ISO 5071-1:2021 PDF Download

A two-furnace method for identifying volatile content in an analytical sample of brown coals and lignites is described in ISO 5071-1:2021.

When evaluating these forms of coal's quality and suitability for different uses, including combustion or gasification, volatile matter is a crucial factor. This standard offers a methodical and accurate way to determine how much volatile material is contained in a certain sample.

This standard's two-furnace method uses a two-stage heating procedure that enables the separation and measurement of several volatile components. The sample is heated further in the second furnace to release the volatile material, while the first furnace is used to remove the sample's moisture content. The gathered and quantified evolved volatile components are then used to provide quantitative data for analysis.

The ISO 5071-1:2021 standard provides a standardised method for calculating volatile matter in brown coals and lignites, ensuring the accuracy and comparability of test results. This makes it possible for users, like coal producers, academics, and regulatory authorities, to make defensible decisions using trustworthy and consistent data.
