Sector: Manufacturing

Overview: Under the direction of the Standards Policy and Strategy Committee (SPSC), LBI/37 is responsible for monitoring and contributing to standards developed for the calibration and verification of particle characterisation apparatus. LBI/37 contributes and co-ordinates the UK input to ISO/TC 24 Particle characterization including sieving, ISO/TC 24/SC 4 Particle characterization, and, ISO/TC 24/SC 8 Test sieves, sieving and industrial screens.
