IEC Foreword
1) IEC (International Electrotechnical Commission) is a world standardization organization composed of national electrotechnical committees (IEC National Committees). The purpose of IEC is to promote international cooperation on all issues related to standardization in the electrical and electronic fields. For this and other activities, IEC publishes international standards. The preparation of standards is entrusted to technical committees, and any IEC national committee interested in the subject may participate in its preparation. International, governmental and non-governmental organizations in contact with IEC may also participate in the preparation of standards. IEC and the International Organization for Standardization (ISO) cooperate closely on terms agreed by the two organizations. 2) IEC decisions or agreements on technical issues are made by technical committees represented by all national committees with special interests in these issues, and express international consensus on the issues mentioned as far as possible. 3) Documents are published in the form of standards, technical reports or guidelines for international use in a recommended manner and are accepted by national committees in this sense.
4) In order to promote international unification, IEC national committees have the responsibility to apply IEC international standards to their national and regional standards to the greatest extent possible. Any differences between IEC standards and their corresponding national or regional standards should be clearly stated in the national or regional standards. 5) IEC does not provide a method of marking approval for any equipment claiming to comply with IEC standards and is not responsible for it. The international standard IEC61310-2 was originally developed as EN50099-2 by CENELEC (European Committee for Electrotechnical Standardization) Technical Committee 44X in cooperation with CEN (European Committee for Standardization) Technical Committee 114 and has been adopted. This standard was developed by IEC/TC44: Machinery Safety - Electrotechnical Field under the "Fast Track Procedure". This standard has the status of a horizontal standard and can be used, for example, as a reference standard in ISO and IEC technical committees developing machinery product series standards or special product standards. Machinery suppliers can also adopt the technical requirements of this standard for machinery that does not have a product series standard or special product standard. Where a product series standard or special product standard exists, it shall be adopted first. The text of this standard is based on the following documents:

5.1 General
Machinery and parts of machinery whose installation or reinstallation may cause risks should be marked with rating plates, nameplates, labels, stamps, engravings and colors. Such markings should be considered for the delivery of integral parts of machinery. Any markings on the equipment should be consistent with the accompanying documents to avoid confusion. Markings, symbols and textual information shall be easily understood and unambiguous, especially for parts or functions related to machinery. Graphical symbols shall be used in preference to textual information, and shall be selected from standards GB/T5465.2-1996 or ISO7000 (see Annex A) as far as possible.
Textual information shall be in the language of the country in which the machine is used and, if required by the user, in a language easily understood by the operator and exposed persons. If there is no sufficient space for legible writing or marking on machinery or equipment, including consumables, at least the prescribed information shall be provided on the packaging of the distributed items.
Marking shall be clearly visible when the machinery is installed in the manner specified by the manufacturer. If this is not possible, additional markings or warnings shall be placed close to the machinery in such a way that they are visible to exposed persons. Markings at all stages of the "life" of the machinery shall be permanent and always legible (see 3.11 of GB/T15706.1-1995). See also clause 7.
All equipment shall be packaged in such a way that the markings on the equipment remain during transport. NOTE
1IEC60750 defines the general principles for the structure of equipment information. In any system, guidance is given according to these principles for the composition and use of discrete object item codes.
Specify different types of file items and related information for achieving installation purposes. For ease of maintenance, all or part of the item code may be indicated on or near the item in the equipment.
2ISO/IEC Guide 37 provides information in the product manual that users are concerned about. 5.2 Ratings
The International System of Units (SI) proposed in GB3101 should be used. For more detailed application guidance, see IEC60027-1, IEC60027-2IEC60027-3, IEC60027-4 and GB3100. Machinery should be marked with the rated values ​​of the relevant safety characteristics, such as: - input or output power, in watts; working pressure, in Pascals;
Instructions for use:
1]d flow rate, IEC61310-2 English is flowrate. * Within the scope of ISO/TC131.
- power supply voltage, in volts;
- maximum speed in revolutions per minute. GB18209.2—2000
Each rated value mark consists of the characteristic value and the unit symbol after it. Machinery applicable to more than two discrete rated values ​​should be marked: - rated values ​​separated by slashes in descending order; - units are represented by symbols.
For example: 3000r/min/1500r/min/750r/min10MPa/5MPa/2MPa
Applicable to machinery within the rated value range: - Limit values ​​are separated by three dots in ascending order; - Units are represented by symbols.
For example: 1000r/min~1500/min
-20℃~+20℃
100Hz~400Hz
200Pa~500Pa
6 Connection marking
6.1 General
All connectors must be marked to ensure the correct connection of the equipment. Connectors that can be quickly separated and replaced, and connectors whose models and structures may cause danger if they are connected incorrectly, should be selected or configured to ensure correct connection. If this is not possible, use distinguishing marks. Color coding is only an auxiliary method. 6.2 Mechanical connections
Sometimes it is difficult to prevent the wrong connection of mechanical parts, so these parts should be marked to indicate the correct connection method. When it is necessary to identify the lifting rings and alignment marks during the installation and removal of the machine, the meaning of these marks should be explained in the accompanying documents. 6.3 Hydraulic system connections
Connection paths, power output devices (test connections, drainage points) and discharge ports (such as container outlets) are clearly distinguished by markings. The markings correspond to the data on the circuit diagram. If color coding is used, the meaning of the colors is given in the accompanying documents. 6.4 Electrical connections
The markings for electrical connections are as follows:
—Bare conductors and insulators, in accordance with the provisions of 15.2 of GB5226.1-1996; —Terminals, in accordance with the provisions of 5.1, 5.2 and 15.1.1 of GB5226.1-1996; —Plug and socket connections, in accordance with the provisions of 15.4.5 of GB5226.1-1996. 7 Durability of marking and its connection
The marking shall maintain the following during the entire mechanical life: a) a firm connection;
b) clear writing;
c) long-lasting color;
d) resistance to damage caused by environmental factors (such as liquids, gases, climate, salt spray, temperature, light); e) wear resistance;
f) dimensional stability.
The test methods for the above requirements shall be in accordance with the provisions of the relevant product series and/or special product standards (Class C standards for mechanical safety as described in GB/T15706.1).
