FDA, SGS, MSDS, UL and property list. What do they stand for?

1. FDA is the abbreviation of Food and Drug Administration (Food and Drug Administration), in China, because of its higher standards, so more to the U.S. FDA as the highest norms, therefore, FDA sometimes also stands for the U.S. FDA, in fact, China also has FDA. Therefore, FDA sometimes also stands for the U.S. FDA, in fact, China also has FDA. FDA as a scientific regulatory agency, the FDA's responsibility is to ensure the safety of food, cosmetics, drugs, biological agents, medical devices and radiological products produced or imported into the U.S. The FDA is one of the first organizations to focus on consumer protection, and it is one of the first organizations to focus on consumer protection. It was one of the first federal agencies to have consumer protection as its primary function. The agency is relevant to the lives of every U.S. citizen. Internationally, the FDA is recognized as one of the largest food and drug regulatory agencies in the world. Many other countries seek and receive help from the FDA to promote and monitor the safety of their own products.

2. SGS stands for Societe Generale de Surveillance S.A., which translates to "General Notary". Its headquarter is in Geneva, Switzerland, and its branch in China is called "SGS Technical Services Co.

SGS, founded in 1878, is the world's largest and oldest civil third-party multinational company engaged in product quality control and technical appraisal. Headquartered in Geneva, Switzerland, SGS has more than 1,250 branches and specialized laboratories around the world and more than 64,000 employees (including researchers, engineers, Ph.D.'s, chemists, auditors, inspectors, etc.) who carry out inspections, accreditations, tests and certifications in 143 countries around the world.

SGS's service capabilities cover the upstream and downstream of the supply chain in a wide range of industries, including agriculture, minerals, petrochemicals, industrial, consumer goods, automotive, and life sciences. In recent years, we have continued to innovate and forge ahead in the fields of environment, new energy, energy efficiency and low carbon. We are committed to promoting the harmonious ****winning of the economy, the environment and the society with our professional testing and certification services, and to providing comprehensive sustainable development solutions for global enterprises, governments and organizations.

3. MSDS (Material Safety Data Sheet) that is, chemical safety instructions, can also be translated as chemical safety technical instructions or chemical safety data sheets. It is a document used by chemical manufacturers and importers to clarify the physical and chemical properties of chemicals (such as PH value, flash point, flammability, reactivity, etc.) as well as the possible hazards to the user's health (e.g., carcinogenicity, teratogenicity, etc.).

4. UL is the United States Underwriters Laboratories (Underwriter Laboratories Inc.) abbreviation. UL Safety Testing Institute is the most authoritative in the United States, but also in the world engaged in safety testing and identification of the larger civil institutions. It is an independent, non-profit, for the public **** safety test professional organizations. It uses scientific testing methods to determine a variety of materials, devices, products, equipment, buildings, etc. on life, property and the degree of harm; to determine, write, issue the corresponding standards and help reduce and prevent the loss of life and property caused by the information, while carrying out fact-finding operations.

5. Physical properties table

Physical properties of one

Physical properties of substances such as: color, odor, state, whether easy to sublimate, volatile, etc., can be used to people's ears, nose, tongue, body and other senses, but also some of the properties, such as melting point, boiling point, hardness, electrical conductivity, thermal conductivity, ductility, etc., you can use the instrumentation to know. There are also some properties, through the laboratory to obtain data, calculations, such as solubility, density, corrosion resistance. The substance remains unchanged before and after the experiment. All these properties are physical properties.

Edit the physical properties of the second

Usually use the observation method and measurement method to study the physical properties of substances, such as can observe the color of the substance, the state, melting point and solubility; you can smell the smell (most of the medicines in the laboratory is toxic, without the permission of the teacher must not use the nose smell and mouth to taste); you can also use the instrument to measure the substance's melting point, boiling point, density, hardness, electrical conductivity, Thermal conductivity, ductility, etc.
