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 refinishers 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.NOTEPressure related parts of the machines referred to in this European Standard exceeding the limits 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 foreseen 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 equipment and/or air conditioning inside the mixing cabinet.The mixing machinery may be fixed or mobile.1.2The 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.1.3This European Standard is not applicable to mixing machinery which is manufactured before the date of publication of this European Standard by CEN.
