BS EN 12757-1:2005+A1:2010EN 12757-1:2005+A1:2010 (E) 4 Introduction This European Standard is a C type standard as stated in Parts 1 and 2 of EN ISO 12100. This European Standard is part of a series of documen

22、ts specifying the health, safety and environmental protection requirements for the devices, units and equipment for surface coating: EN 1953 “Atomising and spraying equipment for coating materials Safety“; !EN 12621“ “Machinery for the supply and circulation of coating materials under pressure Safet

23、y“; EN 12757-1 “Mixing machinery for coating materials Safety“. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard. NOTE Further parts of this European Standard to cover other mixing machinery appl

24、ications for coating materials may follow. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built acc

25、ording to the provisions of this type C standard. BS EN 12757-1:2005+A1:2010EN 12757-1:2005+A1:2010 (E) 5 1 Scope 1.1 This European Standard applies to the design and construction of mixing machinery for liquid coating materials equipped with container of maximal volume 10 l used by vehicle refinish

26、ers and their coating materials distributors. The pressure related parts of the machines covered are classified as no higher than category I under article 9 of the Pressure Equipment Directive 97/23/EC. NOTE Pressure related parts of the machines referred to in this European Standard exceeding the l

27、imits of category I may lead to additional application of the Pressure Equipment Directive 97/23/EC. This European Standard deals with all significant hazards, hazardous situations and events relevant to mixing machinery mentioned above, when they are used as intended and under the conditions forese

28、en by the manufacturer (see Clause 4). Mixing machinery can operate by stirring or vibrating (shaking) and consists of the following equipment: cabinet; stirrer; vibrator; shaker; drive unit and related devices; container for coating material; safety, measuring and control devices; lighting; heating

29、 equipment and/or air conditioning inside the mixing cabinet. The mixing machinery may be fixed or mobile. 1.2 The following is excluded from this European Standard: Mixing machinery intended for: pressure vessels; open or closed material containers larger than 10 l; hand-held mixing tools. 1.3 This

30、 European Standard is not applicable to mixing machinery which is manufactured before the date of publication of this European Standard by CEN.

45、c areas 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 971-1:1996, EN ISO 12100-1:2003 and the following apply. 3.1 mixing machinery machine for the mixing by stirring (with an inside agitating device), or by vibrating or shaking (by motion

46、of the container) of liquid coating materials in containers (vessels without pressure) NOTE 1 In a container, in which two or more components of which at least one is in a liquid consistence are brought together to be processed to a liquid coating material for vehicle refinishing use. NOTE 2 In gene

47、ral, the mixing machinery consists of a cabinet (as framework) with several shelves on which the mixing places are arranged. The number of shelves and mixing places depend on the volume of the container. The mixing places could be occupied by container of standardized mixing coating materials with a

48、 capacity between 1 l and 10 l. The container is closed by a stirring lid. The stirring lids generally consist of a unit with stirrer, lid and drive (e.g. clamp or rack-wheel) which are put on the open container of the coating materials. The lids are fixed by the pressing and turning of fixing clamp

49、s and ensure mixing process only in totally closed container. The stirrer can be powered e.g. via a clamp drive by a motor powered special shaft or via belt or worm drive. In general this is an electric motor, but also air driven motors are used, especially for installations in hazardous explosive environments. Furthermore the mixing machinery is equipped with a contro
