What is ISO 349 about?
ISO 349 specifies a method for determining the swelling properties of hard coal when heated under standard conditions in a dilatometer.
ISO 349 specifies test methods of Audibert-Arnu dilatometer test
In principle, the test is not designed, nor can it be used, to indicate the pressures exerted by hard coals on the walls of industrial carbonization ovens.
Who is ISO 349 for?
ISO 349 on Audibert-Arnu dilatometer test is beneficial for
- Coal producer
- Coal testing laboratory
Why should you use ISO 349?
The Audibert-Arnu dilatometer test is used to determine the coking properties of hard coal or hard coal blends on the laboratory scale.
ISO 349 provide guidance on Audibert-Arnu dilatometer test, apparatus, preparation of the test sample, test procedure, test report required to determine the swelling properties of hard coal
As a user of ISO 349, you can be ensured of the coking properties of hard coal or hard coal. ISO 349 helps the user in performing the Audibert-Arnu dilatometer test efficiently. ISO 349 can assist the user in producing good-quality coal.
What’s changed since the last update?
BS ISO 349:2020 cancels and replaces the first edition (ISO 349:1975), which has been technically revised. The main change done is Reformatting the figures in the main document and annexes.
