What is ISO 22459 about?
ISO 22459 specifies the conditions for the determination of the distribution of strength and rupture strain of ceramic filaments within a multifilament tow at room temperature by performing a tensile test on a multifilament tow.
ISO 22459 applies to dry tows of continuous ceramic filaments that are assumed to act freely and independently under loading and exhibit linear elastic behaviour up to failure. The outputs of this method are not to be mixed up with the strengths of embedded tows determined by using ISO 24046.
Who is ISO 22459 for?
ISO 22459 on ceramic filaments is useful for:
- Ceramic manufacturers
- Mechanical engineers
Why should you use ISO 22459?
Tensile strength is the ability of a material to withstand a pulling force and refers to the breaking strength of a material when a force capable of breaking many strands is applied to the material simultaneously, at a constant rate of extension/load. It is customarily measured in units of force per cross-sectional area.
Tow testing provides a statistically valuable database of flaw strength data for failure analysis and reliability assessment for fibers.
Determining the distribution of strength and rupture strain of ceramic filaments can be crucial to understanding the properties and strength of the particular ceramic, ISO 22459 provides you with the conditions for this determination. Having more knowledge about your product helps you in increasing efficiency within your organization.
