On April 2019, the European Committee for Standardization (CEN) published a new version of European standard EN 71-3:2019, Safety of toys - Part 3: Migration of certain elements. This standard will be given the status of a national standard and the conflicting national standards will be withdrawn by October 31, 2019 at the latest. The current harmonized standard for the migration of specific elements of the EU Toy Safety Directive is EN 71-3:2013+A3:2018. But EN 71-3:2019 is expected to be harmonized under the Toys Safety Directive (2009/48/EC) when accepted by the European Commission (EC) and published in the Official Journal of the European Union (OJEU).

According to the statistics of World Health Organization (WHO), flame burns are the 11th cause of death and 12th cause of disease in children aged 5-14 years worldwide. And, the textiles with flame retardant function has become the focus of attention. So what is the flame retardant properties of textiles? Material burning performance The "flame retardancy" does not mean that the textile after flame retardant finishing will not burn when it contacts the source, but for the fabric can reduce its flammability as much as possible in the fire, slow down the spread speed, and does not form large-area combustion. And after leaving the flame, it can quickly extinguish itself, no longer burning or smoldering. Those protective fabrics that prevent themselves from being ignited or that slow down and terminate combustion after exposure to flames or hot objects are flame retardant fabrics. Classes of flame retardancy of fabrics (1) fiber flame retardant: direct production of flame retardant fiber or flame retardant fiber with high temperature fabric, with permanent flame retardant; (2) post-finishing flame retardant: chemical modification or fire-retardant post-finishing of textiles has a low cost, but the flame retardant generally decreases or disappears with the increase of service life and washing times. Test method for flame retardancy of fabrics The flame retardant test method of the fabric is different according to different conditions. Common test methods are: vertical combustion method, 45°combustion method, horizontal combustion method, limit oxygen index method, etc. Fabric flame retardant tester: 45 Degree Automatic Flammability Tester GT-C32 Horizontal Flammability Tester GT-C34A Horizontal Flame Chamber GT-C34B Vertical Flammability Chamber GT-C35

GESTER Instruments introduces some little common sense about shoes. 1. How to distinguish the quality of outsole? There are various outsole material for leather shoes, such as polyurethane, modified polyvinyl chloride etc. The property of flex resistance, abrasion resistance and hardness of outsole are all specified in national industry standard. When choosing the shoes, the outsole should be with elasticity when pressed. And check if any  small piece falling off from the bottom when pulling it. Also, it shouldn’t be sticky when touching, should be soft when bending. The quality failure in outsole is a common phenomenon nowadays, the cracking and massive falling off happen occasionally. The reason why it occurs is coming from the sole manufacturer, pursuing more profits and regardless of the quality, which makes the quality failure. GESTER owns below testers for the performance of that: Shoes Flexing Tester GT-KA01-3, EN Sole Flexing Tester GT-KB06. 2.How to distinguish the quality of steel shanks? What is the function for it? Each leather shoes exists one piece of steel shanks, except flats and wedges. It is installed between the outsole and the midsole of the sole and It is the backbone of the shoe, which maintains the bottom curvature and stabilizes the heel. The standard requires the performance of Longitudinal bending stiffness and hardness. When picking shoes, you can use your hand to press the foot part of the shoe moderately, the best condition is that is will not becoming soft or deformed.  After wearing, if you find that the heel is skewed or feeling uncomfortable, you can check whether the hook is broken or not. The application: Steel Shanks Stiffness Tester GT-KB46 3. Why leather shoes are always with low glue-intensity? It’s very common that adhesive leather uppers and bottoms are not firmly bonded. There are many reasons for unglued, mainly due to the selection of raw materials in the factory and improper control of the process. The rubber sole and the leather can be glued with neoprene, and the imitation leather bottom and the polyurethane bottom with more resin components are difficult to be effective, and it is necessary to use a polyurethane finger glue or other adhesive to adhere. Because an adhesive is not suitable for any material. Before the bonding, the sole and the upper should be ground and raised, multi-passed and baked, and pressed with a press to bond. The adhesion to the shoes is the peel strength. The adhesion of leather shoes is controlled by the peel strength index, which is measured by GT-KC41 Shoe Peeling Strength Tester. 4. Is it reliable to use cardboard as insole ? In the past, the insole of leather shoes was made from pig and cow bottom leather. Natural leather resources are now reduced. Substitute materials are used to replace certain natural materials. Insole cardboard for shoes is widely used at home and abroad. The shoe insole with good quality have hygroscopicity, gas permeability, flexing...

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.
