ASTM D429-73 -Standard Testing Instruments
ASTM D429-73 is an extensively used standard for testing the adhesion strength of a rubber product to a rigid substrate. This standard is divided in to eight different types from method A to method H.
Method A- In this methods, the rubber sample is places between two metal plates held parallel to each other.
Method B- This method is also called 900 stripping test- In this method, the sample is placed on a single metal plate.
Method C- In this method the adhesion of the sample is measured with a narrow pointed specimen on the metal plate.
Method D- This is used for explaining Bonding of rubber and metal post vulcanization.
Method E- This is used for testing the adhesion of rubber tank lining that is placed on a single metal plate.
Method F- This method involves two convex metal surfaces held parallel with the rubber coating placed on them.
Method G- This method is used for determining the bond durability of dual shear cylindrical specimen with rubber-metal bonded components.
Method H- This method is used for testing the bond durability of rubber metal components in a quadruple shear specimen.
Tensile Testing Machine Digital
It is highly recommended for evaluating the tensile strength of products and materials. The equipment is based on the Constant Rate of Traverse (CRT) principle. It is equipped with an upper jaw and a lower jaw. Universal Tensile Testing Machine is a reliable piece of equipment which is widely used for checking tensile strength of a product/sample. One of the most common mechanical testing techniques used to determine tensile strength, this is a method wherein controlled tension is applied to a sample until it fully fails.
Thus, the material properties of the sample can be easily determined by this test. It involves measuring the force required to elongate a sample under test to breaking point. Using this test, manufacturers and quality managers are able to determine the core strength of their products.

UTM Machine – zeus ultimo 3
Presto Stantest Universal Testing Machine (UTM) is a load-testing instrument that pulls or pushes a sample to measure its strength. The word "universal" is there for a reason — the same machine handles tension, compression, bending, peeling and shear, depending on the grip and fixture you fit to it.
Most people use it for tensile tests, where a specimen is gripped at both ends and slowly pulled apart. The force needed to break the sample tells you its strength, and the amount it stretches before breaking tells you about its flexibility. That is why the equipment is also known as a Universal Tensile Tester or a Universal tensile strength tester — the tensile test is its most common job.
In short, if you want one honest answer to "how strong is this material?", a tensile testing machine of this kind is the tool that gives it.
