Some terms and definitions in GB/T.20103-2006.
3.1
Ultrafiltration membrane
It consists of a very thin epidermal layer that acts as a separation and a thicker supporting sponge or finger-like porous layer.
Hundreds to millions of membranes.
[GB/T.20103-2006, definition 5.1.1]
3.2
Breaking tensile strength breakingelongationforce
The ratio of the breaking strength of the hollow fiber super/microfiltration membrane to its linear density.
[HY/T 213-2016, Definition 3.3]
3.3
Elongation at break elongation
The percentage of the initial length of the hollow fiber super/microfiltration membrane resulting from the increase in length of the fracture.
[HY/T 213-2016, Definition 3.3]
3.4
Burst strength burstingstrength
A fluid pressure perpendicular to the membrane surface is applied to the membrane surface, and the critical pressure at which the membrane begins to rupture.
3.5
Flexural strength flexuralstrength
The maximum stress that the membrane can withstand under bending loads or when it reaches the specified deflection.
