The work of preparing International Standards is normally carried out through ISOtechnica
23、l committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with
24、the InternationalElectrotechnical 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 Internatio
25、nal Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational 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
26、subject of patentrights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 139 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 24, Conditioningatmospheres and physical tests for textile fabrics.This second edition cancels and replaces the fi
27、rst edition (ISO 139:1973), which has been technically revised,specifically by including the allowances for the uncertainty of the measurement in the overall tolerances fortemperature and relative humidity.BS EN ISO 139:2005+A1:2011EN ISO 139:2005+A1:2011 (E)vIntroductionThe tolerances for temperatu
28、re and relative humidity given in ISO 139:1973 were the tolerances for thetemperature and relative humidity measured in the laboratory, and without any consideration for the uncertaintyof measurement of the measuring devices being used.With the increased understanding since 1973 and the existence no
29、w of standards covering these issues (e.g.ISO 14253-1), it is now necessary to allow for the uncertainty of measurement when setting appropriatetolerances.This second edition of ISO 139 includes the allowance for uncertainty of measurement in the overall tolerancesfor temperature and relative humidi
30、ty.This means that although the tolerances for temperature and relative humidity appear more lenient than inISO 139:1973, in practice, the laboratory must still be controlled (measured temperature and humidity) toessentially the same level as stated in ISO 139:1973.BS EN ISO 139:2005+A1:2011EN ISO 1
