BS EN 933-2:2020

What is BS EN 933‑2 about?  

BS EN 933‑2 is the second part of the BS EN 933 series of documents that specifies the nominal size of apertures for test sieves used for the determination of the particle size of aggregates. 

NOTE: BS EN 933‑2 applies to: 

• Test sieves of a perforated metal plate having square holes of size from 4 mm and up to 125 mm 
• Test sieves of metal wire cloth having aperture sizes below 4 mm down to 0,063 mm. 

Who is BS EN 933‑2 for? 

BS EN 933‑2 on particle size distribution for test sieves is relevant to: 

• Civil engineers 
• Builders 
• Test sieve manufacturers 
• Aggregates manufacturing industry 

Why should you use BS EN 933‑2?  

A test sieve is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample. BS EN 933‑2 gives the determination of particle size of aggregates through test sieves. 

BS EN 933‑2 provides the requirements for applicable test sieves with a nominal aperture size of 4 mm and above that have a perforated plate with square holes. 

BS EN 933‑2 gives the nominal size of apertures for applicable test sieves along with the principal series of nominal sizes of apertures for test sieves. 

Furthermore, BS EN 933‑2 assists you with the test sieves utilized to identify the particle size of aggregates that comprise of different sizes (fine and coarse) that will enable your building structure to be stronger and more durable. 

What’s changed since the last update?  

BS EN 933‑2:2020 supersedes EN 933-2:1995. BS EN 933‑2:2020 includes some technical changes with respect to EN 933-2:1995. These include: 

• The addition of Table 1 "Applicable test sieves – Nominal size of apertures”
