Information on the most widely used ASTM standards within the materials testing industry
Model: YDW-300
General Introduction
Key Features
a) The use of advanced AC servo motor speed regulation drive system, speed regulation ratio of 1:10000, according to the needs of the acceleration speed of 0.05-100mm/ min to achieve any pressure plate rise speed;
b) Full mechanical structure, from servo motor to servo reducer, the use of fully sealed structure, no need to replace the lubricating oil during use, there is no pressure oil leakage and proportional valve blockage;
c) The main engine is designed in accordance with ergonomic standards, making the operation simple, convenient and fast. Measurement control with high precision and intelligence;
d) Give full play to the advantages of the microcomputer, reduce the electronic control system hardware, and integrate all electrical parts into two modules, which greatly improves the reliability of the product;
e) Exceeding a certain range of the maximum test force (overloading 2-5% of the gear), or when the piston hits the limit, it can be stopped immediately;
f) Each measurement data can be stored permanently for later observation;
The test force and displacement measurement control are concentrated on the test interface of the microcomputer, which is intuitive and easy to operate.
The main engine of the pressure testing machine is a gantry frame composed of two columns, upper beams, a base plate and a table. The transmission mechanism is composed of AC servo motor, belt, reducer and precision screw to realize the up and down movement of the mechanical piston, so as to realize the movement of the specimen pressure plate. Complete the compression experiment. Its compact structure and smooth transmission. The mechanism ensures that the frame has sufficient stiffness while being smooth and efficient. In the process of testing, the load sensor on the upper beam determines the size of the test force, the microcomputer software controls, the compression test is automatically completed, and the data is collected and printed.
ASTM C39 "Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens“
ISO 679:2009 "Cement -- Test methods -- Determination of strength"
ISO 679:2009 specifies a method of determining the compressive and, optionally, the flexural strength of cement mortar containing one part by mass of cement, three parts by mass of ISO standard sand and one half part of water.
ISO 679:2009 applies to common cements and to other cements and materials, the standards for which call up this method.
