ASTM E 11

This specification covers the requirements for design and construction of testing sieves using a medium of woven wire cloth mounted in a frame for use in testing for the classification of materials according to designated particle size and wire cloth meeting the specifications specified, to be designated test grade wire cloth. Frames for wire cloth sieves shall be constructed in such a manner as to be rigid. The wire cloth shall be mounted on the frame without distortion, looseness or waviness. To prevent the material being sieved from catching in the joint between the wire cloth and the frame, the joint shall be filled smoothly or constructed so that the material will not be trapped. Standard frames for the sieve frames shall be circular with specific nominal diameters. The dimensions shall conform to the specified requirements. These frames shall be made from non corrosive material such as brass or stainless steel and be of seamless construction. The nonstandard frames for sieve frames may be either square, rectangular, or circular. The frame may have the sieve cloth permanently installed, or may be designed to permit replacement. Pans and covers for use with sieves shall be made so as to nest with the sieves. Pans with extended rims (“stacking skirts”) shall be furnished when specified. The pans and covers shall conform to the specified dimensions.
