201 – 87 – Annex L (informative) Uncertainty of measurements in the present document L.1 Why is uncertainty important? When a m easurement has been perform ed giving a figure as a result for som e quantity (also known as the measurand) we m ay ask how sure can we be about this figure I n other words: – I f we repeat the measurem ent will we then get the sam e result? – I f another group or another laboratory perform s the m easurem ent how close will we expect the results to be? By means of an uncertainty budget we m ay calculate an uncertainty interval y ± U, where y is the m easurement result and U the expanded uncertainty that is estim ated to give the interval a high probability (often 95 %) to cover the true value, Y, of the m easurand U is said to be the uncertainty associated with the result y The uncertainty interval of a m easurem ent is therefore a basis for qualifying the measurem ent The more narrow we want the confidence interval i e the sm aller we want the value of the uncertainty U, the more careful we often have to be about the measurem en t method, the measuring equipm ent, the training of the operators and the num ber of repetitions of the sam e experiment L.2 Documents referenced in this annex The following documents are included in the Bibliograph y of this PAS and should be consulted when examining the issue of uncertainty of m easurement in an y detail: – I SO/I EC Guide to the Expression of U ncertainty in Measurem ent (also known as “GUM”); – I SO 5725 (all parts); – I EC/TR 61 923 L.3 L.3.1 Ways to access uncertainty General There are in principle two ways to estim ate uncertainty: a bottom up m ethod and a top down method I t is generall y recom m ended that the two m ethods be used in parallel to achieve a reliable estim ate of the uncertainty budget L.3.2 The bottom up method This m ethod is set out in the I SO/I EC Guide to the Expression of Uncertainty in Measurement I n this m ethod the test result y is expressed as a function of input quantities This function is often the formula used for the calculation of the result I n our case the y m ay be one of the final test results like water consumption, energy consum ption, washing performance, spin speed , spin drying perform ance, program duration or rinsing efficiency The input quantities may be tem perature, m asses, tim es, power, etc The magnitude of all the uncertainty contributions of each input quantity is estim ated The maxim um perm itted uncertainty is normall y defined in the standard H owever, the actual uncertainty of m easurem ent for the equipment used during the test should be used – 88 – I EC PAS 631 25:201 © I EC 201 By com bining the uncertainties of the input quantities according to the law of propagation of uncertainty (see the I SO/I EC Guide to the Expression of Uncertainty in M easurement for details), the uncertainty of the result y can be calculated With this calculation it can be seen how a specific uncertainty contribution from an input quantity influences the combined uncertainty of the final result and therefore how a reduction in an uncertainty contribution from an input quantity will influence the combined uncertainty of the final result Uncertainties may usuall y be reduced through a number of strategies including m aking more m easurements, using other methods or other equipm ent, but these usuall y have an additional cost associated with them We can use this information to put our effort into those aspects that reduce the uncertainty of the final result in the most cost effective way L.3 Th e top d own m eth od This method is set out in I EC/TR 61 923 In this m ethod the reproducibility standard deviation is estim ated from testing of the same machine (or the same model) in different laboratories using the same standard m ethod This type of testing is norm all y called a “ring-test” or “round-robin test” The reproducibility standard deviation of the test results can then be seen as the inherent uncertainty of the measurem ent m ethod as it m ay be influenced by rem aining differences in the am bient, the people and whatever else m ay be different between different m easurem ents at different laboratories I n principle it is onl y valid for the m achine investigated in this ring-test, but results m ay also be extended to similar types of m achines I t is im portant to note that this type of estimate also includes the inherent variability of the test wash i n g m ach in e , which can be particularl y problem atic if there are sophisticated electronic controls or fuzzy logic programmes in operating during tests Factors such as overloading can also increase the variability (and increase uncertainty) of the results Where different machines are tested for comparison in different laboratories, there will also be some differences arising from production variability, so great care needs to be exercized Therefore the two m ethods “bottom up” and “top down” may be used in parallel to achieve a reliable estimate of the uncertainty budget But both m ethods depend on the validity of the model or the data used L U ncertai nty of measu rement i n the present document Reviewing actual round-robin test results, where m achines are tested in different laboratories, will allow an estimate of the relative expanded uncertainties to be made This data illustrates the best achievable result in using this standard in selected laboratories M easu red property Rel ati ve expan d ed u n certai n ty of m easu red val u e (k = ) Washing perform ance Energy consum ption Water consum ption Final m oisture Prog ram m e tim e val ues can be reported in a Technical report after actual tests invol vin g different laboratories Wool shrinkage The values in the Technical Report define the level of uncertainty of the m easurem ent when the sam e m achine is tested in a number of laboratories which follow this standard They are I EC PAS 631 25:201 © I EC 201 – 89 – onl y valid for those type of m achines assessed in the Technical Report; other machine types may behave differentl y, also affecting these uncertainty values I t is critical that laboratories m eet the requirements of the relevant standard whenever results are reported Additional details may need to be reported during round robin tests Laboratories are encouraged to check their alignment with other laboratories through participation in inter-laboratory testing whenever possible L.5 Reporting un certai nty I n sum mary, the uncertainty of m easured results has two sources: ) The statistical uncertainty of what is m easured as expressed in the sample standard deviation as calculated below, showing the accuracy of the measurem ent in the laboratory having done the measurem ent (noting that this m easurem ent also includes m achine variability) The calculation of standard deviation for a number of param eters is set out in Clause 2) The uncertainty of the m easuring method itself This is expressed as expanded uncertainty, where it is comm on to set the borders at a 95 % confidence interval, which gives the minimum and maxim um value within which the average measured result undertaken at an y other laboratory following this standard could be expected to fall Standard deviation of any parameter is set out as follows: s= n ∑ i =1 (x − xi ) ² n −1 i where: th term of parameter x xi is the xi is the m ean of all n terms of param eter x n is the num ber of m easurem ents of param eter x i Reporting of test results needs to have all of this information to allow a full j udgement of the m easured result: average measured value, standard deviation (across all test ru n s ) and expanded uncertainty As an exam ple, where the expanded uncertainty on energy consumption was found to be %, the data should be reported in the following form: Average energy measured Standard deviation of m easurem ent: Expanded uncertainty: Reporting: Energ y consumption: Average m easured: Standard deviation: Expanded uncertainty: , 44 kWh 0, 05 kWh % of ,44 kWh = 0, kWh , 44 kWh ± 0,05 kWh ± 0, kWh I nterpretation: Testing the same m achine in another laboratory following this standard, the expected average value (at 95 % confidence) should lie between , 30 kWh and , 58 kWh – 90 – I EC PAS 631 25:201 © I EC 201 Annex M (normative) Test report – Data to be reported M.1 General This annex presents the data to be reported for the reference
