Explosion Strength

One of the physical tests to determine the durability and quality of textile products is explosion strength. When using fabrics, they are not only in the direction of warp and weft but also under the influence of multiple forces. Therefore, the tensile and tear strength of warps and wefts is insufficient to determine the resistance to these forces. Explosion strength is of paramount importance for parachute cloths, filter cloths, sacks, knitted fabrics and nets used for various purposes.

Burst strength is the amount of fluid pressure required to tear with a sudden force applied to a fabric. While the test is being done, the fabric samples are waited until they are brought to constant air conditioning and humidity conditions of the test environment and then put into the explosion device. An increasing amount of liquid or gas fluid pressure is then applied to the bottom of the fabric sample until it explodes.

For physical tests performed in laboratories, many standards published by domestic and foreign organizations are complied with. In this context, the standards based on explosion strength tests are as follows:

  • TS 393 EN ISO 13938-1 Textile - Bursting properties of fabrics - Part 1: Hydraulic method for the determination of burst strength and burst stress
  • Bursting properties of textile fabrics - Part 13938: Pneumatic method for the determination of bursting strength and bursting stress TS EN ISO 2-2
  • ISO 2960: 1974 Textile - Determination of blasting power and burst distortion - Diaphragm method
  • BS 4768 Method for determining burst strength and burst distortion of fabrics
  • ASTM D3786 Standard test method for burst strength of textile fabrics - Diaphragm burst strength test method

 

The laboratories that will perform explosion strength tests must be accredited from national or international foreign organizations in accordance with the standards of TS EN ISO / IEC 17025 General Conditions for the Competence of Testing and Calibration Laboratories.
