Rubber Aging Tester
Test Instrument | Rubber Aging Tester |
Capacity | MAX TEMP. 150°C |
Test Standard | KS M 6518,8 |
Test Method | After mounting rubber specimen into the tester, maintain the temperatureof its inner core at 100 ± 1’C for 96hours, leave it undisturbed at room tem-perature for 16-96 hours. During maintaining room temperature, measurethe tensile strength, elongation percentage and hardness. |
Test Purpose | Measuring the aging of rubber caused by heat: comparing data of“before and after'” the test |
Electric Fumace
Test Instrument | Electric Furnace |
Capacity | MAX TEMP. 1600C° |
Test Standard | Accofdirg to the method designated by user |
Test Method | According to the Method designated by user |
Test Purpose | Testing to determine the heat treatment condition of raw metal materials and prototypes. |
Rubber Restoring Force Tester
Test Instrument | Rubber Restoring Force Tester (Thermostat) |
Capacity | MAX TEMP. 100T |
Test Standard | KS M 6518,11 |
Test Method | Pressing at a specific ratio of the thickness of the rubber sample, and main-taining it at 100 ± TC in a specific period of time; after that, measuring the thickness of the cooled robber after removing from the pressing device |
Test Purpose | Comparing between data before and after the test to measure the reduction of the rubber by means of heating and pressure |

Capacity | 200 KN |
Test Standard | KWWA D 100-2 ,10.6 |
Test Method | joining a specific length of pipe to our product: after that, adding a specific amount of pressure to the inside to pull away in the direction of the axis |
Test Purpose | Measuring the stopping power against tensile strength of the direction es rpose 0fthe product’s axis |
Tensile Strength Tester
Test Instrument | Tensile Strength Tester |
Capacity | 1000 N |
Test Standard | KWWA D 100-2, 5 |
Test Method | Place the rubber specimen in the grip of tester at a specified gauge length and pull until it breaks, measure the change of gauge length. |
Test Purpose | Using the change of the gauge length before and after the test to measure the largest extension power |
Rockwell Hardness Tester
Test Instrument | Rockwll Hardness Tester |
Capacity | HRA, HRB, HRC |
Test Standard | |
Test Method | Pressing the ‘ndenter of A B, C scale into the surface of the sample at a specified load, measure the resistance of the sample to indentation. |
Test Purpose | Measuring the hardness of the sample |
Shock-Tolerance tester
Test Instrument | Shock-tolerant Tester |
Capacity | |
Test Standard | KWWA 100-2, 10.9 |
Test Method | After joining the pipe and joints, filling the inside with the water, repeatedly pressurize up to specified pressure and deptessurize to 0 for a specific period of time. |
Test Purpose | Testing impact resistance of the joints due to repeated impact |
Vacuum Tester
Test Instrument | Vacuum Tester |
Capacity | |
Test Standard | KWWA 100-2, 10.5 |
Test Method | After joining a specified length of pipe and joint, maintain the inside pressure below atmospheric pressure and check for leakage. |
Test Purpose | Check for the leak-tightness of joints with pipe under vacuum. |
