Full title and description

ISO 10283:2007 — Binders for paints and varnishes — Determination of monomeric diisocyanates in isocyanate resins. Specifies a gas‑chromatographic method for the qualitative and quantitative determination of residual monomeric diisocyanates (for example TDI, HDI, IPDI, MDI and similar compounds) in isocyanate/polyisocyanate resins and solutions of such resins used in the formulation of paints, varnishes and related coating materials.

Abstract

ISO 10283:2007 defines a standardized analytical procedure using gas chromatography (GC) to measure monomeric diisocyanates present in isocyanate resins. The method covers sample preparation, reagents, GC operating conditions (including column conditioning and detector selection), calibration with an internal standard and the expression of results so that laboratories and manufacturers can obtain reproducible, comparable measurements for quality control and regulatory use.

Scope

The standard applies to the determination of monomeric diisocyanates in isocyanate (polyisocyanate) resins and in solutions prepared from these resins when they are used in the formulation of paints, varnishes and similar coating materials. It is intended to quantify the low levels of volatile monomer typically found in commercial resins to support product quality control, specification compliance and safety/regulatory assessments.

Key topics and requirements

• Analytical principle: gas chromatography (GC) separation of individual diisocyanates followed by detection (commonly flame ionization detector, FID) and quantification against an internal standard.
• Target analytes: typical monomeric diisocyanates such as toluene diisocyanate (TDI), hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPDI) and diphenylmethane diisocyanate (MDI), plus other relevant diisocyanates.
• Reagents and calibration: instructions for solvent selection, preparation and storage of reference standards and internal‑standard solutions; emphasis on moisture‑free handling to avoid isocyanate reaction.
• Apparatus and column conditioning: recommended GC column types and conditioning procedures to ensure reproducible retention and peak shape for low‑volatility analytes.
• Sampling and sample preparation: guidance for representative sampling of resins and preparation of solutions for injection to minimise loss or transformation of monomeric isocyanates.
• Method performance and expression of results: calibration, calculation of concentrations (mass fraction or mg/kg), detection/quantification considerations and reporting conventions for quality control and regulatory records.

Typical use and users

ISO 10283:2007 is used by analytical and quality‑control laboratories in the coatings and specialty chemicals industries, resin manufacturers, paint formulators, third‑party testing laboratories and regulatory bodies. Typical uses include incoming raw‑material checks, batch release testing, conformity assessment against specification limits, troubleshooting of production and supporting safety and regulatory documentation.

Related standards

Relevant related documents include the earlier edition ISO 10283:1997 (withdrawn and replaced by the 2007 edition) and regional/adopted versions such as EN ISO 10283:2007 and national equivalents that adopt the ISO method. Other standards and guidance on isocyanate handling, workplace monitoring and related analytical methods may also be consulted alongside ISO 10283 for comprehensive quality and safety programs.

FAQ

Q: What is this standard?

A: ISO 10283:2007 is an international standard that specifies a gas‑chromatographic method for determining monomeric diisocyanates in isocyanate resins and their solutions used in paints and related coating materials.

Q: What does it cover?

A: It covers the analytical principle (GC), required reagents and reference solutions, apparatus and column conditioning, sample preparation and sampling, analytical procedure and how to express and report results for monomeric diisocyanates such as TDI, HDI, IPDI and MDI.

Q: Who typically uses it?

A: Analytical and QC laboratories, resin and paint manufacturers, contract testing labs and regulatory or conformity assessment bodies that need reproducible measurements of residual monomeric diisocyanates in coating binders.

Q: Is it current or superseded?

A: The 2007 second edition is the current published edition and supersedes the 1997 edition. Users should check with their national body or ISO for any later revisions or confirmations, but the 2007 edition remains the recognized technical document for this method.

Q: Is it part of a series?
