ASTM D8402-23 pdf download – Standard Practice For Development Of Microplastic Reference Samples For Calibration And Proficiency Evaluation In All Types Of Water Matrices With High To Low Levels Of Suspended Solids.

The present protocol outlines innovative techniques for fabricating microplastic beads from standard polymer pellets, as well as the process of creating benchmark microplastic samples. These samples are essential for calibrating and assessing the effectiveness of microplastic recovery, processing, and analytical techniques.

The protocol does not include instructions for manipulating the morphology of the microplastic beads. The methods employed tend to produce particles with varied shapes, which can be advantageous in mitigating analytical prejudices associated with the use of uniform, manufactured spherical beads. For applications requiring spherical particles or fibrous shapes, alternative methodologies should be sought.

Furthermore, this protocol does not address the disposal of waste material produced during its implementation. It is imperative that users adhere to all relevant legal and regulatory standards in the production and disposal of microplastic particles. Users are also encouraged to develop comprehensive waste management protocols to reduce the environmental impact of waste generation.
