ASTM D6288-17 + Redline

1.1 This practice describes a procedure for separating recycled plastics based on their color and a procedure for washing dirty, ground plastic, which results in separation of light materials (density <1.00 g/cm³). This practice is not intended to represent generic washing procedures used in the plastics recycling industry. The described procedures are solely for preparation of plastic samples for use in other analytical tests. The procedure includes a room temperature wash step to facilitate separation of paper (for example, labels) followed by washing at an elevated temperature.
