26、atory, and without any consideration for the uncertainty of measurement of the measuring devices being used. With the increased understanding since 1973 and the existence now of standards covering these issues (e.g. ISO 14253-1), it is now necessary to allow for the uncertainty of measurement when s

27、etting appropriate tolerances. This second edition of ISO 139 includes the allowance for uncertainty of measurement in the overall tolerances for temperature and relative humidity. This means that although the tolerances for temperature and relative humidity appear more lenient than in ISO 139:1973,

28、 in practice, the laboratory must still be controlled (measured temperature and humidity) to essentially the same level as stated in ISO 139:1973. DIN EN ISO 139:2011-10 EN ISO 139:2005 + A1:2011 (E) 5 1 Scope This International Standard defines the characteristics and use of a standard atmosphere f

29、or conditioning, for determining the physical and mechanical properties of textiles and a standard alternative atmosphere that may be used if agreed between parties. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 standard atmosphere environm

30、ent of controlled relative humidity and temperature in which textiles are conditioned and tested 2.2 relative humidity ratio, expressed as a percentage, of the actual pressure of the water vapour in the atmosphere to the saturation vapour pressure at the same temperature and at the same pressure 2.3

34、 the atmosphere in a static state“ DIN EN ISO 139:2011-10 EN ISO 139:2005 + A1:2011 (E) 6 3 !Requirements 3.1 Standard atmosphere The standard atmosphere shall have a temperature of 20,0 C and a relative humidity of 65,0 %. 3.2 Alternative standard atmospheres The alternative, but not equivalent, at

35、mosphere (3.2.1 or 3.2.2) may only be used if the parties involved agree on its use, and the alternative atmosphere used shall be reported. 3.2.1 Specific standard atmosphere The specific standard atmosphere shall have a temperature of 23,0 C and a relative humidity of 50,0 %. 3.2.2 Tropical standar

36、d atmosphere The tropical standard atmosphere shall have a temperature of 27,0 C and a relative humidity of 65,0 %. 3.3 Tolerance zone for the standard atmosphere and the alternative standard atmospheres The tolerance for temperature is 2,0 C. The tolerance for relative humidity is 4,0 %. NOTE For a

37、 control of standard atmospheres, see Annex A.“ 4 Apparatus 4.1 Measuring devices for temperature and relative humidity Measuring devices should meet the following requirements: resolution: for temperature, 0,1 C or better, and for relative humidity, 0,1 % or better; uncertainty of measurement: for

38、temperature, 0,5 C or better, and for relative humidity, 2,0 % or better. Calibration to determine the uncertainties of the measurement sensors shall be carried out regularly. 4.2 Limitations to measurement devices Devices used for the measurement of relative humidity and temperature in the conditio

39、ned atmosphere shall be separate from those normally used for controlling heating, ventilation and air conditioning ducts. 5 Procedures 5.1 Reading frequency for continuous monitoring Sensor readings of a conditioned atmospheric enclosure shall be made at such a frequency that any short-term out-of-

40、tolerance-limit events can be detected (see Annex A for additional information). 5.2 Spatial variation More than one measuring devices might be required to ensure adequate monitoring of the atmospheric conditions throughout the enclosure (see Annex A). DIN EN ISO 139:2011-10 EN ISO 139:2005 + A1:201

41、1 (E) 7 5.3 Pre-conditioning Before conditioning a textile, pre-conditioning might be required. If so, the textile shall be brought approximately to equilibrium in an atmosphere having a relative humidity of between 10,0 % and 25,0 % and a temperature not exceeding 50,0 C. 5.4 Conditioning Before a

42、textile is tested, it shall be conditioned by placing it in the atmosphere for testing in such a way that the air flows freely through the textile, and keeping it there for the time required to bring it into equilibrium with the atmosphere. !Unless otherwise specified, the textile should be consider

43、ed to be in equilibrium when successive weighings show no progressive change in mass greater than 0,25 %. In the case of the standard atmosphere in a conditioned laboratory, successive weighing should be done on the textile at intervals of 2 h. However, where accelerated conditioning systems are use

44、d, a shorter interval of 2 min to 10 min should be used.“ 6 Test report If required, laboratory test reports shall include the following: a) identification of the test specimen; b) reference to this International Standard (ISO 139:2005); c) details of the atmosphere used for conditioning and testing

45、; d) details of any deviation from this International Standard. DIN EN ISO 139:2011-10 EN ISO 139:2005 + A1:2011 (E) 8 Annex A (normative) Control of standard atmosphere A.1 General An air-conditioned laboratory shall provide and maintain a standard atmosphere as defined in 3.1 or 3.2, within the to

46、lerance zone as defined in 3.3. The specified condition of temperature and relative humidity shall be considered to have been attained when the following requirements are satisfied. a) The mean temperature and relative humidity over any continuous 1 h period shall conform to the tolerance zone at th

47、e standard atmosphere conditions. b) The spatial variation of the standard atmosphere shall comply with the specified tolerance zone. A.2 Apparatus Apparatus shall be in accordance with the requirements of 4.1. A device such as a digital or electronic sensor with a recorder output for continuous mon

48、itoring is suitable. A.3 Procedure A.3.1 Spatial variation Monitor periodically the spatial variation of the atmospheric conditions within the laboratory at various positions. The number of position checks required shall be equivalent to a minimum of 1 per 50 m3. Where the spatial variation does not

49、 comply with the tolerances, the air movement within the laboratory shall be checked. A.3.2 Positioning of the continuous monitoring devices Variations in temperature and relative humidity are likely to exist throughout the working space. The selection of an appropriate monitoring position can be made only after position checks have been conducted. The selected position should be close to the main working area.
