ISO 16000-11:2024

Overview

ISO 16000-11:2024 - "Indoor air - Part 11" specifies standardized procedures for sampling, transport, storage and preparation of test specimens used to determine emissions of volatile organic compounds (VOCs) from building products and furnishings. It covers three product classes: solid, liquid and combined products, and provides practical guidance to ensure representative, reproducible VOC emission measurements in emission test chambers or cells.

Key topics and technical requirements

• Scope & product classes: Procedures apply to solid (rigid/resilient), liquid (paints, varnishes, adhesives, etc.) and combined systems (e.g., coatings on substrates).
• Sampling timing and records: Samples should be taken as soon as possible after manufacture; dates and batch IDs must be recorded.
• Packaging and transport: Protect samples from contamination, heat, light and humidity. Typical packaging for solids: aluminium foil + polyethylene bag (or aluminised/ PVF-lined packaging). Liquid products: shipped in unopened cans/tubes. Aim to deliver samples to the lab within 14 days; longer transit times must be recorded.
• Storage before testing: Keep samples in original protective packaging at normal indoor conditions. Minimize storage time: testing should start within 8 weeks of sampling; wet-applied products in sealed containers should be tested within 4 months.
• Preparation of test specimens: Dimensions depend on chamber size and test scenario; specimen preparation methods are prescribed in informative annexes for solid, liquid and combined products. Examples:
  • Rolls: discard outer metre (or outer layer), sample from middle, and take specimen at least 50 cm from short-side edges.
  • Secure underside to an inert substrate (glass, stainless steel or aluminium foil) or place specimens back-to-back; seal edges with low-emitting aluminium tape or frames to isolate surface emissions.
  • Jointed products (tiles, laminates): assemble pieces to reflect the same proportion of joints as in use; do not use adhesive when assembling test specimen.
• Timing: Pack samples within 1 hour of sampling when applicable; record time between unpacking and specimen preparation.
• Cut-edge emissions: Specific preparation instructions for cut-edge testing are included.

Applications and users

ISO 16000-11:2024 is used by:

• Product manufacturers assessing VOC performance during R&D and quality control
• Independent testing laboratories preparing specimens for emission chamber/cell tests
• Indoor air quality consultants, specifiers and architects evaluating product suitability
• Regulators, certification bodies and green-building programs that reference VOC emission data The standard ensures consistent, reproducible specimen handling so emission results are comparable and meaningful for health, compliance and product development decisions.
