Описание (английский):

ISO 139:2005 defines the characteristics and use of a standard atmosphere for conditioning, for determining the physical and mechanical properties of textiles and a standard alternative atmosphere that may be used if agreed between parties.

Abstract

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

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.
