ISO 17299-2:2014

Overview

ISO 17299-2:2014 - "Textiles - Determination of deodorant property - Part 2: Detector tube method" specifies a standardized laboratory method for measuring the deodorant (odour‑reducing) performance of textile products using detector tubes. The method targets specific odour component chemicals: ammonia, acetic acid, methyl mercaptan, and hydrogen sulfide. It provides a repeatable procedure to quantify the odour reduction rate (ORR) of textile specimens, enabling consistent evaluation of deodorant treatments and functional fabrics.

Key topics and technical requirements

• Scope & principle: Measures concentration of each odour chemical before and after exposure to a textile specimen; ORR (%) = (B − A) / B × 100, where B = average concentration without specimen, A = average concentration with specimen.
• Target chemicals: Ammonia, acetic acid, methyl mercaptan, hydrogen sulfide - each tested individually.
• Detector tube ranges (accuracy ±5%):
  • Ammonia: 0.2–200 μl/l
  • Acetic acid: 0.25–50 μl/l
  • Methyl mercaptan: 0.5–10 μl/l
  • Hydrogen sulfide: 0.2–6 μl/l
• Reagents & gases: Describes preparation of testing gases including ammonia solution, acetic acid reagent, and standard diluted gases for methyl mercaptan and hydrogen sulfide; use of high‑purity diluent gas.
• Apparatus & consumables: Detector tubes, plastic bags (1 L, 5 L, 50 L), air pump (0.2–5 L/min) or integrating flow meter, syringes, airtight stoppers.
• Test conditions: Conditioning per ISO 139 (20 °C, 65% RH); specimen sizes and mass specifications; three replicate specimens per test.
• Procedure highlights: Prepare master gas, insert 3 L test gas into 5 L bags, contact specimens for 2 hours, extract 100 ml sample and read detector tube discoloration to obtain concentration values.
• Quality info: Annexes include round‑robin (interlaboratory) results and detector tube supplier information to support method reproducibility and implementation.

Applications and users

ISO 17299-2 is practical for:

• Textile R&D teams developing deodorant finishes or functional apparel (sportswear, workwear).
• Quality control and performance testing labs validating product claims for odour control.
• Manufacturers verifying batch consistency of treated fabrics.
• Certification bodies and procurement teams requiring objective deodorant performance data. The detector tube method is notably simple and cost‑effective, suitable when commercial detector tubes for target chemicals are available.
