1) TEC (International Electrotechnical Commission) is a worldwide standardization organization composed of all national electrotechnical committees (IEC National Committees). Its purpose is to promote international cooperation on all standardization issues in the electronic and electrical fields. There are some other additional activities after this, such as issuing IEC international standards. The preparation of international standards for publication is entrusted to technical committees. In this process, any IEC National Committee may participate in the matters of interest. International, governmental and non-governmental organizations also participate in this preparation. IEC and the International Organization for Standardization (ISO) work closely together under conditions determined by agreement between the two organizations. 2) IEC formal decisions or agreements on technical matters are made by technical committees in which all national committees with an interest in these subjects participate, so that they can represent and express as faithfully as possible an international consensus on the issues involved. 3) IEC publishes standards, technical reports or guides for international use in a recommended manner and are accepted by national committees. 4) In order to promote international coordination, IEC hopes that national committees will adopt this IEC standard in their national or regional standards where conditions permit. Any differences between the national or regional standards corresponding to IEC standards and this standard should be clearly pointed out at the end.
5) IEC does not provide an approval process for marking its standards, nor is it responsible for proposing that any equipment conforms to the standard. This standard was prepared by IEC Technical Committee 61: "Safety of Household and Similar Electrical Appliances". It constitutes the fourth edition of IEC 60335-2-10 and replaces the third edition and its amendment No. 1. This standard is based on the following documents:

The appliance is installed with accessories according to the instructions for use. The carpet cleaning machine runs on the carpet, which is fixed to the bottom of the metal plate, and the plate is filled with water. The water level is about 3mm below the upper surface of the carpet. The carpet is made of nylon fiber and the pile height is about 6mⅡ. The floor scrubber runs on a 25mm thick and 100mm wide untreated smooth pine board, which is fixed to the bottom of the gold chip plate, and the plate is filled with water.The water level is about 1 mm above the upper surface of the board.
