Full title and description

ISO 14184-2:2011 — Textiles — Determination of formaldehyde — Part 2: Released formaldehyde (vapour absorption method). This international standard specifies a vapour‑absorption procedure for determining the amount of formaldehyde released from textile materials under accelerated storage conditions.

Abstract

ISO 14184-2:2011 defines a laboratory method to measure releasable (released) formaldehyde from textiles in any form using a vapour absorption technique. The procedure is intended for results in the range 20 mg/kg to 3 500 mg/kg (values below 20 mg/kg are reported as “not detectable”). The standard is complementary to ISO 14184-1:2011, which covers free and hydrolysed formaldehyde (water extraction method).

Scope

Specifies a vapour‑absorption test to quantify formaldehyde released from textile articles after accelerated storage. The method applies to textiles in any form and is intended for measuring releasable formaldehyde in the working range 20 mg/kg to 3 500 mg/kg; results below 20 mg/kg are reported as not detectable. It does not replace ISO 14184-1:2011, which covers free and hydrolysed formaldehyde determined by water extraction.

Key topics and requirements

• Test principle: generation of formaldehyde vapour from a conditioned sample followed by absorption and quantitative determination.
• Applicable range: 20 mg/kg (lower reporting limit) to 3 500 mg/kg.
• Sample conditioning and accelerated storage details to simulate releasable formaldehyde emissions.
• Analytical end‑point and calculation procedures for reporting releasable formaldehyde (expressed in mg/kg of textile).
• Notes on limits of detection and statements for “not detectable” results below the lower limit.

These technical requirements and ranges are defined in the ISO text describing the vapour absorption technique and result interpretation.

Typical use and users

Used by textile testing laboratories, quality assurance teams in textile and apparel manufacturers, compliance and regulatory bodies, independent test houses, and R&D organisations assessing fabric safety, emissions, and conformity with buyer or regulatory limits for formaldehyde. It is employed when releasable (off‑gassing) formaldehyde needs measurement rather than only extractable/free formaldehyde.

Related standards

Directly related to ISO 14184-1:2011 (Part 1 — Free and hydrolysed formaldehyde, water extraction method). Various regional/adopted versions exist (for example EN/EN ISO adoptions in several countries) that reproduce ISO 14184-2:2011 as a national/regional standard. The 2011 edition superseded ISO 14184-2:1998.

FAQ

Q: What is this standard?

A: ISO 14184-2:2011 is the ISO standard that specifies a vapour‑absorption laboratory method to determine the amount of formaldehyde released from textiles under accelerated storage conditions.

Q: What does it cover?

A: It covers the test principle, sample conditioning, the vapour absorption procedure, analytical determination and calculation/reporting rules for releasable formaldehyde in textiles between 20 mg/kg and 3 500 mg/kg; values below 20 mg/kg are reported as "not detectable".

Q: Who typically uses it?

A: Accredited and commercial textile testing laboratories, manufacturers and their QA teams, compliance/regulatory organisations and laboratories performing product safety or emissions testing for textiles and related articles.

Q: Is it current or superseded?

A: The 2011 (Edition 2) text replaced the 1998 edition. ISO’s record shows the 2011 edition was reviewed and confirmed (most recently at its five‑year review), so the 2011 edition remains the current published edition unless ISO has issued a later revision after that confirmation. Users should check ISO or their national body for any more recent revisions or confirmations beyond the 2011 text.

Q: Is it part of a series?

A: Yes — it is Part 2 of ISO 14184. Part 1 (ISO 14184-1:2011) covers free and hydrolysed formaldehyde by water extraction; Part 2 addresses released formaldehyde by vapour absorption.

Q: What are the key keywords?

A: Keywords include formaldehyde, released formaldehyde, vapour absorption, textiles testing, releasable emissions, ISO 14184-2.
