$\"\"$ <\/a>U.S. Code of Federal Regulations (CFR)<\/strong>

In the United States of America, test sieves and industrial sieves \u2013 their manufacturing tolerances and operational use \u2013 are regulated in differently than in European Standards. Technical specifications for laboratory test sieves are defined through ASTM E 11 for woven wire cloth sieves and ASTM E 323 for perforated plate sieves with round and square apertures. These two technical standards are largely similar to requirements imposed by their counterparts ISO 3310-1 and 3310-2. However, there are a number of exceptions where other technical regulations \u2013 as defined in the U.S. Code of Federal Regulations \u2013 apply and call for less-common sieve dimensions.\n

\nBlau-Metall can manufacture and certify laboratory test sieves in accordance with ASTM E 11 and E 323 and we furthermore offer to our international customers chosen sieves that fall under CFR regulation. As with all other Blau-Metall sieves, our CFR Product Line is manufactured in a robust stainless steel design and employs precision aperture technology to comply with the rather strict tolerances demanded by the CFR. \n

\nCurrently available are the following Blau-Metall CFR Sieves with a frame diameter of 200 mm:<\/strong>
