1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization composed of national electrotechnical committees (i.e. IEC members). The purpose of IEC is to promote international cooperation on standardization issues related to the electrical and electronic fields. To this end, in addition to organizing various activities, IEC publishes a wide range of international standards. The drafting of international standards is entrusted to technical committees. National committees interested in the relevant issues may participate in the drafting of relevant standards. International organizations, governments and non-governmental organizations associated with IEC may participate in this drafting work. IEC determines its close cooperation with international organizations for standardization (ISOs) under the conditions stipulated in the agreements between IEC and international organizations for standardization. 2) Formal discussions or collaborations on technical issues are formulated by technical committees participated by national committees with special interests in these subjects, and express international consensus on the relevant aspects as far as possible. 3) Documents published in the form of standards, technical reports and guidelines for international use have the nature of recommendations and are accepted by national committees in this sense.
4) In order to promote international uniformity, the IEC expresses the wish that National Committees adopt the texts agreed upon by the IEC to the greatest extent possible in their national regulations. Any differences between the texts agreed upon by the IEC and the corresponding national regulations shall be clearly indicated in the national regulations.
5) The IEC does not establish any marking procedures for the recognition of any equipment and therefore does not assume any responsibility for any claim that its equipment conforms to a particular TF standard.
6] Attention should be drawn to the possibility that some parts of this International Standard may involve proprietary rights. IEC does not assume any responsibility for the confirmation of any such proprietary rights.
International Standard 173 was developed by Technical Committee No. 16 (Basic and safety rules for marking and identification of man-machine interfaces). This standard is a new technical version of the fourth edition published in 1951 and is a basic safety publication in accordance with IEC Guide 104. This standard version is based on the previous version and the following documents: FDIS

GB/T 4025—20Q3/TEC 60073; 1996 This basic safety publication is prepared for technical committees working in accordance with the general principles specified in IEC 60104 [] and ISO/IEC Guide 51 [2] - Application:
It should be noted that one of the responsibilities of a technical committee is to include or refer to the requirements of basic safety publications wherever possible within its scope. Therefore, the requirements of this basic safety publication are applicable only when included or referred to in those standards. Monitoring and control are essential for the performance of the duties of personnel who monitor or operate electrical equipment. The information presented must meet the needs of users to perform tasks such as monitoring and related operation of industrial processes. Safety and ergonomic requirements should also be considered. A single coding method alone is often not sufficient to ensure that information is conveyed unambiguously. In addition to the clear marking of indicators and operators, the coding system also requires clarity and consistency. The choice of code depends on the information to be expressed, which is related to the status of the equipment (or a part of it), the process conditions and the impact on people, property and the environment under this condition. The user can decide on the code to be used based on the above rules. For the mathematical requirements in the literature, please refer to the requirements in the literature. 1 Standard G8/T40252003/EC60073:199 Basic and safety rules for marking and labeling of human-machine interfaces Code rules for indicators and operators + This standard establishes a general rule for the specific meanings assigned to basic sensory, auditory and fuzzy symbols. Its purpose is to: improve the safety of people, property and/or the environment through the safe monitoring or operation of equipment or processes. To facilitate the normal monitoring and maintenance of equipment or processes. This standard is applicable to the following occasions: From some simple occasions such as single indicator lights, buttons, micro-indicators, light-emitting diodes (LEDs) or graphic display screens to various control stations composed of various devices used to control various inputs or industrial processes. It also combines personal, property and/or environmental safety, and uses the above code to monitor the equipment. The occasions where a specific code is specified by the technical requirements for a specific function include: sending, the book is concerned with the color mark, the power industry does not implement it, 2 Normative reference documents The clauses in the following documents become the clauses of this standard through reference in this standard.

