Particle & Surface Sciences have announced that its test sieves meet all the requirements of NATA and can be supplied with UKAS certificates.
P&S test sieves for particle size analysis are manufactured with stainless steel frames, woven wire mesh or perforated plate. P&S also supply grain sieves, half height sieves and wet washing sieves. The test sieves are specifically designed and tested to work with concrete, aggregates, soil, bitumen, cement, mortar - in fact most of the materials that will be used in any construction project. P&S standard test sieves are available in frame diameters from 100mm, 200mm, 300mm to 450mm for Australian/European specifications and 8 and 12 inch for American specifications.
The sieves are certified to international standards BS410, ISO3310/1, ASTM E11, NAMAS 0419 and UKAS traceability. Each precision sieve has seamless frames and is individually welded to eliminate the wire cloth detaching itself from the pan. Using an optical measurement technique, each sieve is subjected to a strict quality control procedure, the diameter of wire and strength of metal frames are all checked. Included with all sieves are Certificates of Conformity. In order to check the test sieves, P&S are able to supply glass beads for reference purpose.
