Paper and board. Determination of roughness/smoothness (air leak methods) - Bendtsen method1 Scope This part of ISO 8791 specifies a method for the determination of the roughness of paper and board using the Bendtsen apparatus. This part of ISO 8791 is applicable to paper and board which have Bendtsen roughness values between about 5 ml min and 3 000 ml min when measured with variable area type testers and between about 50 ml min and 5 000 ml min when measured with electronic type testers. It is not suitable for soft papers which allow the

up to a gross vehicle mass of 3 500 kg

that facilitates the provision of adequate service quality for all connected end-users

This method in BS 5218 is applicable to:

Why should you use BS EN 3896- Steel FE-WM1501 for aerospace applications

10 Provision against electrolyte hazards

Annex B (normative) Preventative maintenance

and it is not the intention of this International Standard to replace nor redefine those mechanisms

This International Standard describes a procedure for the determination of the following antidegradants in raw synthetic rubbers:

BS EN 61988-3-1 defines drawings and required dimensions of PDP modules

BS ISO 11231:2019 includes some technical changes with respect to BS ISO 11231:2010

It specifies the requirements for:

which display dynamic properties over an extended frequency range at different temperatures
