QUESTION : Amendment 02 states that ASTM and ISO methods are acceptable. Please confirm that a laboratory may propose its accredited standard methods for appearance, pH, conductivity, dissolved solids/dry residue, and ash, provided the methods demonstrate compliance with Appendix A limits. ANSWER : A laboratory may propose its accredited standard methods for each parameter and their ability to demonstrate compliance with the requirements.
