This part of GB/T 2423 specifies the test method for determining the resistance of markings and printed text on flat or curved surfaces to wear, which may occur on manually operated actuators and keyboards. This test can also be used to determine the resistance of markings and printed text to wear that may be affected by fluid contamination under normal use.

This part is an informative appendix
This part was proposed by the Ministry of Information Industry of the People's Republic of China. This part contains all the key members of the Henan Provincial Electrical and Electronic Product Environmental Technical Standards Committee. The starting units of this part are: the Fifth Research Institute of the Ministry of Information Industry, the main drafters of this part are Gong Zhong, Zhang Zheng and Zhang Shuibin. CB/T2423.53—205/IEC60068-2-70:2995 Introduction This part of CB/T2423.53 specifies the test method for evaluating the resistance of printed characters on certain parts of electrical products (such as switches, plugs, operating handles or buttons) to the influence of fingers or other parts of the hand. This part is also applicable to other electrical products. When the friction to which the product is subjected in normal use is too great or the clarity of the marking is important due to the "safety" or other conditions, this test is used: 1 Specification!

(This part specifies the test method for determining the resistance of markings and printed text to abrasion caused by friction with hands. It requires manual simulation of the movement of the drive and keyboard. This test does not cover markings and printed text that may be affected by dirt under normal use.) 2 Normative documents
The clauses in the following documents shall become effective as of the date of this part. All subsequent editions, excluding errata or revisions, are not applicable to this part. The parties hereto shall discuss whether the reverse versions of these documents may be used. Any revisions not specified in this part shall apply to the latest editions of this part.
GE/2-211999 Environmental testing of electronic products Part 1: General [EC60061 :19Favronme:atasng-Par:J,Cirneraiaudguidansc.IDT)3 The test surface should be subjected to the stress produced by the movement of the test surface. The active chamber has only elasticity and is in contact with the test surface through deformation. The material, hardness, shape, movement and angle of motion of the active seat should be selected according to the conditions of pressure and lifting. A piece of fabric should be placed between the active seat and the test surface, either as a cover or as a curtain. The piston and the blood on the surface of the inspection can be avoided by the object (under the test), or in order to prevent the use of the specified test filter body foam fabric under the case of fluid contamination! Virtual test), this cabinet is indeed the relevant standard. The above test device
4.1 Test equipment
Type test equipment is shown in the medical record 4,
The test equipment is tested by the movement of the rod for a period of 15°1=. The standard is used as F! The relevant standard is to make the test piston produce elastic deformation, and the test is required to be tested. The risk of producing rubber movement rate case 5: the amount is 1%m rate m. The US specification should specify the extrusion energy ring as the natural source
For non-rigid test samples: such as keyboards) the relevant specifications should stipulate H additional safety requirements (such as the specified), the test case with the test liquid does not produce this effect of degradation of the village material, its A type civil resistance should be? [IA5IIA (such as synthetic fast policy):
The size of the test station can be selected according to the shape and size of the test sample and the information of the printing and text Ning in Table 1: Scan the US specification to say the size of the test case. If you need to choose the difference test For other pistons with smaller sizes, the relevant specifications for testing samples are as follows: "Test samples shall be tested according to the following standards: The test results shall be tested according to the following standards: GH/T2423.53-2005/IR:69368-2-70:1995 Table 1 Applicability category and size 4.2 Test motion Ftmur u
In the test room and test pieces, the fabric should be replaced in the test room. The fabric should also be removed and the whole fabric should be moved in the test room. Material:
Feed line dm line/ru
Load: 135 line/m Weight: Gm:
Unit national area mass: 2105g
"During the test, in order to avoid scratches, new fabric should be replaced after a maximum of 300 cycles. The fabric should be moved quickly so that the relevant parts are in contact with the test sample.
"Wet test During the test (see 4.3), the fabric shall be soaked for 10 cycles or the fabric shall be moved so that part of the fabric is moved between the test samples. During the soaking, the fabric shall be cooled or the test liquid shall be dripped onto the fabric regularly. The fabric shall be replaced after each new test after 10,000 cycles to avoid damage to the fabric due to replacement. 4.3 Test body

b Severity level
The severity level is determined by the magnitude of the force acting on the test sample or the number of times it is applied: it can be selected from the following values. The corresponding standard specifies the selected value, the minimum value of

Section 8 Test conditions
GB/T2423.53—2005/1EC:60068-2-7Q:1995 Unless otherwise specified in the relevant specifications, the following "dry test" should be carried out in accordance with the standard of GB/T2421. The test sample of the specified structure is tested under the action of the test device (see 1.1). The test object moves towards the mountain to be tested at a speed of 6 and acts on the surface of the tested structure with a selected force. , the test conditions shall be selected so that the time of "the active package rubbing against the tested surface" is consistent with the time of "the active package lifting", the force shall not be less than?, the number of times (2U.5) times/second, the relevant specifications may make other frequencies: salt: higher frequencies may cause the sample to produce a small amount of ingested juice. 9 Intermediate testing
Relevant specifications may require in-house testing,
Relevant specifications may require recovery.
11 Post-test
The test sample shall be visually inspected, The old ship standard has the idea of ​​setting rules and also needs to be carried out, and the kinetic energy side of the release is taken, the relevant specifications provide for the selection of products for testing. Or the acceptance judgment,
2 The relevant specifications should make provisions
When the agent standard adopts the monthly form, the following provisions should be made as much as possible: These provisions are required in the following corresponding clauses, and I must pay attention to the appropriate amount of killing teaching, which is a total of one part. It needs to be clearly defined. a)
