The oxygen index is the minimum oxygen concentration required to maintain a smooth combustion of a specimen in a mixture of oxygen and nitrogen in a specified strip. It is expressed as a percentage of the volume of oxygen. The oxygen index is an important physical and chemical parameter for determining the combustion characteristics and fire risk of a substance. Due to the needs of industry testing standards, Jensen has developed both an oxygen index value for testing the combustion properties of solids and an oxygen index value for determining the combustion of liquids. http://burningtester.com/news/590.html Instrument construction.

The preparation and operating procedures before using the Taber Abrasion Tester are as follows. 1. Secure the specimen on the test turntable, attach the required test weights and ensure that the test wheel does not come into contact with the specimen's secure fixture during the test. 2. After setting the number of tests according to the test requirements, the whole machine is in standby mode. Operation example: Zhang 1. Connect to the appropriate power supply 220V or 110V according to the label 2. Manually rotate the test disc to ensure that the grinding wheel does not come into contact with the fixture during the test. https://www.testerinlab.com/news/703.html

On 26 January 2022, the Committee on Dumping, Subsidies and Non-Tariff Barriers to Trade of the Peruvian National Institute for the Protection of Competition and Intellectual Property issued Notice No. 007-2022/CDB-INDECOPI, initiating an anti-dumping investigation against 100% polyester fabric originating in China, upon the application of Peruvian enterprise TecnologíaTextilS.A. On 25 August 2022, Peru issued a decision in the case. On 25 August, Peru made an affirmative preliminary ruling on the case, preliminarily ruling that a provisional anti-dumping duty of US$3.93/kg was imposed on the product in question, valid for six months. https://www.qinsun-lab.com/News-and-events/2043.html

The choice of environmental temperature: some products need to be tested in a temperature environment of minus degrees Celsius ozone resistance test, some are tested at room temperature, and some are tested at high temperatures. Users just need to understand their own products to test the common test temperature can be. It is important to note that testing at room temperature is more common. Conditions can be placed in the Ozone aging chamber premises equipped with air conditioning systems, it is recommended that users choose the test chamber with a refrigeration system when purchasing, to avoid the summer test, the temperature is too high resulting in inaccurate results. Ozone aging chamber Chamber volume selection: because the Ozone aging chamber chamber materials and ozone concentration control accuracy difficulties will have a corresponding increase, so as long as the test products can be accommodated on, too large chamber will only cause waste. https://www.standard-groups.com/en/News/709.html#m

Because there is no sensor (probe) that can be put into sodium chloride (salt) for testing, according to the international standard, it is 5% sodium chloride solution, that is, the ratio of salt to water is 1:19, but we all use salt It is prepared after weighing with water. http://thentest.com/News-and-events/1746.html

Water-cooled xenon lamp aging tester Atlas xenon lamp aging test chamber Water-cooled xenon lamp aging tester through the xenon lamp tube to complete the test of products and materials and produce results, the quality of the xenon lamp tube is very important for the equipment. So we should always pay attention to this aspect of the environmental testing industry, there are many test equipment manufacturers to play the price war, these three or five manufacturers will be in order to make profits and constantly reduce the production costs of water-cooled xenon lamp aging tester, the use of inferior xenon lamp and other spare parts. The price of this water-cooled xenon lamp aging test chamber is very low, in the use of the time it is easy to fail, there may be serious safety hazards in the use of the process. Even if there are no safety hazards, the inferior xenon lamp can not play the role of aging only the role of lighting, for the test can not help, the results of the test will not be accurate. https://www.standard-groups.com/en/News/707.html#m

pay attention to for spring tension and compression testing machine: 1. The displacement sensor is a precise optical, mechanical and electrical measuring device, which cannot be disassembled or impacted at will.2. The internal memory can store the data of 40 samples at most. When the number exceeds this number, it will be automatically overwritten and stored from 1. If you need to save the function that will be overwritten, please use the "Query/Print" button in advance to save the data. This content is printed.3. If there is abnormal sound during the operation of the testing machine, stop the machine immediately and check the lubricating parts.4. After the test machine is used, it should be covered with machine clothes to prevent dust from falling into the machine.5. In order to protect personal safety, the testing machine should be properly grounded. https://www.qinsun-lab.com/News-and-events/2028.html

The Abrasion Resistance Tester is an important instrument for measuring the performance and durability of leather products in use. During the test, the abrasion resistance of the specimen is determined by applying friction in the tangential direction to a rotating specimen by means of a friction component. Fastness to Friction. It is the degree to which the colour and coating of the leather surface changes or is transferred when the leather is rubbed. Fastness to friction test with standard white lining cloth or white wool sticky, under a certain pressure (test head mass 500g, 1000g ), in the leather surface for reciprocal friction (dry white lining cloth or white wool sticky for reciprocal friction for dry friction, with wet white lining cloth or white wool sticky for reciprocal friction for wet friction), and use standard grey sample card to assess the leather colour change and white lining cloth or white wool sticky The change in colour of the leather and the staining of the white lining or white wool. leather product Test methods for determining the abrasion resistance of leather: There are two methods for determining the abrasion resistance of leather, namely the end point method and the change in appearance method.
