Textile and clothing
Textile and clothing
With the continuous improvement of people's living standards, the needs of consumers are constantly changing. People no longer only meet the needs of food and clothing, but are more and more demanding for the quality and safety of goods. Therefore, quality testing of textiles and clothing is carried out. especially important. In addition to the current economic globalization, the products of various industries are exported to the world, and the textile industry must also be included. Quality control can be said to be indispensable. Through inspection, manufacturers can clearly judge the quality of products, and Continuous improvement based on the weaknesses of its quality inspection report can better ensure product quality. The physical performance indicators of textiles and clothing mainly include: color fastness, abrasion resistance, pilling, tear resistance, tensile strength, fabric softness, air permeability, flame retardancy, water content, thickness, etc. Having your own laboratory can improve the market competitiveness of enterprises/units, as well as better control of product quality (improving customer confidence).

Paper
Paper
Currently, worldwide, there are many types of paper and cardboard, and the number of applications is increasing. But for a certain paper or cardboard, the required physical properties vary with its use. The main physical performance indicators of paper products are: quantitative unit gram weight; whiteness; smoothness; bursting strength; tearing force; stiffness; folding resistance; tensile index; water absorption thickness expansion rate; water absorption; air permeability; Heat sensitivity; combustion characteristics; ash content; ph value, tensile strength, bursting strength, compressive strength, etc.
Paper testing equipment: PFI refiner, sheet former (sheet maker), Valley Beater, sample press, laboratory digester, Paul sieve, fiber dissociator, flat plate type Paper sample quick dryer, Canadian standard freeness meter, beating degree tester, centrifugal dryer, etc.
Toilet paper testing equipment: Nursing care products testing, diaper diaper testing, etc. According to relevant testing standards, various quality and performance indicators of various paper products such as paper, cardboard and carton are tested, including quantitative, whiteness, softness, holes, dustiness, tensile strength, transverse liquid absorption height, pH, leak performance, microorganisms, etc.

Toys
Toys
In developed countries, the protection of children is attached great importance, and the testing of children's toys is particularly strict. Children's toys generally have higher requirements in terms of physical and mechanical properties, flammability, and chemical safety, such as the suffocation hazard of small parts and the danger of pinching and stabbing. Therefore, children's toys must be strictly tested before leaving the factory, and they can only leave the factory after passing the test. The physical performance indicators of toys mainly include: flame retardant test, drop resistance test, small parts test, sharp edge test, sharp point test, tension test, pressure test, torsion test, etc. Chemicals: formaldehyde content test, PH value test, heavy metal test, etc.
Shoe Material
Shoe Material
In most developed countries, footwear inspection has been quite developed, and many important standards have been formulated, which play a key role in guiding footwear inspection. Since footwear inspection is the key to ensuring the quality of shoes, footwear inspection has gradually become the mainstream of the footwear market. The physical performance indicators of shoe materials mainly include: color fastness to rubbing, color fastness to perspiration, Martindale abrasion resistance, peel strength, slip resistance, twisting, tearing, etc.

Environment Class
Environment Class
With the development of science and technology and the pursuit of quality, more and more industries need to conduct reliability tests on products in specific environments. Since the product is constantly subjected to the influence of its own and the external climatic environment and mechanical environment during the design and application process, it needs to be able to work normally, which requires testing equipment to verify it. The main environmental testing items are: constant temperature and humidity test, thermal shock test, high and low temperature test, aging test, rain test, dust test, etc.

Electronic Appliances
Electronic Appliances
In recent years, the global economy has continued to operate at a low speed, while the laws and regulations established by various countries for the safety and other characteristics of electrical and electronic products and their corresponding enforcement have become increasingly strict. the subject.
Electronic products mainly test the performance, reliability, safety and adaptability of products.
1. Performance refers to the technical characteristics of a product to meet the purpose of use, including product performance, mechanical properties, physical and chemical properties, and appearance requirements.
2. Reliability. Reliability refers to the performance of the product to complete the task within the specified time and under the specified conditions, including the average life of the product, the failure rate, the average maintenance time interval, etc.
3. Security. Safety refers to the degree to which a product is safe during operation and use.
4. Adaptability. Adaptability refers to the adaptability of the product to natural environment conditions, such as the response to temperature, humidity, pH, etc.
