Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Validating the specifications, value and safety of your raw materials, products and assets. Formally confirming that your products and services meet all trusted external and internal standards. An Ash test is used to determine if a material is filled. The test will identify the total filler content.
It cannot identify individual percentages in multi-filled materials without additional test procedures being performed. An ash test cannot be used to determine the percent carbon 345-11 or percent carbon black since carbon burns off during the Ash test.
A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of both. Six grams of sample is typically used, which represents three crucibles each containing two grams of sample.
Smaller sample weights can be tested but accuracy diminishes with smaller sample sizes. Typically the average of 3 crucibles is reported.
Standards can be obtained from appropriate standard authorities.
