Page 3EN 13549:2001ForewordThis European Standard has been prepared by Technical Committee CEN/TC 328 " Standardmeasuring system for cleaning performance", the secretariat of which is held by NEN.This European Standard shall be given the status of a national standard, either by publication of anidentical text or by endorsement, at the latest by November 2001, and conflicting national standardsshall be withdrawn at the latest by November 2001.According to the CEN/CENELEC Internal Regulations, the national standards organizations of thefollowing countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands,Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.The annexes A, B and C are informative.IntroductionWith the help of a good control system cleaning services can be inspected for quality. This immediatelycreates questions of what should be inspected, how inspections should be carried out, and whatmeasurement criteria should be used.There has been, until now, no comprehensive view taken of the measuring devices and systemsavailable that can be used easily in the work place for inspecting cleaning service activities andproviding an objective view of the results achieved.That is the purpose of this framework model for quality measuring systems. It provides a template ofacknowledged best practice within which locally or nationally acceptable systems can continue to beused and developed.This is the best way to proceed as the work of the Technical Committee has established the existenceof a wide range of quality control systems for cleaning with a variety of features. These have beendeveloped in response to specific needs or to fit local regulations and laws; in some cases they have along history of successful use. With the help of this standardized framework model, all systems can behelped towards greater objectivity and completeness.SIST EN 13549:2002

Terms and definitionsFor the purposes of this standard, the following terms and definitions apply:3.1quality measuring systeminspection system designed to assess whether the services defined and agreed between two partiesmeet the quality level that is intended to be present according to the requirements expressed explicitlyor implicitly in that agreementNOTE
In this standard hereafter the quality measuring system is referred to as “the system”.3.2cleaning performanceresult of cleaning services and cleaning related services according to requirementsNOTE
Cleaning services are cleaning activities of a cleaning operative.3.3specificationdocument stating the requirements with which the service has to conformNOTE
The specification is the part of a contract or service level agreement, that will define theitems covered by the system (see ISO 8402:1994, 3.14).SIST EN 13549:2002

A sample of these clusters is taken at random and all sampling units which constitutethem are included in the sample.EXAMPLE
When selecting items for inspection a number of areas may be chosen. It is called clustersampling when all the items within these areas are inspected3.21stratified samplingin a population which can be divided into different mutually exclusive and exhaustive subpopulations(called strata), sampling carried out in such a way that specified proportions of the sample are drawnfrom