Color and time-varying elements (flicker) are provocative ways to attract attention. Therefore, these codes should have consistent meanings, preferably using color, and flashing to attract attention. GB/T4025-2003/EC60073:1996
When people with color vision impairment are assigned to work, it is recommended that color should not be used as the only means of coding. When the meaning of the color represents involves In the event of a personal or environmental emergency (see 4.2.1.1), an auxiliary coding method should be provided. If the specified color is not allowed for this service recording, a code for an alternative color should be provided (see 4.2.2 and the following sub-clauses of Chapter 4).
azole; auxiliary, other codes are converted into \supplement\ (such as using an augmented state to fill the vibration package), and the code is represented by its partial code as "busy* (such as using a system code to collect the general package). 4.2.1 Color coding
For some specific vibration colors, soft standard meanings are given (see Table 2), which are easy to identify and distinguish from the background color and other given colors: some vibration colors are used exclusively in safety occasions. For the sake of clarity, the vibration colors used in certain applications are The number of colors should be kept as short as possible. For the sake of clarity, the indicators and operating parts covered by this standard only include the following colors: red, yellow, green, blue, black, gray, white, etc. Note that this standard may also be used for indicator sets, such as the supplementary numbers on the indicator groups of the indicator core. In addition to using hue as the main color code, saturation and turbulence sensing can also be used to express more information about these colors. When color is used as the only code, the number of specific colors of indicators and operating parts under the specified operating conditions and during the expected service life should not exceed the recommended range. The specific definition is as follows: Surface color: 1503R61 Emission: C Publication No. 2-2 The color you see is the combined effect of the emitted light (such as the light alone) and the radiation from the person working with the light. Compared with the unspecified color in 250854, 4.2.1.1 Choice of color The meaning of color information is given in general by Table 2. #2 Color code - General principles Safety of personnel or environment, black, white, attention to directive meaning, specific meaning of the source, equipment, etc. If the ten parallel indicators of the time information source are installed in different places, they may have different meanings. These indicators can use different packages (see Appendix B).
If it is not fair to the operator, the color can be displayed by gas discharge lamps and non-color light-emitting diodes (1.E). If light-emitting diodes are used to display at least two of the colors white, black and green at the same time, special attention should be paid to avoid confusion:
The color displayed by the indicator is selected according to the information it conveys. At the same time, the meaning of the color should be determined according to the order of the following monitoring criteria,
Human body changes environment!
—Process status,
Equipment status,
Should be in accordance with the meaning given in the table, select the color code according to one of the above criteria, without causing any confusion between the meanings in this table 5
GR/T 4025-—2003/TEC60073:1996, can be clearly determined, 4.2. 1.2 Display screen package
In this standard,Colors used to convey information shall comply with 4.2.1 and their meanings shall comply with 4.2.1.1. The colors on the display shall have sufficient contrast with adjacent colors and the display background. The meaning of each color in a display shall be consistent with that of other related instrumentation and display terminals. For the content of the display, the colors shall be bright, saturated and have high contrast. For secondary information, the colour may be darker and less conspicuous. 4.2.7.3 Contrasting colours If contrasting colours are required in safety applications, between indicators or operating surfaces, they should be used in combination. However, for red stop switches, yellow may be used as a contrasting colour. Note: For emergency stop switches, yellow may be used as a contrasting colour. 4.2.2 Shape and/or position codes and key position codes are used in the following situations: a) as a primary code
as a supplementary code to the primary code used, such as shape codes as a supplement to colour codes, which can avoid misidentification caused by the colour vision of the individual. b)
The specific shape should be given its meaning (see Table 3), position coding, and the main committee should apply the indication of the process status and equipment status (see TE61447). It is recommended to use a graphic number, for example: on the basis of 1EC6C027GR/T5165, G/T1725 or GB/T: 6273.1, supplement the relevant equipment status (see Table 8). The meaning of the shape coding is the safety of the room and the environment. The double sign of the process status or equipment is also in accordance with the waiting code in G3/T3463, CB/T4726 and CB/T16273.1, only for the shape that is different from the safety. GB/T 4025—2003/1EC 60073,1996 When shape is the only way to indicate the use of the sign, the size of the shape and the contrast with the background should be consistent with the intended use of the sign. Method: In signs, graphic symbols can convey specific information, and when the meaning of the shape is related to the safety of the equipment, the supplementary information provided by the symbol is 4.2.3 Time-varying abbreviations 4.2.3.1 General A feature that changes with time can be used to provide information. For example, in the following applications, to attract attention, especially to further emphasize information, a feature that changes at any time can be used. a) Requires rapid response (see Note): 1) Measures to indicate the difference between the command state (indicated state) and the actual state of the equipment! ) indicates the change of the pulse rate (flashes during the transition period) Note: The information transmitted by the flashing device is selected as a flash and becomes a heat wave. 4.2.3.2 General characteristics of flashing frequency
Two flashing frequencies and can be used. The highest priority should be to use a higher flashing frequency (such as: the box is out of the information!, clearly understand the reason for the handshake)
The allowable range of flashing frequency is as follows:
- Slow flashing frequency, 0.4Hz2~0.8H (24~8 flashes per minute) - F: Normal flashing frequency, 1.4Hz~2.8Hz [84~163 flashes per minute). When only one internal flash rate is used, the ratio of the flash rate to the flash frequency should be a constant for a given application and should be less than 1:2.5, but should be rounded to 15. The recommended ratio is 1:4 (for example, the frequency is 0.5Hz or 2Hz). The recommended ratio of pulse to time is approximately 1:1, that is, the light time should be equal to the non-light time. For , the light time can be longer than the non-light time and for , the light time is shorter than the non-light time. However, the ratio of pulse to time should not exceed 2, and for f. The ratio of pulse to time should not exceed 1.2. Note: For flashes, it is recommended to use background flashes to replace the internal flash. If it is possible to record, it is recommended to use the flash time equal to twice the non-light time.
4.3 Auditory Codes
Audio codes can be used in the following situations:
Need to attract the attention of the crime personnel!
Use code to indicate brief, simple and continuous information; the information expressed requires immediate or time-dependent response - the application of visual codes is limited:
In dangerous situations, it is necessary to use an additional or repeated auditory signal including pure (single tone, noise or verbal information). The auditory signal can indicate the start and duration of the danger or warn of the imminent danger.
The auditory signal should be easy to recognize and can be heard by people within the predetermined reception range of the signal and under the sound conditions of the project environment. It can also be heard under the sound conditions of the project environment. This auditory signal should be clearly distinguishable from the emergency signal (GB/112899). And the company's audible signal should be clearly distinguishable. The general rules for the auditory codes for hearing impairment and other hearing-impaired conditions, such as wearing ear defenders and headphones, are given in Table 4. GD/T4025-2003/IEC60073;1996 In order to prevent the operator from being overexposed to the sound, the number of different sound types used in the given application should be limited to a minimum.

Codes that convey information to operators through touch are used in limited situations, for example, to remind operators to pay attention to dangerous situations when operating equipment.
Tactile information should be able to be correctly identified by the operator when operating the equipment/equipment in the specified way. Tactile codes are designed for use by trained/trained personnel. Tactile codes for pending information should only be used when there is a guarantee of direct and continuous contact between the indicating device and the human part.
