With the development of science and technology and the growth of consumer demand, the market scale of electrical and electronic products has expanded rapidly, featuring richer‑variety products and more diverse application scenarios. Quality control has become the core of the industry’s sustainable development and attracted high attention from all parties. It is not only related to consumer safety, but also affects corporate competitiveness and industrial technological upgrading.
At present, safety, electromagnetic compatibility, reliability and energy efficiency constitute the "hard standards" for the quality of electrical and electronic products. Safety serves as the bottom line and covers multiple aspects such as electric‑shock prevention; electromagnetic compatibility ensures that products can "coexist harmoniously" in electromagnetic environments; reliability concerns product durability and stability to adapt to various scenarios; energy efficiency complies with the low‑carbon trend and drives technological innovation.
Rather than being isolated requirements, these standards run through the full‑life‑cycle of almost all categories of electrical and electronic products. Quality control over every link, ranging from raw materials, components and functional modules to finished products, is critical for products to achieve market access and win user trust.
Electrical and electronic products are a general term for equipment that takes electronic components as the core and adopts electrical‑control technology to realize electric‑energy conversion, signal processing or specific functions. Widely used in household, industrial, medical and other fields, they are fundamental facilities of modern society.
Core Components:
Electronic Part: Composed of components such as transistors, integrated circuits (ICs), capacitors and resistors, it is responsible for signal acquisition, processing and control, for example, mobile‑phone chips and air‑conditioner control mainboards.
Electrical Part: Composed of parts including motors, transformers and relays, it undertakes electric‑energy transmission, conversion and execution, such as washing‑machine motors and rice‑cooker heating plates.
Main Classifications:
Consumer‑use Products: Frequently used in daily life and focused on convenience and practicality, including household appliances (refrigerators, air conditioners, washing machines, etc.) and portable electronic products (mobile phones, tablets, earphones, etc.).
Industrial‑use Products: Designed for production‑site scenarios with emphasis on stability, durability and precise control, such as PLCs (Programmable Logic Controllers), frequency converters and circuit breakers.
Special‑purpose Products: Developed for specific fields, including medical electronics (electrocardiograph machines, ventilators), communications electronics (routers, base‑station equipment) and automotive electronics (vehicle‑mounted navigation systems, engine controllers).
Core Characteristics:
High‑level Electronization: Intelligent control realized by integrated circuits and microprocessors, e.g. precise temperature control of inverter air conditioners and reservation functions of smart rice cookers.
Electric‑energy Driven: Most products are powered by power grids or batteries to achieve energy conversion (electric energy converted into mechanical energy, thermal energy, etc.).
Function Integration: Modern products tend to integrate multiple functions; for instance, smart‑TVs combine audio‑video playback, internet access, screen‑casting and other capabilities.
