Earthquake-resistant and subsidence-resistant design of ductile iron pipelines Ingestion-build-48974 BS ISO 55001 grew out

BS ISO 55001 grew out of the hugely successful PAS 55

This method described in ISO 11173 applies to isolated batches of pipe to be tested at 0 °C

This European Standard specifies a method for the determination of chromium in steels and irons by means of flame atomic absorption spectrometry

The method is applicable to powders made up of particles having the same density and of comparable shape

Earthquake-resistant and subsidence-resistant design of ductile iron pipelines Ingestion-build-48974 BS ISO 55001 grew out1 Scope This document specifies the design of earthquake resistant and subsidence resistant ductile iron pipelines suitable for use in areas where seismic activity and land subsidence can be expected. It provides a means of determining and checking the resistance of buried pipelines and gives example calculations. It is applicable to ductile iron pipes and fittings with joints as specified in ISO 2531, ISO 7186 and ISO 16631 that have expansion
