Standard Cancelled

Methods of test for dense shaped refractory products. Part 14 : determination of thermal conductivity by the hot-wire (cross-array) method.

Le présent document définit une méthode de détermination de la conductivité des produits et matériaux réfractaires par la méthode du fil chaud (croisillon). Il s'applique aux produits denses et isolants, ainsi qu'aux matériaux pulvérulents ou granulaires, ceci pour des conductivités thermiques ne dépassant pas 1,5 W/mK. Les produits électriquement conducteurs sont exclus de la détermination.

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.

With Requirements, quickly access the main part of the normative text!
