Shandong Consumers Association launched a "comparative test" of belts, and three brands were found to be unqualified.
In order to provide consumers with accurate consumption information, fulfill the functions entrusted by the Law on the Protection of Consumers' Rights and Interests and the Regulations on the Protection of Consumers' Rights and Interests in Shandong Province, and strengthen the social supervision of goods and services, Shandong Consumers Association and Shandong Leather Industry Association conducted a belt comparison test on June, 2065438+0 1.
? Through experiments, Sefilo in Guangzhou, CARTELO in Dongguan and A& brands; Some data of MAPE belt were found to be unqualified.
It is understood that Shandong Consumers Association will also carry out a series of comparative experiments involving a wide range of products. Most of the samples tested are big brands, and the pass rate is 85%. Qilu. Net News reporter learned from Shandong Consumers Association.
In order to ensure the reliability of this comparative test sample, the staff of Shandong Consumers Association and Shandong Leather Industry Association randomly bought 20 belts of 20 brands in Jinan Ginza Shopping Mall, He Jiong Shopping Mall, Zhenhua People's Shopping Mall, Jiahua Shopping Plaza and Golden Monkey Store as ordinary consumers. The test samples are all products from inside and outside the province, and the prices are mainly in the middle and low grades.
The results of initial inspection and re-inspection of 20 belt samples show that 17 samples meet the national standard (the inspection report is qualified) and 3 samples do not meet the national standard (the inspection report is unqualified). The qualified rate of the sample is 85%, and the unqualified items mainly focus on two indicators: bite force and rubbing color fastness.
From the comparative test list, the reporter found that the data of seat belt buckle force of CARTELO and Sefilo brand test models were 148N and 155N, respectively, which were lower than the qualified standard of 180N.
Guangzhou Apple Five Star Leather Co., Ltd. A & amp； The rubbing color fastness of MAPE brand test belt does not meet the standard, which is lower than the qualified standard, and the wet friction is less than grade 3.
Buying leather goods is a four-point trick in learning. You should remember:
1. Watch your appearance. When choosing a belt, consumers should pay attention to the smooth leather surface, uniform thickness and no defects such as peeling, cracking, pulp cracking, surface cracks, knife wounds and yarn jumping. There is no rust and burr on the buckle and riveting parts, and the coating is even and scratch-free. The belt edge is smooth and does not fade, the belt body is neat, and the accessories are smooth and burr-free.
2. Products with high selectivity. Consumers should not be greedy when buying. It is best to go to a regular shopping mall, choose an economical and practical belt with high cost performance, ask for invoices and receipts, and pay attention to preservation.
3. Pay attention to internal quality. According to the physical and chemical index data of the comparative test, the highest breaking force of the belt can reach 2067N and the lowest is 34 1N, with a difference of 6 times. The maximum bite force of the buckle is 585 N, and the minimum bite force is 148N, with a difference of nearly 4 times. The color fastness to rubbing reaches the highest level of 5 and the lowest level of 1 to 2, with a difference of nearly 4 times.
4. Pay attention to maintenance. Belt is a consumable, which will break down if used for a long time. So pay attention to the maintenance of the belt. Usually, it should be wiped with special leather care, not with detergent containing strong alkali. The belt should be kept away from chemicals and liquids to avoid being poked and scratched by sharp objects.
Friendly reminder:
What is a comparative test?
Belts of different brands with the same price have undergone various scientific experiments (mainly three items: appearance quality, sewing requirements and physical and chemical indicators), and comparative analysis has been made according to the experimental results.
Contents of this comparative test:
This comparative experiment * * * examines the appearance quality, sewing requirements and physical and chemical indicators. Appearance quality includes face material, buckle, sling, rivet, hole, belt edge, belt tail, belt bottom, belt body, belt ring and so on.
Sewing requirements include needle distance, hemming, stitches, etc. Physical and chemical indexes include rubbing color fastness (grade), belt breaking force (n), buckle bite force (n), fracture performance (n), buckle wear resistance and corrosion resistance (grade), etc.
Bite force of belt buckle: it refers to fixing the belt head and the belt on the tension machine, with the distance between the fixing points being 150 mm, starting the machine until the belt head falls off, and reading the highest value as the bite force of the belt.
Color fastness to rubbing: the surface and interior of the belt were tested according to the regulations of QB/T2537, and the quality of the test head was1000g. ..
