我. Machine Overview: This machine is designed for life-cycle testing of various switches or small finished products (buttons/keys). It features adjustable speed and cycle settings, and conducts simultaneous testing across four stations. Data is retained upon completion of the test cycle. Load application utilizes a weight-based system to ensure testing accuracy. II....
In fields such as automotive coating, industrial anti-corrosion, home appliance finishing, and wood coatings, the scratch resistance of coatings is a key indicator for measuring product durability, appearance quality, and service life. Fine scratches generated during daily use, hard abrasion during handling, and coating damage caused by environmental friction will...
In the coating, 墨水, and finishing industries, 遮盖力 (covering power) is a core indicator that determines coating appearance quality, construction cost, and color matching stability. How to horizontally compare the hiding performance of similar white and light-colored paints? How do laboratories and factories unify test criteria? All these questions...
In the quality control and international trade of apparel, home textiles, and technical textiles, there exists a fundamental standard system that runs through the entire industrial chain — ISO 105 Textiles — Tests for Colour Fastness. Developed by ISO/TC 38 (Textiles Technical Committee), it is the most widely recognized and...
Foot protection is an essential part of occupational safety systems across industrial workplaces. Molded polyurethane (PU) safety boots are widely adopted in chemical, construction, environmental sanitation, manufacturing and other general industrial sectors due to their lightweight structure, outstanding wear resistance, waterproof performance and excellent acid and alkali resistance. To unify...
In the printing, packaging and papermaking industries, paper surface strength is a core indicator that determines finished printing quality and prevents common defects such as surface picking, layer delamination and paper peeling. During printing processes, paper is subjected to dual forces of ink adhesion and mechanical tension. Insufficient surface strength...
我. Basic Standard Overview & Version Evolution 1.1 Basic Standard Information ASTM D1052 is a core fatigue bending test standard for rubber elastic materials issued by ASTM International. Full Standard Name: Standard Test Method for Rubber Deterioration—Crack Growth Using Ross Flexing Apparatus, administered by ASTM D11 Committee on Rubber and Elastic Materials. Belonging...
In the chemical industry such as plastics and coatings, the film-forming properties of polymer dispersions directly determine the quality, stability and application effect of products. As a core standard developed by the International Organization for Standardization (国际标准化组织), 国际标准化组织 2115 specifically specifies the determination methods of white point temperature and minimum...
