This standard describes a system for establishing and assessing cleaning quality. It is based on the general principles stipulated in EN 13549:2001.
The standard describes two main principles: visual inspection, see Clause 4 and inspection using measuring instruments, see Annex D. For a certain cleaning task, it may be preferable to use either the former or the latter principle or a combination of both.
The instrument measuring methods may work as a supplement for special types of premises used for e.g. the production of electronics, pharmaceuticals or food, or for premises housing laboratories, etc. where customers will stipulate special quality requirements or in relation to which there are statutory requirements that shall be observed.
The indoor air quality is particularly affected by dust. In order to achieve an acceptable indoor air quality, it may become necessary to stipulate special requirements as regards dust. This is done by using dust measurements. Customers have the option of defining dust measurements, as described in Annex D.1 only, or as a supplement to the visual inspection. Customers have to specify when measurements shall be taken and the dust level acceptable in accordance with Table D.1.
The standard can be used in all types of buildings and localities, e.g. all types of premises in office buildings, hospitals, schools, nursery schools, shopping centres, shops, production halls, ships, buses, trains, aircraft, hotels and restaurants, irrespective of the cleaning methods, frequency or system used. The standard describes the result achieved immediately after cleaning has been completed.
