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