Akron Abrasion Tester – Determination of Abrasion Resistance of Vulcanized Rubber
Request for Quotations Definition and Meaning The wear resistance of vulcanized rubber is expressed with the abrasion loss of the rubber sample under mechanical friction. This method is called the Akron abrasion method. Usually, the sample is mounted into an Akron Abrasion Tester. The [...]
Guide on the UN38.3 Test
When it comes to“UN38.3”, most people feel strange with this noun because they have little chance to hear it. UN/DOT 38.3 is familiar to the manufacturers of lithium batteries and electronic products, shipping agents, airlines staff, customs officers, etc., because people in these [...]
How to Determine the Leather Tensile Strength
Tensile strength refers to the tensile force on the unit cross section of the broken part of the sample when the sample of the finished leather is pulled to break at a certain rate, expressed in MPa. The purpose of measuring the tensile strength of [...]
How to Perform Leather Abrasion Resistance Test
Among the most watched properties of leather, abrasion resistance is one of them, because leather’s ability to withstand abrasion is directly related to the quality level and working life of leather. For instance, the common leather products we can touch in our daily life include [...]
How to Conduct Water Penetration Test for Leather on Flexing
It is normal that Leather shoes encounter water when worn, so determination of water resistance of leather subjected to flexing is necessary for product developers and manufacturers. Leather dynamic water penetration tester is used to let the grain surface of test leather in continuously flexed [...]
How to Test Water Vapour Permeability(WVP) of Leather Using Dynamic Method
Water vapour permeability of leather means the ability that the water vapour comes into the air whose humidity is lower than leather from the air whose humidity is higher through the leather or fur. Because leather has water vapour permeability, it can help wearers in [...]
How to Use Ball Burst Method to Measure Uppers Resistance to Damage(Distention and Strength of Leather Surface)
Leather of upper stretched tightly on the last or worn on the feet is not only subjected to tensile force from different directions, but also subjected to jacking force of vertical direction, so conducting the bursting strength test as a practical and comprehensive index is [...]
How to Measure the Thickness of Leather with Leather Thickness Tester
Different types of leather have different requirements for thickness. For example, the thickness of general cowhide leather for vamp is 1.2mm-1.5mm, and sheepskin leather for upper is 0.6mm-0.9mm. Determining the leather thickness is also an indispensable step before making determinations of leather tensile strength, leather [...]
