Overview - EN ISO 139:2005 (Textiles - Standard atmospheres for conditioning and testing)

EN ISO 139:2005 (ISO 139:2005) is the CEN-endorsed international standard that defines standard atmospheres for conditioning textiles and for determining their physical and mechanical properties. The document specifies both a primary standard atmosphere and a standard alternative atmosphere (usable only by agreement), describes tolerance zones, monitoring and control requirements, and reporting elements for laboratory testing of textile materials.

Key topics and technical requirements

• Standard atmospheres
  • Primary: 20.0 °C and 65.0 % relative humidity (RH).
  • Alternative (by agreement): 23.0 °C and 50.0 % RH.
• Tolerances
  • Temperature: ±2.0 °C
  • Relative humidity: ±4.0 %
  • Tolerances account for measurement uncertainty (see Annex B and introduction).
• Measuring device requirements
  • Resolution: 0.1 °C (temperature), 0.1 % RH (humidity) or better.
  • Uncertainty: ±0.5 °C (temperature), ±2.0 % RH (humidity) or better.
  • Calibration and regular determination of measurement uncertainty are required.
• Control and monitoring
  • Continuous monitoring with suitable sensors/recorders; sampling frequency must detect short-term out-of-tolerance events (Annex A).
  • Spatial checks throughout the conditioned space (minimum density specified in Annex A).
  • Monitoring devices must be separate from HVAC control sensors.
• Conditioning procedures
  • Pre-conditioning, if used, should bring specimens near equilibrium in low-humidity conditions (RH 10–25 %, temperature not exceeding 50.0 °C).
  • Equilibrium criterion: successive weighings at 2-hour intervals showing no progressive mass change > 0.25 %.
• Test report essentials
  • Specimen identification, reference to ISO 139:2005, details of conditioning atmosphere, and any deviations.

Practical applications and users

EN ISO 139:2005 is used to ensure repeatable, comparable textile test results across:

• Textile testing laboratories and accreditation bodies
• Manufacturers and suppliers specifying test conditions for quality control
• Research and development teams studying material properties
• Procurement and certification entities that require standardized conditioning before property evaluation

Adoption of the standard improves comparability of tensile tests, dimensional stability measurements, moisture-related behavior and other textile performance tests by ensuring consistent temperature and humidity control.

Related standards

• ISO 14253-1 - decision rules and measurement uncertainty considerations (referenced for tolerance/conformity concepts)
• ISO 3534-2 - applied statistics vocabulary
• International vocabulary of metrology (VIM)

ISO 139:2005(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO139 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC24, Conditioning
atmospheres and physical tests for textile fabrics.
This second edition cancels and replaces the first edition (ISO 139:1973), which has been technically revised,
specifically by including the allowances for the uncertainty of the measurement in the overall tolerances for
temperature and relative humidity.
