ASTM E2680-09

1.1 This test method describes the visual assessment of the appearance of clear, transparent liquids for clarity and the presence of undesirable components (contamination) such as suspended matter, free water (or oil) and particulates when examined by transmitted light. Measurements requiring instrumentation are not included in this method. This test method was originally designed for application to glycols and methanol wall washes of marine vessels but may be applicable to other clear transparent liquids.

1.1.1 This method can be used as a field test at storage temperatures or as a laboratory test at room temperatures.

1.1.2 This method provides a rapid pass/fail test for clarity and contamination of clear, transparent liquids. It is a qualitative assessment only.

1.2 Review the current appropriate Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in the section on Hazards, Section 8.
