Tests for geometrical properties of aggregates - Determination of particle size distribution. Sieving method1 Scope This European Standard describes the reference washing and dry sieving method used for type testing and in case of dispute, for determination of the particle size distribution of aggregates. For other purposes, in particular factory production control, other methods may be used, provided that an appropriate working relationship with the reference method has been established. It applies to all aggregates, including lightweight aggregates, up to

The primary focus is on the determination of the characteristic in situ compressive strength for application with EN 1990 and EN 1992-1-1

ISO 307 specifies a method for the determination of the viscosity number of dilute solutions of polyamides in certain specified solvents

and the HEMP simulator tests conducted by many countries during the years after atmospheric testing ended

the external power supply efficiency

BS EN 50124-1 provides the best industry guidance on the basic requirements for the clearances and creepage distances for all electrical and electronic equipment to minimize hazardous situations and ensure the safety of workers

you can benefit from the guidelines given in BS EN 50216-4 to improve the quality and functioning of the transformers and reactors as well as achieve more output

PVC-P compound

This European Standard is applicable in the range of water vapour content from 4 % to 40 % as volume concentrations and of water vapour mass concentration from 29 g/m3 to 250 g/m3 as a wet gas

With obedience and compliance to BS EN 61603-7

This calculation method is applicable regardless of any geographical concern
