Plastics. Determination of apparent density of moulding material that cannot be poured from a specified funnel.

A portion of 60 g of loose moulding material is dropped little by little into a measuring cylinder as evenly distributed as possible. A plunger with specified mass fitting to the measuring cylinder is slowly lowered until it is entirely supported by the material. After 1 min the volume of the material with the plunger resting upon it, shall be determined and the apparent density shall be calculated.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
