1G/T2878--·1997
This standard is equivalent to British Standard B55131 Test Methods for Footwear and Footwear Materials Part 6: Implementation Rules, BS51316.1--1981 (92) "Implementation Rules for Comparative Evaluation of Material Components or Structures for Wearing Tests" and BS51316.2--1979 (92) "Identification of Major Design or Construction Defects of Footwear During the Test and Implementation Rules for Suitability Evaluation", and mainly edited the text. The formulation of this standard fills a gap in the shoe fitting rules of my country's rubber shoe industry. Appendix A and Appendix B of this standard are the standard notes. This standard was proposed by the Technical Supervision Department of the Ministry of Chemical Industry of the People's Republic of China, and this standard is under the jurisdiction of Shanghai Rubber Shoe Research Institute, and this standard is drafted by Shanghai Rubber Shoe Research Institute. The main drafter of this standard is Qiu Qiyun.
HG/T 2878—1997
These implementation rules are formulated directly by the Clothing Standardization Committee based on the requirements of consumers, retailers and shoe manufacturers who require the establishment of an executable general procedure for wear test evaluation of new processes, materials and components, structures and designs, styles, etc. for footwear.
Generally speaking, this wear test is used to evaluate new upper and base materials, discuss the relationship between wearing performance and laboratory test results, and judge the impact of component changes or process changes. 1CS 61.060

HG / T 2878 — 1997
This standard establishes a test method to help shoemakers to directly compare and evaluate the wearing of similar footwear or footwear with set performance that adopts new processes, new materials and components, structural design, etc. It stipulates the type, number, selection of wearers, length of wear period of the test and the evaluation procedure of whether the footwear can successfully complete the test. This standard applies to all kinds of boots, shoes, sandals, slippers, etc. 2Definition
This standard adopts the following definitions
2.1 Test subjects: wearers of footwear during the test period. 2.2 Wearing day: about 8 hours of wearing time (continuous or discontinuous) 2.3 Activity cycle: a period of time for special sports and activities 2.4 New footwear: shoes made of new materials, new processes, new styles, etc. 2.5 Controlled footwear: shoes made of known performance, materials and processes, etc. 2.6 Defects: deviations in design structure and process lead to failure in wearing. 3 Test method
At least 6 pairs of shoes are used for testing, preferably including a series of shoe sizes. 3.2
Selection of test subjects
3.2.1 Test subjects should be selected to wear continuously and to have their shoes taken back after the trial. 32.2 Test subjects whose shoes show abnormal phenomena when worn must be rejected. 3.2.3 The selection of test subjects includes gender, approximate age and occupation. For footwear used for specific self or specific activities, the test subjects must be engaged in such specific sports during the test period. 3.2.4 The subjects and the department requiring the test must establish a close cooperative relationship. In order to ensure that the entire wearing test obtains the correct effect, a good and reasonable wearing regulation is established. Note 1: If the results need to be accelerated, it is possible to select a known hard-working wearer or a special harsh environment, but it must be related to the known normal wear. Note 2: During the entire test, it is required to wear special socks. Considering that the color of the shoes is stained on the socks, it is required to wear white socks. The score rate in 4.2 is used to evaluate the degree of contamination of the socks during wearing. 3.3 Test steps
Shoe pairing must be carried out according to the following items: 3.3.1 Each pair of shoes consists of a new shoe and a controlled shoe, which are worn by each subject at the same time. In order to offset the deviation caused by wearing all left feet or all right feet, half of the subjects wear the controlled shoe on the left foot and the other half wear the controlled shoe on the right foot. 3.3.2 Under the condition that the color, style and other aspects do not change, it is not allowed to proceed according to 3.3.1. Each subject shall wear a pair of new shoes and a pair of controlled shoes continuously under the same conditions and time. The number of pairs of controlled shoes and new shoes worn at any time during the test shall be equal. Moreover, any factors that may affect the test, such as climatic conditions, shall be minimized during the test. 3.3.3 Left/right differential offset is best to adopt 3.3.1; if 3.3.1 and 3.3.2 are combined, two pairs of shoes shall be provided for each subject, one pair of new shoes and one pair of controlled shoes, and the continuous wear described in 3.3.2 shall be performed, but the composition of each pair of shoes is as described in 3.3.1, one pair of new shoes and one pair of controlled shoes. 3.4 The types and durations of wear tests for footwear are shown in Table 1, and the format of wear test report is shown in Table 2.

Judgment of design and structure defects/wearing suitability 3.5 At least 3/4 of the changes in the load category should be obtained from the test. For the evaluation of the test shoes, at least three judges should make an impartial judgment according to 4.2.
3 It will be more helpful if the subjects record the time interval during the test. 3. ? At least 2/3 of the test wall, according to 10%, 20%, 50%, 100% of the time interval to identify its suitability, and in each stage to record the common defects,
Note 3: There is no time design, the results are not affected, then briefly check the first two items of the test (ie 10%, 20% stage) 3. If you want to allow the test period to be replaced before the test period, in order to allow the other aspects of the shoe to be evaluated, the replacement part should be able to: super heat and continuous mechanical performance. 3! Welcome to the realization of the system, the new test results are expressed
HG /T2878—1997
. 1 Mark the most measurable objective evaluation of each change relative to the controlled shoe on each pair of shoes as much as possible, and take the arithmetic mean. 4.2
When the evaluation according to 4.1 cannot be carried out, compare with the controlled shoe and make a subjective evaluation of each pair of shoes on a 5-point scale, as shown in Table 3. Table 3 Subjective evaluation table
Evaluation conclusion
Much better than the controlled shoe
Better than the controlled shoe
Equivalent to the controlled shoe
Worse than the controlled shoe
Much worse than the controlled shoe
These evaluations are expressed as arithmetic means, and a comprehensive calculation can be made for each change in the controlled shoe. 5 Test report
5.1 All information shall be recorded in the format shown in Table 2. All defects must be recorded and the reasons for corrections must be stated according to Table 2\Notes\ (see 3.9).
5.2 Indicate which method in 3.3 the test was carried out. 5.3 Total number of pairs of shoes in the test and the number of each variation. 5.4 Approximate duration of the test,
5.5 Wear test results as indicated in 4.1 and 4.2
