procedure covers sample preparation, extraction by boiling toluene, transfer of extracted formaldehyde to water, analytical determination (acetylacetone photometric method as the primary procedure with an optional fluorimetric technique), and requirements for conditioning, calibration and quality assurance. The method is intended for factory production control and for laboratories assessing formaldehyde content of panels, including provisions and modifications to improve detection limits and reproducibility for low‑emitting boards.

Key topics and requirements

• Definition and purpose of the perforator extraction method for formaldehyde determination.
• Sample dimensions, number of test pieces, and improved weighing accuracy for low‑emitting boards.
• Extraction steps: perforator apparatus use, boiling with toluene, and sequential extractions (including modified third extraction procedure).
• Transfer of extracted formaldehyde into distilled/demineralized water and analytical determination by the acetylacetone (photometric) method; fluorimetric determination provided as an option.
• Conditioning climate requirements (example: relative humidity around 50 % ± 5 % for conditioning) and specified water bath temperature (raised to about 60 °C in the revision to improve sensitivity).
• Calibration procedures, quality assurance/quality control (including blank tests and calibration curves), and inclusion of modification factors for moisture content.
• Precision, detection limits and recommendations for increased sample mass or altered cell length for very low emitting materials.

Typical use and users

Typical users include manufacturers of wood‑based panels (for factory production control), independent testing laboratories, certification and conformity assessment bodies, regulatory agencies, product specifiers, architects and sustainability assessors who need formaldehyde content data for compliance, labeling or indoor‑air quality evaluations, and researchers studying emissions from wood products.

Related standards

ISO 12460 is a multi‑part series covering different test methods for formaldehyde release. Closely related parts include ISO 12460‑1 (1 m³ chamber method), ISO 12460‑2 (small‑scale chamber method), ISO 12460‑3 (gas analysis method) and ISO 12460‑4 (desiccator method). National and regional variants (for example BS EN ISO versions) and predecessor standards such as EN 120 are also related and have been harmonized with ISO revisions.

FAQ

Q: What is this standard?

A: ISO 12460‑5:2015 is the second‑edition international standard that specifies the perforator extraction method for determining formaldehyde content in unlaminated and uncoated wood‑based panels.

Q: What does it cover?

A: It covers sample preparation, the perforator extraction procedure (boiling with toluene and transfer to water), analytical determination (acetylacetone photometric method with an optional fluorimetric method), calibration and quality assurance, and procedural details to improve detection and reproducibility—particularly for low‑emitting boards.

Q: Who typically uses it?

A: Manufacturers for factory production control, testing and calibration laboratories, certification bodies, regulators and product specifiers concerned with formaldehyde content and emissions from wood‑based panels.

Q: Is it current or superseded?

A: ISO 12460‑5:2015 is the current published edition (Edition 2, published November 2015). The earlier 2011 edition was withdrawn when the 2015 edition was issued; the 2015 edition was reviewed and confirmed in a subsequent ISO review cycle.

Q: Is it part of a series?

A: Yes — it is Part 5 of the ISO 12460 series (Wood‑based panels — Determination of formaldehyde release). Other parts address chamber methods, gas analysis and desiccator/desiccator‑type procedures and together provide a suite of methods for different testing needs.

Q: What are the key keywords?

A: Perforator method; extraction method; formaldehyde content; wood‑based panels; acetylacetone; fluorimetric determination; factory production control; emission testing.
