Standard Test Method for Appearance of Clear, Transparent Liquids (Visual Inspection Procedure)
SIGNIFICANCE AND USE
5.1 This method provides a pass/fail test for appearance of clear, transparent liquids. Many liquid organic products have a product specification requiring them to be clear and bright and free of visible particulate matter and of liquid phases other than the main liquid. Producers of these liquid organic products need a test method to confirm the quality of their products meets product specifications for appearance. Appearance is a manufacturing and sales specification test for ethylene and propylene glycol and polyol products and a loading specification test for methanol wall washes of marine vessels. 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. Individuals using this test method for other clear transparent liquids should assure themselves that the method is sufficient for use.
5.2 There are many factors that could affect the appearance during and after sampling of a liquid product. These factors may include transferring of the liquid into a different sample container, contamination by the sample container or contamination by ambient atmosphere. Sampling and evaluation procedures need to be followed to avoid undesirable effects and assure the appearance of the sample is typical for the liquid as manufactured.
SCOPE
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 Safety Data Sheets (SDS) 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.

For aqueous samples, the determination of free oil is equally important and may have an appearance similar to that of free water
or oil in organic samples.
3.1.4 haze or cloudiness, n—is a scatter of light from an accumulation of tiny suspended particles in the liquid.
