Plastics. Injection moulding of test specimens of thermoplastic materials - Determination of moulding shrinkage Ingestion-build-137917 4 Requirements for trainborne equipmentWhat is this standard about? This document specifies a method of determining the moulding shrinkage and post moulding shrinkage of injection moulded test specimens of thermoplastic material in the directions parallel to and normal to the direction of melt flow. For the determination of shrinkage of thermosets, see ISO 2577. Moulding shrinkage as defined in this document excludes the effects of humidity uptake. This is included in post moulding
