This European Standard applies to rooflights and rooflights with upstand, where a single manufacturer provides all components of the rooflight with upstand, which are bought in a single purchase. This European Standard applies to rooflights with one or several translucent parts. Rooflights may be opened by means of opening devices in one or more parts for ventilation. The possible additional functions of day to day ventilation, smoke and heat ventilation e.g. in case of fire in accordance with EN 12101 2, roof access, and/ or slinging point e.g. in accordance with EN 795 are outside the scope of this document. This European Standard does not include calculations with regard to construction, design requirements and installation techniques. NOTE Guidelines for safety, application, use and maintenance of individual rooflights are presented in Annex A.

Food processing machinery. Vegetable peelers. Safety and hygiene requirements

1.1 This European standard specifies the safety and hygiene requirements for the design and manufacture of vegetable peelers used in the commercial and institutional catering industry, and in food shops. The machines concerned by this standard are designed to peel different sorts of vegetables and tubers such as potatoes, carrots, salsify, turnips, celery and onions. The standard is limited to machines where the maximum capacity is 50 kg. The machines are not intended to be moved during operation. The rotating plate mixes the product under appropriate conditions so that the desired operation is carried out on the entire load. This operation can be: - the abrading of the surface of the vegetable or tuber; - the cutting of fine particles of skin if the fitting is of the blade-type; - grating, an operation which is similar to abrading; - scraping or cleaning with a brush, rubber coating or cast iron surface. Machines subject to this standard use water circulation to carry waste to the waste outlet. The underside of the plate is sometimes designed with raised parts which speed up the discharge of the waste water. This European Standard deals with the hazards which can arise during commissioning, operation, cleaning, removal of food blockages, feeding, changing the tools, maintenance and decommissioning of the machine. Machines covered by this standard are not intended to be cleaned by high pressure water jets. 1.2 This European standard does not apply to domestic machines. Vegetable peelers have nothing in common with meat derinding machines (which are dealt with in EN 12355), both from their design and use standpoint. 1.3 This European Standard specifies all significant hazards, hazardous situations and events relevant to vegetable peelers, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). 1.4 Noise is not considered to be a significant hazard for vegetable pee

Household refrigerating appliances. Characteristics and test methods

This International Standard specifies the essential characteristics of household refrigerating appliances, factory-assembled and cooled by internal natural convection or forced air circulation, and establishes test methods for checking the characteristics. These are type tests, and because of this, when verification of the performance of a refrigerating appliance of a given type in relation to this International Standard is necessary, it is preferable, wherever practicable, that all the tests specified be applied to a single unit. The tests can also be made individually for the study of a particular characteristic. NOTE For the safety requirements applicable to household refrigerating appliances, see IEC 60335-2-24, for noise requirements applicable to household refrigerators and freezers, see ISO 8960, and for additional safety requirements applicable to the refrigerating systems of household refrigerating appliances, see in ISO 5149.
