BS ISO 10119:2020

What is ISO 10119 about?

ISO 10119 is an international standard on carbon fibre which covers its determination of density.

ISO 10119 specifies four methods for the determination of the density of carbon fibre tested as a yarn:

• Method A: liquid-displacement method
• Method B: sink/float method
• Method C: density-gradient column method
• Method D: gas pycnometer method.

Gas pycnometer method uses inert gas instead of liquids to measure the volume of fibres, powders, and cellular materials so as to obtain the density. The method gives a much higher resolution (i.e., a factor of 100 times better).

Who is ISO 10119 for?

ISO 10119 on the density of carbon fibre is relevant to:

• Manufacturer of carbon fibre
• Automobiles and sporting goods industry
• Aerospace and medical industry

Why should you use ISO 10119?

Density is a parameter that characterizes the basic physical properties of carbon fibre and is also an important parameter for calculating the tensile strength and tensile modulus of carbon fibre.

ISO 10119 provides the general requirements for the preparation and conditioning of test specimens.

Overall, ISO 10119 let you manufacture carbon fibre making it more durable to use and to ensure density, strength, stiffness, corrosion resistance and environmental safety.

What’s changed since the last update?

BS ISO 10119:2020 supersedes BS ISO 10119:2002. BS ISO 10119:2020 includes some technical changes with respect to BS ISO 10119:2002.

These include:

• Gas pycnometer method (method D) has been added
• The calibration of the measurement cell and expansion cell has been added.
