1 Scope This clause of part 1 is applicable except as follows: 1.1 Replacement: This standard applies to portable electrical motor-operated spray extraction appliances and electrical attachments employing water-based cleaning agents for cleaning fabrics, upholstery, carpets, floor coverings or hard surfaces, intended for industrial and commercial use. Industrial and commercial uses include, for example, use in hotels, industry, schools, hospitals, factories, shops, offices and in the rental business. Machines with or without electrical heating elements and with or without attachments are within the scope of this standard. This standard covers appliances in which the pressure of the cleaning agent is positive and not more than 25 bars, or in which the product of the pressure (in bars) and the flow of cleaning agent (in litres per minute) does not exceed 1 000, and in which the temperature of the cleaning agent at the spray nozzle outlet does not exceed 85 °C. This standard does not take into account the special hazards wich exist in nurseries and other places where there are young children or aged or infirmed persons without supervision; in such cases, additional requirements may be necessary. This standard does not apply to: - appliances exclusively designed to handle hazardous solvents, such as flammable or explosive liquids; - appliances solely designed for household use; - appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas). For appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary. For appliances intended to be used in tropical countries, special requirements may be necessary. Attention is drawn to the fact that in many countries additional requirements are specified by the national health authorities and the national authorities responsible for the protection of labour.
