In our daily life, no matter what shoes you are worn, what type of floor is walking. The sudden slip accident would occur often which would cause the injury to people.With recent technological developments, footwear manufacturers are constantly introducing new types of sole materials. The anti-slip index of the shoes is a very important data, which may determine whether the shoes could win the good graces in the international market. At present, footwear slip data is obtained through institutions that meet international standards. BS EN 13287 and SATRA TM144 are the most authoritative standards. Both standards provide a detailed and rigorous description of the test methods and test materials, including: the various materials used as the floor, the way the shoes are in direct contact with the floor (only the forefoot touches the surface to be tested, only the heel contacts the surface to be tested) And the entire sole is in contact with the surface to be tested), the test procedure and the method of obtaining the data (normal force, friction, friction coefficient). GESTER has been committed to the development and production of various types of test instruments in line with international standards. At present, our company has launched the footwear slip resistance tester GT-KB48 for footwear anti-slip test. This machine complies with BS EN 13287 and TM144.Let's take a look of the difference during testing between BS EN 13287 and SATRA TM 144. BS EN 13287 Test Procedure: Step 1)  Firmly install the shoes on the shoe lasts or mechanical feet. Be careful not to have any slippage or looseness; if so, it’s necessary to take anti-slip measures (such as: playing paper towels in the shoes or double-sided tape on the bottom of the mechanical foot) . Apply a suitable lubricant to the shoe, uniform thickness, about 1mm thick, and place the floor material to be tested on the motion test platform. Step 2)  Lower the fixed shoe to the surface to be tested so that the shoe is in contact with the test surface. There are three ways of contact (only the forefoot contact surface, only the rear heel contact surface, and the full sole contact surface). The forefoot contact and the rear heel contact require a 7 degree angle block to allow the shoe to contact the surface at an angle of 7 degrees. The three methods must ensure that the relative movement direction of the shoe and the test surface are opposite and parallel. In order to simulate the scenes in life. Step 3)  After the shoe contacts the surface, apply a pre-plus normal force (50N) in a vertical downward direction, reach a normal force of 500N in 1s and prepare to slide the test platform. The force at this time is called static contact force and arrives. Sliding started within 0.3S after 500N, and the sliding speed during the test was 0.3 m/s. Step 4)  The data between 0.3s and 0.6s after the start of sliding is the measurement interval of the average frictional force, and the length of the m...

GESTER GT-KC10A Bally Resistance Flexing Tester has A, B two types grips, and the difference lies in the upper grips. A Type grip is complied with below standard: SATRA TM 55;IULTCS/IUP 20-1; ISO  17694 ; EN 13512 ;EN 344-1 section 5.13.1.3 and annex C;EN ISO 20344 section 6.6.2.8;GB/T20991 section 6.6.2.8;AS/NZS 2210.2 section 6.6.2.8;JIS-K6545. Bally Leather Flexing Tester B Type grip is complied with below standard: ISO 32100 ; DIN53351; ISO 5402-1;GE-24;ASTM D 6182. Since the two clamps are suitable for many standards, the same basic dimensions and different tolerances are taken with smaller tolerances, which are regarded as the same standard. The main difference between two grips is as below: As figures showed, fig.1 for A Type Upper Grip,fig 2 for B Type Upper Grip Both upper clamps consist of two plates, one for ABCFD and one for EGHCF. The main differences between the two upper clamps are: 1.The thickness for A type baffle  ADFE is 4mm. While the thickness for B type grips baffle ABCFD, EGHCF is 4±0.2mm, and baffle L(ADFE) can be added to 8mm regarding the test sample. 2.The horizontal length and vertical height for A type upper clamp ramp CD are both 25mm ( D is the intersection for CF and AD extension). The horizontal height difference between the B type upper clamp surface BC and EF is 22.5±1 mm, and the horizontal distance from the hole core to the acute angle angle F is 23.2±0.2 mm, and the diameter of the hole K is required to be ∮50.0±0.5 mm. 3. The angle between the DF and CF of the A type upper clamp is a radius of 2 mm. B type upper clamp DF is: a plane that is 150 degrees obliquely upward (∠ADF=150°) with the lower surface AD. The plane DF and the inclined plane CF are arcs with a radius of 2 mm.

