Determination of particle size distribution by gravitational liquid sedimentation methods - General principles and guidelines1 Scope This part of ISO 13317 covers methods for determining the particle size distributions of particulate materials, typically in the size range 0,5 m to 100 m, by gravitational sedimentation in a liquid. NOTE This part of ISO 13317 may involve hazardous materials, operations and equipment. This part of ISO 13317 does not purport to address all the safety problems associated with its use. It is the responsibility of the user of this part of ISO

BS EN 115-1:2008+A1:2010 Safety of escalators and moving walks

This document is applicable to uncontrolled fires

implementation and management of controls taking into consideration the organization’s information security risk environments

With the help of the Teletext transmission requirements

test fuels

ISO 17089-1 focuses on meters for custody transfer and allocation measurement (class 1 and class 2 meters)

BS EN IEC 60665 specifies the performance and the corresponding methods of test of AC ventilating fans for household and similar purposes intended for air forcing and exhaust

it would be better to consider the items just as conforming or not
