Abstract / scope
ISO 27588:2008 specifies a dead-load method for the determination of the hardness of very soft vulcanized or thermoplastic rubbers.
The relation between the depth of penetration and the VLRH scale is linear.
ISO 27588:2008Withdrawn
Rubber, vulcanized or thermoplastic — Determination of dead-load hardness using the very low rubber hardness (VLRH) scale
Caoutchouc vulcanisé ou thermoplastique — Détermination de la dureté sous charge constante au moyen de l'échelle de très faible dureté (VLRH)
