[temperature shock testing machine] indispensable testing equipment for LED products
June 2, 2017 source: navigation instruments Author: editor in chief
LED products are divided into LED TV, LED fluorescent lamp, LED street lamp, LED flash lamp, LED display screen, led ceiling lamp, LED lamp bead and LED energy saving lamp, These are all Has been integrated into our daily In life.
In recent years, with the rapid development of restaurants, hotels and service industries, China's LED products have witnessed a synchronous growth and become one of the fastest growing markets in the world. However, after years of catching up, some medium and high-end manufacturing enterprises have gradually narrowed the gap with the international advanced level in R & D and manufacturing level, and some technologies have even reached the world level, which is impacted by hot and cold test Box work is indispensable.
The cold and hot shock test chamber is a necessary test equipment for metal, plastic, rubber, electronic and other material industries. It is used to test the degree of material structure or composite material, which is subjected to continuous environment of extremely high temperature and extremely low temperature in an instant, so as to detect the chemical change or physical damage caused by thermal expansion and contraction in the shortest time.
The standards of cold and hot shock test chamber are as follows:
1. GB / t2423.1-2001 low temperature test method;
2、GB/T2423.2-2001;
3. GB / t2423.22-1989 temperature change test n;
National standard gjb3.4;
5. National military standard gjb150.4-86;
6. National military standard gjb150.5-86;
7. Gjb150.5-86 temperature shock test;
8. Gjb360.7-87 temperature shock test;
9. Gjb367.2-87 405 temperature impact test;
10. A series of box type test of temperature t10187-sy9187;
11. SJ / t10186-91y73 series temperature change test chamber -- two box type;
12. Meet the standard iec68-2-14_ Test method n_ Temperature change;
10. GB / T 2424.13-2002 test methods - temperature change test guidelines;
11. GB / T 2423.22-2002 temperature change;
12. QC / t17-92 general rules for weathering test of auto parts;
13. EIA 364-32 thermal shock (temperature cycling) test procedure for electrical connectors and sockets.
In the future, the scale of LED products will continue to expand, guide the rapid growth of demand, and promote the rise and development of cold and hot shock test chamber. Some manufacturers of high-end products increase technical investment, introduce advanced production equipment, constantly improve the technical performance of products, and develop new products to meet the market demand. As a result, leading technology manufacturers can obtain more profits, ensure continuous investment in R & D and equipment, and maintain a dominant position. The improvement of technology content also improves the entry threshold of the industry, avoids vicious competition in the industry, and ensures the healthy development of the industry. The speed of industrial concentration in China has accelerated.
our country LED products have fully entered the stage of market-oriented competition, each enterprise faces the market independently, but the development of high-end and low-end products in the market is not balanced.   
In view of the improvement of product quality awareness, hot and cold shock test Box as LED product testing is more and more trusted by customers. New requirements are put forward for the construction of product quality system, and higher requirements are put forward for the R & D strength, delivery period and quality assurance ability of production enterprises. Enterprises with similar scale are required to provide supporting services for them. Dongguan zhenghang instrument Owned by equipment Co., Ltd More than ten Years of production and R & D experience manufactor The direct selling method benefits customers.
