Microstructure of cast irons - Graphite classification by visual analysisWhat is ISO 945 1 Microstructure of cast irons about? ISO 945 is a series of international standards on the microstructure of cast irons that discusses the criteria for graphite classification by visual analysis. ISO 945 1 is the first part of a series of documents on the microstructure of cast irons. ISO 945 1 specifies a method of classifying the microstructure of graphite in cast irons by comparative visual analysis. The purpose of ISO 945 1 is to

in order to comply with the requirement of regular shape

IEC 60076‑8

Provide product intent specifications such as paper media selection and binding information

it is anticipated that further development will result in greater precision in defining terms

The properties are determined on the basis of standardized attributes

this International Standard

Annex B (informative) Transforming results of efficiency tests to the reference point HS

Annex H (normative) - Class FMT: Security management

They make it clear where existing standards can be further used and highlight where standardisation work is needed

Fibre reinforced polymers change from a hard to a more rubbery state at the glass transition temperature
