18、d by NEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2001, and conflicting national standards shall be withdrawn at the latest by November 2001. According to the CENKENELEC Internal
19、Regulations, the national standards organizations of the following 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
20、the United Kingdom. The annexes A, B and C are informative. Introduction 0 With the help of a good control system cleaning services can be inspected for quality. This immediately creates questions of what should be inspected, how inspections should be carried out, and what measurement criteria shoul
21、d be used. There has been, until now, no comprehensive view taken of the measuring devices and systems available that can be used easily in the work place for inspecting cleaning service activities and providing an objective view of the results achieved. That is the purpose of this framework model f
22、or quality measuring systems. It provides a template of acknowledged best practice within which locally or nationally acceptable systems can continue to be used and developed. This is the best way to proceed as the work of the Technical Committee has established the existence of a wide range of qual
23、ity control systems for cleaning with a variety of features. These have been developed in - response to specific needs or to fit local regulations and laws; in some cases they have a long history of successful use. With the help of this standardized framework model, all systems can be helped towards
24、 greater objectivity and completeness.

29、d and agreed between two parties meet the quality level that is intended to be present according to the requirements expressed explicitly or implicitly in that agreement NOTE In this standard hereafter the quality measuring system is referred to as “the system” 3.2 cleaning performance result of cle
30、aning services and cleaning related services according to requirements NOTE Cleaning services are cleaning activities of a cleaning operative. 3.3 specification document stating the requirements with which the service has to conform NOTE The specification is the part of a contract or service level a
31、greement, that will define the items covered by the system (see IS0 8402:1994, 3.14). e 3.4 item entity or surface (or groups of these) subject to cleaning and cleaning related services and to be inspected (in this standard further referred to as “item”) e NOTE When referring to sampling inspections
32、 an item is called a sampling unit.

33、iterion based on its degree of absence or presence 3.8 acceptance quality limit (AQL) when a continuous series of lots is considered, the quality level which for the purposes of sampling inspection is the “worst tolerable product quality level“ (see IS0 2859-1:1999, 3.1.24) 3.9 average quality of ou
34、tgoing product, material or service, including all lots that have been considered (see IS0 2859-1:1999, 12.3) average outgoing quality (AOQ) 3.10 average outgoing quality limit (AOQL) when a continuing series of lots is considered, the quality level which for the total series of lots is the limit of
35、 a satisfactory average outgoing quality (see IS0 2859-1 :1999, 12.4) 3.1 1 normal inspection use of a sampling plan with an acceptance criterion that has been devised to secure the producer a high probability of acceptance when the process average of the lot is better than the acceptance quality li

38、mitted for examination (see IS0 3534-2:1993, 1.3.5) NOTE All areas composing all or part of one or more buildings, pieces of equipment or installations. 3.1 7 lot-size number of items in a lot (see IS0 3534-2:1993, 1.3.6) 3.18 sampling inspection inspection of selected items in the group under consi

40、ling method of sampling in which the population is divided into mutually exclusive and exhaustive aggregates (or clusters) of sampling units related in a certain manner (see IS0 3534-1:1993, 4.18) NOTE A sample of these clusters is taken at random and all sampling units which constitute them are inc
41、luded in the sample. EXAMPLE When selecting items for inspection a number of areas may be chosen. It is called cluster sampling when all the items within these areas are inspected 3.21 stratified sampling in a population which can be divided into different mutually exclusive and exhaustive subpopula
42、tions (called strata), sampling carried out in such a way that specified proportions of the sample are drawn from the different strata and each stratum is sampled with at least one sampling unit (see IS0 3534-1:1993,4.14) EXAMPLE When for example a random sample of 20 rooms is needed in a building w
43、ith 10 floors, it is called stratification if the building would be divided in clearly defined parts like one stratum per floor. This would in this example lead to randomly selecting two rooms per floor. O BSI 07-2001 Page 7 EN 13549:2001 4 Requirements 4.1 Conditions 4.1.1 The system shall specify
44、what limitations exist onthe kind of service and locations to which it is applicable. 4.1.2 The system shall specify what it covers in the way of cleaning related services. 4.1.3 The system shall provide guidelines to specify one or more levels of quality. 4.1.4 The system shall provide an evaluatio