The necessity of rubber flame retardant With the continuous advancement of technology, rubber products have been widely used in various industries. Wire and cable, rubber rope, conveyor belt, rubber hose, air duct, rubber belt, and rubber products used in the electrical and electronic industry must meet the corresponding national standards in terms of flame retardancy and mechanical properties. The requirements for flame retardant properties of rubber products are also increasing, and the development and application of flame retardant rubber has become particularly important. There are many types of rubber, and various rubbers have different combustion properties. Most of the rubbers have a low oxygen index and a low decomposition temperature, which is easy to burn. Therefore, it has become the main way to prepare flame retardant rubber by researching on rubber burning characteristics, adding flame retardant or improving the burning performance of rubber itself. Several important ways of rubber flame retardant The main way of flame retardant is to slow down the thermal decomposition and block the combustion process. The specific flame retardant routes are as follows: The addition of one or more substances changes the thermal decomposition behavior of the rubber, so that the prepared rubber has a high thermal decomposition temperature and reduces the flammable gas generated by the decomposition. The added substance can generate a non-combustible gas when heated, or produce a viscous substance that is isolated from O2, or can absorb heat when heated, so that the three elements of combustion (combustible, oxygen, reach the ignition point) cannot be satisfied. Add substances that can capture HO·, interrupt the chain reaction, and terminate the flame propagation. Change the structure or properties of the rubber molecular chain, improve the thermal decomposition ability or make itself has flame retardant. Due to the good compatibility between rubber and various additives, the addition of various flame retardants is still an important means of flame retardant modification of rubber.

Balance is a commonly used equipment in laboratory. How to use balance correctly has an important influence on the accuracy of experimental data. As the precise instruments, if we can operate and maintain it well, then will keep the live of balance. Instrodction 01 Relative terms Peeling device: device that sets the indication value to zero when there is load on the flat scale on the same day. Multi-scale: there is only one scale range, divided into several local scale ranges according to different actual scale values.The local weighing range is automatically determined according to the increase or decrease of the loaded load. For example, the scale range of a certain balance is 0-420g, the weighing range is 0-200g, the actual dividing value of the balance is 0.0001g, and the weighing range is 200-420g, the actual dividing value of the balance is 0.001g. Maximum weighing: the maximum weighing capacity when tare is added is not included. Minimum weighing: when the load is less than that, the weighing result may produce too large relative error. Actual dividing value (d) : refers to the difference between two adjacent indicating values. Calibration scale value (e) : the value in units of mass used for grading the balance and metrological verification. Test score (n) : the ratio of the maximum weight to the test score. 02 scale grade The balance is divided into four grades according to the verified degree value e and the verified degree n. Meanwhile, the accuracy level of the balance also meets the corresponding relationship with e and n, as shown in table 1. Table 1 relationship between balance accuracy level and e and n Note: in the last column of the above table, except for the special accuracy grade balance with e < 1mg, d is used to calculate the minimum weight in place of e. 03 Balance error Different scales have different maximum allowable errors (MPE), and the same scale has different maximum allowable errors in different scales. The relationship between the maximum allowable error and the scale level and weighing range is shown in table 2. Table 2 relationship between the maximum allowable error and balance level and weighing range. Use of balance Application notice： 1. Observe the level device of the balance and check whether the balance is level. Balance of balance can be adjusted by adjusting the foot bolt of balance. 2. After power failure for a long time, start the machine for preheating for 30min. If no power failure occurs, start the machine directly for use. 3. Open the windproof cover of the balance, put it into the weighing paper, and after the indication is stable, press the "clear zero" button to close the windproof cover, and observe whether the indication of the balance is zero. If not, press the "clear zero" button until the indication is zero. 4. Open the windproof cover, put the articles to be weighed on the balance, close the windproof cover, and read the indicator number after the indicator number of the balance is sta...
