It is intended to guarantee consumer protection, minimize the hygienic and toxicological risks (see annex A) and avoid reduction of food quality. 1 Scope This European Standard specifies the thermal and hygienic requirements and test methods for transport units used for short-time transportation of catering containers. Foodstuffs are packaged in these catering containers, complying with EN 631-1, which are fitted with a cover (e.g. lid) to prevent spillage. This standard is applicable for local and short-time delivery only. NOTEAttention is drawn to the EU-directives mentioned in annex B. 2 Normative references This European Standard incorporates by dated or undated reference provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. ISO 4287:1997, Geometrical Product Specifications (GPS) Ð Surface texture: Profile method Ð Terms, definitions and surface texture parameters ISO 4288:1996, Geometrical Product Specifications (GPS) Ð Surface texture: Profile method Ð Rules and procedures for the assessment of surface texture 3 Definitions For the purposes of this standard the following definitions apply. 3.1 transport unit movable equipment with or without additional thermal maintenance to hold catering containers in order to transport them 3.2 local and short-time transportation movement of a transport unit from the preparation area to the consumer area within 3 hours 3.3 food area area composed of surfaces in contact with foodstuff NOTE 1The food area also includes the surfaces with which part of the foodstuffs may come into contact under intended conditions of use, after which they may return into the foodstuffs. NOTE 2The catering container, covered with a tight lid, is a food area. 3.4 splash area area composed of surfaces on or along which parts of foodstuffs may splash or flow under intended conditions of use and do not return into the foodstuffs NOTEAn example is the inside area of the transport unit when the lid or door is shut with the catering containers removed. 3.5 non-food area any area which is not intended to come into contact with foodstuffs and is not a splash area 3.6 cleanable designed and constructed so that soils are removed by recommended cleaning methods 3.7 disinfection inactivation of pathogens and other micro-organisms to achieve hygienic conditions 4 Requirements 4.1 Materials Materials shall be resistant to foodstuffs and normal wear and tear. Surfaces of materials and coatings shall be durable, cleanable and, if necessary, shall be capable of being disinfected. They shall be in a sound condition (e.g. have no breaks, cracks, or strikes) and be resistant to cracking, chipping, flaking and abrasion and prevent penetration of unwanted matter under intended use. The materials shall be resistant to appropriate cleaning substances and disinfecting agents. The materials: Ð shall not transfer undesirable odours, taste, colours or taint to the foodstuffs; Ð shall not contribute to the contamination of foodstuffs or have any adverse influence on the foodstuffs. 4.2 Design and construction 4.2.1 General All surfaces including all removable parts, when fitted, shall be accessible for cleaning and disinfection. Moreover, their assembly shall allow liquids to drain off completely from the outside of the transport unit (in an inclined position, if necessary); if this is impracticable due to weight restrictions, an effective drainage system shall be provided.

The arrangement of the surfaces shall be such that no product particles (foodstuffs or cleaning product) can become trapped in small crevices becoming difficult to dislodge and so introducing a contamination hazard. Adjacent continuous, inner surfaces and corners shall have a minimum radius of 2 mm. Joints between inner surfaces (e.g. side and base) shall be made in the vertical sides at a suitable distance from the base radius. The joints shall be continuous, smooth and free of crevices. 4.2.3 Non-food area All equipment shall be designed and constructed in such a manner as to prevent the retention of moisture, ingress and harbourage of vermin and soils and to facilitate inspection, servicing, maintenance, cleaning, handling and transportation. Tubular framing shall be totally closed, effectively tightened or sealed. 4.3 Thermal characteristics Transport units shall meet the following thermal requirements independent of their materials and design and regardless of the way in which maintenance of the inner temperature is achieved. During and after 3 h transport at the ambient temperature stated in 5.1, the temperature of the contents of each catering container shall comply with the values given in Table 1. Table 1 Thermal class ConditionBehaviour of temperature AHot# 10 K decrease BCold# 4 K increase CDeep frozen# 4 K increase For the cold condition, the temperature of the contents shall remain within +3 8C and +7 8C. These requirements shall be verified by use of the tests described in clause 5. 5 Test of thermal characteristics 5.1 Test conditions Transport units shall be preconditioned at an average ambient temperature of (25±0,5) 8C, with a maximum dispersion of 2 8C. This temperature is the arithmetic mean of the temperatures of two probes located at 0,10 m from the geometric centre of the inner surfaces of two external adjacent walls of the transport unit; it shall be placed at least 0,20 m from the ground. The tests shall be carried out in still air defined by a stirring up rate between 10/h and 20/h. NOTEStirring-up rate = air flow (m3/h)/volume of the test room (m3), measured in normal atmospheric conditions. For insulated transport units with additional thermal maintenance, the additional thermal maintenance means shall be fitted in accordance with the manufacturer's requirements as given in the instruction handbook before starting the measurement. 5.2 Preparation The transport unit shall be loaded in such a way that the ratio between the volume of the test load and the inner volume of the transport unit is equal to (50±5) %. If not otherwise stated, the test medium shall be water. For the test load, a minimum number of catering containers ± made of stainless steel ± shall be used. The containers shall have the same size and the test load shall be distributed equally. The catering containers filled with the test medium and their lids shall be preconditioned at a temperature of: a) 2 8C higher than the initial reference temperature (see 5.3), with a maximum dispersion of 1 8C, for hot conditions; b) 2 8C lower than the initial reference temperature (see 5.3), with a maximum dispersion of 0,5 8C, for cold conditions and for deep frozen conditions. The measuring test points shall be located at the geometrical centre of the test load of each catering container. Immediately prior to the measurement, the transport unit shall be closed. 5.3 Measurement The measuring points shall be located at the geometrical centre of the test load of each catering container. The accuracy of the temperature measurement instruments shall be # 0,5 K. The lids and doors of the transport unit shall be kept closed during the test. a) Hot conditions Ð Initial reference temperature: 75 8C Ð Final reference temperature: 65 8C b) Cold conditions Ð Initial reference temperature: 3 8C Ð Final reference temperature: 7 8C c) Deep frozen condition The tests shall be carried out with diluted glycol (50 % glycol, 50 % water) instead of water. Ð Initial reference temperature: 222 8C Ð Final reference temperature: 218 8C The test results are positive if the temperatures of the contents of all catering containers remain within the indicated values (see 4.3) during the test time of 3 h.
