This standard specifies hygiene requirements for the design and construction of display containers for unpackaged, mostly ready-to-serve foodstuffs for self-service which do not require cooling in order to be able to offer these foodstuffs in satisfactory hygienic condition. These foodstuffs offered in this manner are dry foodstuffs, such as nuts, nut mixtures, popcorn, cereal mixtures, dry fruit, rolls in nets, sweets, cocoa products, pasta or pulses. The specifications refer to permanently installed equipment. Parts for single use and for disposal are excluded from the scope of this standard. One of the annexes simultaneously provides information about the proper handling of display cabinets. The requirements contained in DIN 10501-3 specify more precisely the general legal provisions with regard to suitable materials as well as hygiene-compliant construction and design of display containers. The user information contained in the annex provides guidance for the setting up and operation of the display cabinets in order to prevent an adverse effect on these foodstuffs. DIN 10501-3 provides, on the one hand, the manufacturers of display cabinets with guidance for the hygiene-compliant design of display cabinets for foodstuffs and is, on the other hand, intended for the orientation of the users, for example, the food industry, in order to comply with the legal provisions. The use of hygiene-compliant display cabinets in connection with proper handling facilitates compliance with satisfactory hygienic conditions during the handling of foodstuffs and thus serves the protection of the user against health dangers. This product standard, which deals in particular with health protection aspects, describes the technical prerequisites and the suitable handling of display cabinets for foodstuffs. The committee responsible for this standard is NA 057-02-01-21 AK "Verkaufsmöbel für Lebensmittel" ("Display cabinets for foodstuffs") of Working Committee NA 057-02-01 AA "Lebensmittelhygiene" ("Food hygiene") at DIN.
