controlled within some range to ensure proper correlation of data obtained from measurements and tests conducted in various facilities Conduct measurement and test conditions under the following atmospheric conditions, unless otherwise specified In some cases, special ambient conditions may be needed and can be specified in the detail specification Table gives the standard range of atmospheric conditions for carrying out measurements and tests: Table ± Standard range of atmospheric conditions Condition Standard Temperature 23 °C ± °C Relative humidity 45 % ± 25 % Atmospheric pressure (limits are inclusive) Site ambient Keep variations in ambient temperature and humidity to a minimum during a series of measurements Calibration guidance The process of calibration may be defined as the set of operations which establish, under specified conditions, the relationship between values indicated by a measuring system and the known values of a reference material Once established, this relationship may be used to adjust the measuring system to correct for measurement bias Adjustment of the system may, for example, take the form of hardware or a software adjustment Follow the instructions given in the test procedure documents as may be necessary for calibration and adjustment of the apparatus to ensure successful application of the documents If suitable reference materials not exist, then consideration should be given to an appropriate strategy to minimise measurement uncertainty Record relevant information of the calibration process, such as the calibrated value and uncertainty of the reference material or test equipment used BS EN 60793-1-1:2008 – 10 – 60793-1-1 IEC:2008(E) Reference test methods Several attributes have an agreed-upon reference test method (RTM) This is the method that shall be used to settle disputes Categories of optical fibres The measurement methods and test procedures indicated in this standard apply to fibre categories described in Clause of IEC 60793-2, as appropriate Packaging For handling and shipping of optical fibres, the packaging device shall meet the following requirements: a) winding techniques shall enable the optical fibre to withstand transport and specified environmental conditions; b) the possibility of measuring the dimensions, transmission and optical characteristics of the optical
