AS 4489.7.1:1997 (R2016) PDF Download

AS 4489.7.1:1997 (R2016) is a standard that specifically focuses on the test methods used to determine the loss on ignition in limes and limestones. Loss on ignition refers to the weight loss experienced by a sample when it is heated to a high temperature, typically around 1000°C.

The standard provides detailed procedures for the measurement of loss on ignition in different forms of lime and limestone, namely quicklime and hydrated lime. These materials are commonly used in various industries, including construction, agriculture, and manufacturing.

The test method outlined in this standard involves taking a representative sample of the lime or limestone and subjecting it to controlled heating in a furnace. The weight loss observed during this process is then measured and expressed as a percentage, which indicates the amount of volatile matter, carbon dioxide, and water content in the sample.

By providing a standardized and reliable method, this standard ensures that loss on ignition results obtained for limes and limestones are accurate, consistent, and comparable across different laboratories and testing facilities. This information is essential for quality control, product development, and compliance with regulatory requirements in industries that utilize limes and limestones.
