This document defines visual aspects for the identification and assessment of product characteristics for friction materials in terms of quality and for commercial and technical agreements. The sequence of the product characteristics represents no order of priority. Inspection is carried out in unused, “as supplied” condition.
In some characteristic features, there are differences between brake…
Clean cookstoves and clean cooking solutions — Test protocols for institutional cookstoves
This document provides testing methods to evaluate the energy performance, emissions, safety and durability of institutional cookstoves. For general guidance (not a requirement), institutional cookstoves typically have firepower greater than 10 kW and/or cooking vessel volume greater than 25 l. The evaluation of household cookstoves is covered in ISO19867-1 and ISO19869 and is not addressed in…
Road vehicles — Application of predictive maintenance to hardware with ISO 26262-5
