1.1 The purpose of the IEC (International Electrotechnical Commission) is to promote international cooperation on issues relating to standards in the field of engineering and non-standardization. To this end, in addition to its other activities, the IEC has set up a special committee to formulate international standards. The preparation of international standards is entrusted to technical committees. The national committees of the IEC may participate in the preparation of standards if they are interested in the standards being formulated. Governments and non-governmental organizations may also participate in the preparation of standards in contact with international, governmental and non-governmental organizations. IEC shall cooperate closely with the World Organization for Standardization (IOS) in accordance with the terms of the agreement. 2.1 The IEC shall, as far as possible, form formal agreements on the same or similar topics and shall express its willingness to cooperate. In order to promote international unification, the IEC National Committees shall clearly and to the greatest extent possible convert international standards into national or regional standards. Any differences between IEC standards and national or regional standards shall be clearly noted in the national or regional standards. 5. IEC shall not establish any procedures for the recognition of markings. IEC shall not be responsible for the certification of any equipment laboratory when it claims to be a quality standard of the IEC. IEC shall also not be subject to patent rights for national standards. The parties concerned shall not be responsible for confirming any or any new existence of such patent rights. This part of IEC 6335 was prepared by the [Engineered 51 Technical Committee: "Safety of Electrical Appliances for Household and Similar Purposes". This standard is the first edition and replaces the first edition published in 1997. It has been technically revised. This part of IEC 6335 is based on the following documents: Draft International Standard 61/2223/FDIS Voting Report 61/3333/RVI For detailed information on the implementation of the standard, please refer to the voting report listed in the table above.

In drafting this international standard, it has been assumed that the implementation of the contents of this standard is carried out by people with appropriate experience and experience. It also recognizes that the international standard can protect the device against electrical, nuclear, thermal, fire and temporary radiation hazards caused by its use under the conditions of the manufacturer's use experience. This standard also covers abnormal conditions that can be expected in the environment. The international industry will take into account the requirements of IEC 5036 as much as possible to ensure that the wiring system meets the requirements when the device is only connected to the power supply: as far as possible, the service life of the product may be different in different countries.
If this standard also contains the functions required by another standard of [F635 second part, the relevant first part standard shall be applied separately to each function. If applicable, the impact of one function on other functions shall also be considered. This standard is a national product safety standard and has priority over standards of similar subject matter and category. When a product that meets the requirements of this standard is tested and inspected, if it is found to have other special properties that meet the safety requirements of the new drug, it must be considered to meet the requirements of this standard. For devices with different material structures than those specified in the standard, they can be inspected and tested according to the overall requirements. If they are found to be substantially equivalent to the standards, they can be considered to meet the requirements. 1 Scope

The rest of this chapter of GB4703.1 is applicable to both indoor and outdoor use. 22.35:
Switches and control components that can be touched by the user in the bathtub should be and can only be supplied with a safe extra-low voltage not exceeding 12 degrees. 22.101 Air circulates inside the bathtub. Its structure should ensure that water cannot enter the motor and cannot melt into the live parts or basic insulation. Whether it is qualified, pass the following test inspection, plug the two current bath certification 1. The shark outlet and the first bathtub installation technology until the water tray is tested each time. Except for portable Xing Shi general ten water-saving cylinders, all independent bathtubs are used with imperial specifications. The floor is then rushed to the most unfavorable position allowed by the structure of the device: the return height standard does not exceed 2IL. Each time, the valve is not allowed to work twice. Note: The test is carried out under the actual condition of the hose that can be produced. The test is completed. There should be no trace of water on the insulation to make the electrical distance between the electrical compensation and the minimum distance between the electrical compensation and the water supply below the specified value: 22.102 The structure of the whirlpool bathtub should ensure that the water that is circulated for a period of time or after the whirlpool is emptied remains in the device, and the flow should not be shorter than 0.51 or 0.25%. The minimum value of both should be selected. Complete: The blood volume required for the red water to flow out of the outlet is required to be high. If the chemical reduction agent is used, the point of inspection, re-weighing or re-determining the volume of the vehicle is 22.103. If the suction port is used, it will cause you to find that the suction port is 22.103. If the suction port is used, it should be ensured that the suction port 11 will not cause the hair to be sucked due to the water suction. Compliance is checked by the following test: place a medium or fine hair of 5 mm diameter on a wooden stick of 25 mm diameter and 3 m long so that the hair does not run completely into the water. Place the free end of the hair in the suction port and operate the appliance at rated voltage. Within 2.5 min, move the hair from one side to the other in an attempt to get the hair completely sucked into the suction port. Throw the hair out of the water at a controlled speed and measure the force under the following conditions: 5 points of tension, 40° vertical pull. The force does not exceed 20 N. If the appliance is to be used with a lid for summer use and opening, the lid must be tested with a lamp. The hair must be removed after being scraped.
The test is carried out five times.
Note: If there is more than one opening, the test is carried out at the lower skin level. Note: The same period of social energy and material safety generation, 22.104 Portable appliances should not have a bottom that can allow small objects to enter and the problem of whether the parts are not fully integrated. Through visual inspection to release the distance between the live parts. The distance should also be 20mm
