Time in a blink of an eye to June 19th, on this day, five experts from the Ministry of Electronics Industry in Beijing have taken a plane to Guangzhou, and after entering the Shenzhen port, they were directly received to the municipal government guest house.

More than a week ago, a notice on the holding of a tape recorder quality appraisal in Shenzhen was sent to 31 electronic enterprises that produce tape recorders in the city, and it has attracted great attention.

There are many tape recorder brands in the 80s, and all kinds of well-known brands in the country have their own, such as Shanghai's red lantern brand, Yancheng's Yanwu brand, Nanjing's panda brand, Wuxi's plum blossom brand, Changzhou's star brand, Dalian's Fu brand, as well as Beijing's peony brand and Suzhou's peacock brand, etc., there are many categories, but the overall technology is relatively backward compared with foreign countries, and by the mid-80s, most of the domestic tape recorder brands are in a state of oversupply, and the backlog of goods is serious.

Shenzhen also has a lot of provinces across the country to set up branches, in addition to some well-known brands, there are many small factories to produce miscellaneous tape recorders, although the quality is very poor, but better than cheap, but also have their own sales channels.

But in any case, the Shenzhen Municipal Government held a tape recorder quality competition, for them these small factories is a very important opportunity, everyone wants to take advantage of this evaluation for their own manufacturers to win a good ranking, which will help future publicity and sales.

Therefore, after learning that the experts from the Ministry of Electronics Industry in Beijing had come to Shenzhen, some public relations personnel of some electronics manufacturers wanted to meet with these experts, but they were stopped by the staff of the municipal government and did not give them such an opportunity.

Mayor Liang Xiang still attaches great importance to the city's tape recorder quality evaluation, in order to ensure the credibility of the evaluation, he has arranged personnel to properly arrange these Beijing experts early in the morning, and refused to meet with local manufacturers, to avoid some private transactions, undermining the fairness of the award.

That evening, Mayor Liang Xiang and these experts from Beijing's Ministry of Electronics Industry had a meal in the canteen of the guest house, during which they repeatedly stressed that the competition must be fair and just, and he obviously did not want any negative news to appear in this selection competition.

Early in the morning of the second day, several experts came to the scene of the Shenzhen Tape Recorder Quality Contest under the leadership of the staff, and the reporters of Shenzhen Radio and Television Station and Shenzhen Newspaper, who received the notice early in the morning, had already appeared at the venue, waiting for the start of the competition.

The venue of this competition is located in the auditorium of Shenzhen, at this time on the stage of the auditorium, the staff has placed three rows of long tables, and the table is neatly placed on the table more than 110 kinds of tape recorder products produced by more than 30 local manufacturers in Shenzhen, which are arranged by the Shenzhen Municipal Government to purchase special personnel in the market, in order to ensure the fairness of the competition.

In addition, more than 70 reporters from radio stations, television stations and newspapers under the booth brought cameras, and the cameras were ready to shoot and record the evaluation process of the scene, and the entire selection process of the competition was semi-public, and Shenzhen and Guangzhou TV stations will record the competition into a special program and broadcast it on TV.

More than 100 tape recorders were neatly placed on the stage, which was very spectacular, and more than 10 staff members also installed various instruments and circuits, waiting for the official start of the competition.

"Comrades reporters from the media, today by our Shenzhen Municipal Government and the Ministry of Electronics Industry jointly sponsored by the Shenzhen Municipal Government and the Ministry of Electronics Industry in Shenzhen City recorder product quality selection activities officially began, I hope that through such activities, we can promote the vigorous development of our Shenzhen electronics industry......"

At this time, Mayor Liang Xiang has come to the forefront, and after he made an impassioned opening remarks, the Shenzhen Tape Recorder Quality Contest officially kicked off. Android

"Hello journalists, I would like to introduce to you the experimental projects of this competition. At this time, an expert from the Ministry of Electronics Industry who led the team picked up the microphone and introduced to the audience after Mayor Liang Xiang finished his speech: "This year's evaluation experiment is divided into 8 items, namely unpacking inspection, room temperature electroacoustic performance measurement, safety test, interference effect measurement, environmental experiment, high temperature compliance reliability test, appearance structure, process evaluation and use performance evaluation......"

It was the first time that these experts from the Ministry of Electronics Industry had evaluated the products on such a public occasion, and they were a little nervous in the face of the many media reporters present.

But when the competition officially entered the judging process, these experts from Beijing immediately entered the working state.

The first item to be evaluated was the safety of the tape recorder.

The safety of household appliances is always put in the first place, there is no doubt about this, after all, this is related to the safety of users' personal and property, so foreign countries have long formulated electrical safety laws, and domestic ones are also brewing.

A total of 6 safety experiments in this evaluation, namely marking, anti-shock insulation requirements under normal working conditions, mechanical strength, power cord and installation safety and isolation of power transformers, all projects are carried out in accordance with the relevant provisions of the safety standard SJ2484-84 of the Ministry of Electronics Industry, and the skeleton and coil fire test of power transformer also have relevant regulations.

Due to the large number of products participating in the selection and the complexity of the selected projects, the whole selection process is very time-consuming.

The safety test lasted for a whole morning, and most of the time was very boring, so that some reporters on the scene began to fall asleep, and some simply sat in the back row and fell asleep quietly.

When it was close to noon, the results of the safety test came out, and 69 of the 110 tape recorder varieties participating in the evaluation all met the requirements of 6 safety standards, standing at more than half of the total number of products, and there were 20 models of products only slightly defective in safety marks, and were also judged to be safe, so that more than 85% of the products were safety qualified products.

Almost all of the products with unqualified safety are the products of private electronics factories, and the production technology of these miscellaneous tape recorders is backward, and in order to seize the market and compress the product cost as much as possible, so there are great safety problems in the products.

"The manufacturers of these substandard products must be rectified, otherwise this kind of product will definitely cause great safety hazards if it is put on the market. When it was time for the lunch break, Wang Junmin, an expert from the Ministry of Electronics Industry in Lingtou, said to Mayor Liang Xiang.

"Well, thank you, experts. Mayor Liang Xiang nodded in response, and turned his head to let his assistant write down the manufacturers of those substandard products.

The cruelty of the competition evaluation has finally been reflected at this moment, these safety products have basically been eliminated, even if the quality of other aspects is good, there is no chance of winning.

Moreover, this competition will be publicized and broadcast on radio and television stations, and for these tape recorder electronics factories, which have a small output, their sales will definitely be worse, and even face the danger of bankruptcy and closure......
