5 Apparatus5.1 Testing Machines—Machines used for tension testing shall conform to the requirements of Practices E 4. The forces used in determining tensile strength and yield strength shall be within the verified force application range of the testing machine as defined in Practices E 4.5.2 Gripping Devices:5.2.1 General—Various types of gripping devices may be used…
6 Apparatus6.1 Differential Scanning Calorimeter—As a minimum requirement, the thermal analysis equipment shall be capable of measuring heat flow of at least 10 mW full scale. The instrument recorder shall be capable of displaying heat flow or temperature differential on the y-axis and time on the x-axis. The time base must be accurate to 61…
The best method for testing electrotechnical products with regard to fire hazard is to duplicate exactly the conditions occurring in practice. In most instances this is not possible. Accordingly, for practical reasons, the testing of electrotechnical products with regard to fire hazard is best conducted by simulating as closely as possible the actual effects occurring…
System is installed on extruder input, and measures the Kg/h output of extruder continuously. Based on requested weight per meter of pipe, system knows how much should be the line speed. Along with the unit also an encoder will be installed on puller of the extrusion line to measure the real line speed. Speed control…
Ultrasonic technology for thickness measurement is using ultrasound reflection time between our surface of the pipe and inner surface. If you calibrate the device for sound speed in the target material then machine can calculate the thickness. Sound speed in different materials depends mainly on material type and temperature. Of course when you calibrate device…
4 PrincipleA pipe of specified length is placed in a liquid bath or air oven at a specified temperature for a specified time .A marked length of this portion of pipe is measured, under identical conditions, before and after heating. The reversion is calculated as a percentage of the change in length in relation to…
