Rubber, vulcanized or thermoplastic - Determination of tear strength - Part 2 : small (Delft) test pieces

ISO 34-2:2007 specifies a method for the determination of the tear strength of small test pieces (Delft test pieces) of vulcanized or thermoplastic rubber. The method does not necessarily give results agreeing with those given by the method described in ISO 34‑1, which uses trouser, angle and crescent test pieces. It is used in preference to ISO 34‑1 when the available material is limited, and may be particularly suitable for testing small finished products.

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.
