Developing an ASTM standard test method is an arduous process designed to establish a test method for industry while also offering de?nitive precision, accuracy and reliability (PAR) statements. The (PAR) is based on Precision & Bias (P&B) data achieved through an InterLaboratory Study (ILS). An ILS is a mandatory aspect of all ASTM standards that demonstrates how effectively different operators, laboratories and test instruments implement the method, which ultimately de?nes the precision, accuracy and reliability.
