EN 826 Determination of Compression Behavior of Thermal Insulation Products
This European Standard specifies the equipment and procedures for determining compression behavior of test specimens. It is applicable to thermal insulating products for building application. It can be used to determine the compressive stress in compressive creep tests and for applications in which insulation products are only exposed to short term loads.
Place the test specimen centrally between the two parallel plates of the testing machine. Compress the test specimen with the movable plate at a constant speed of displacement which shall be d/10 per minute with a tolerance of ± 25 %, where d is the its initial thickness of the test specimen expressed in millimetres. Continue compression until the test specimen yields, providing a compressive strength value, or until a relative deformation of 10 % has been reached, providing a compressive stress at 10 % relative deformation.
We suggest using a tensile testing system of dual-column tabletop design together with the test fixture specimen dependent and selectable.
Test fixture: One set of compression anvils to meet the standard for testing specimens up to 300mm x 300mm. The upper anvil includes having a spherical seat to ensure that only axial force is applied on the test specimen.
- 50mm x 50mm
- 100mm x 100mm
- 150mm x 150mm
- 200mm x 200mm
- 300mm X 300mm
For this test type, we use the specimen protect feature of Bluehill when loading the specimen into the machine to prevent any overloading of specimen during this process prior to test. We then in the test method drive to a preload to eliminate any slack in the specimen then test to failure is carried out. For this test, it is important to have a high-speed intelligent test data sampling rate of 100 Hz to the PC ensure the capture and record of the maximum compressive strength.
We recommend using Bluehill test software package to input specimen parameters, set the desired speed control, automatically calculate the desired results and statistics, and finally to product a test report or send to a network database We suggest reviewing EN826 to fully understand the test fixture and results requirements prior to performing any tests.
Bluehill Universal은 기초부터 터치 인터페이스를 위해 구성되었습니다. 꼼꼼하게 짜여진 디자인과 새로운 세로 방향의 레이아웃은 통합 컨트롤러를 갖춘 대형 터치 모니터를 이용하여 작업자 대시보드에서 시험 작업영역을 포괄적으로 확인할 수 있도록 합니다.
