This European Standard
18、 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of an identical text or by endorsement, at the latest by November 2001, and conflicting national standards shall be withdrawn at the latest by November 2001.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 CEN/CENELEC Internal Regulations, the national stand
19、ards 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 the United Kingdom. The annexes
20、 A, B and C are informative. Introduction 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 should be used. There has been, until
21、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 for quality measuring systems. It
22、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 quality control systems for cleaning
23、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 greater objectivity and completene

28、 management and quality assurance Vocabulary 3 Terms and definitions For the purposes of this standard, the following terms and definitions apply: 3.1 quality measuring system inspection system designed to assess whether the services defined and agreed between two parties meet the quality level that
29、 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 cleaning services and cleaning related services according to r
30、equirements 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 agreement, that will define the items covered by the system
31、(see ISO 8402:1994, 3.14). 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”) NOTE When referring to sampling inspections an item is called a sampling unit.Page 5 EN 13549:2001 BSI 07-
32、2001 3.5 area group of items located within a spatial unit 3.6 qualitative criterion stated characteristic result of a service required according to the specification 3.7 quantitative scale of judgment acceptance threshold for a qualitative criterion based on its degree of absence or presence 3.8 ac
33、ceptance 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 ISO 2859-1:1999, 3.1.24) 3.9 average outgoing quality (AOQ) average quality of outgoing product, material o
34、r service, including all lots that have been considered (see ISO 2859-1:1999, 12.3) 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 a satisfactory average outgoing quality (see ISO 2859-1:
35、1999, 12.4) 3.11 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 limit (ISO 2859-1:1999, 3.1.20) 3.12 tightened inspection use
36、 of a sampling plan with an increased discriminatory ability than under a corresponding plan for normal inspection 3.13 reduced inspection use of a sampling plan with a reduced discriminatory ability than under a corresponding plan for normal inspection 3.14 population totality of items under consid
37、eration (see ISO 3534-2:1993, 1.3.1) 3.15 subpopulation defined part of a population (see ISO 3534-1:1993, 2.5)Page 6 EN 13549:2001 BSI 07-2001 3.16 lot definite quantity of some product, material or service, collected together and submitted for examination (see ISO 3534-2:1993, 1.3.5) NOTE All area
38、s composing all or part of one or more buildings, pieces of equipment or installations. 3.17 lot-size number of items in a lot (see ISO 3534-2:1993, 1.3.6) 3.18 sampling inspection inspection of selected items in the group under consideration NOTE Sampling inspection also refers to whole-lot inspect
39、ions. 3.19 simple random sample sample of n sampling units taken from a population in such a way that all possible combinations of n sampling units have the same probability of being taken (see ISO 3534-1:1993, 4.9) 3.20 cluster sampling method of sampling in which the population is divided into mut
40、ually exclusive and exhaustive aggregates (or clusters) of sampling units related in a certain manner (see ISO 3534-1:1993, 4.18) NOTE A sample of these clusters is taken at random and all sampling units which constitute them are included in the sample. EXAMPLE When selecting items for inspection a
41、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 subpopulations (called strata), sampling carried out in such a way that spec
42、ified proportions of the sample are drawn from the different strata and each stratum is sampled with at least one sampling unit (see ISO 3534-1:1993, 4.14) EXAMPLE When for example a random sample of 20 rooms is needed in a building with 10 floors, it is called stratification if the building would b
43、e divided in clearly defined parts like one stratum per floor. This would in this example lead to randomly selecting two rooms per floor.Page 7 EN 13549:2001 BSI 07-2001 4 Requirements 4.1 Conditions 4.1.1 The system shall specify what limitations exist on the kind of service and locations to which
44、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 evaluation plan for all types of inspection within the system. 4.1.5 The syst
45、em shall provide guidelines to specify categories of areas or items (e. g. offices and sanitary). NOTE When referring to sample inspections these categories are called subpopulations. 4.2 Inspection 4.2.1 Items of inspection 4.2.1.1 Items within the system shall be clearly identified and defined. 4.
46、2.1.2 The system shall give guidelines on how a list of items for inspection shall be made up. NOTE This list itself could be all items which are covered by the specification; or it could be a list of items which are excluded by the specification. 4.2.2 Criteria 4.2.2.1 The system shall specify for
47、each item what are the qualitative criteria to be employed in inspection. The system shall specify for each qualitative criterion a quantitative scale of judgment.
