This European Standard specifies requirements and test methods for storage units (see 3.1) used in laboratories. This European Standard specifies strength, durability and safety requirements to prevent serious injury through normal functional use, as well as misuse that might reasonably be expected to occur. Safety, depending on the structure of the building, is not included e.g. the strength of wall hanging cabinets includes only the cabinet and its parts. The wall and the fixing in the wall are not included. It should be understood that the tests do not ensure that structural failure will not eventually occur as a result of habitual misuse or after an excessively long period of service. Assessment of ageing, degradation and the heating effect of appliances are not included nor are ergonomic aspects or resistance to fire.
