Number Sep 26, Sieving in its most elemental definition is the separation of fine material from coarse material by means of a meshed or perforated surface. The technique was used as far back as the early Egyptian days as a way to size grains. These early sieves were made of woven reeds and grasses. Today the sieve test is the technique used most often for analyzing particle-size distribution. Although at first look the sieving process appears to be elementary; in practice, there is a science and art involved in producing reliable and consistent results. In order to better understand sieving, there are several areas of sieve specification that should be explained. Test sieves are measuring devices used to determine the size and size distribution of particles in a material sample using wire mesh of different openings to separate particles of different sizes. Test sieves usually consist of wire mesh held in a frame. In most laboratory applications, the frame is round and is made from stainless steel or brass. The standard frame sizes are 3- 6- 8-,or in. The woven mesh can be made of stainless steel, brass, or bronze. For most applications stainless steel is the most common material used. The main limitation with the construction of test sieves is the inherent nature of a woven product, including control of sag when mounted and the uniformity of construction of the holding frame. It is also essential to maintain consistent sizing across all the openings in a piece of mesh. Because of the inherent variations of openings in any woven product, there are limitations to the degree of uniformity achieved in the opening size across the mesh in a sieve. This results in a practical limit to the range of openings and to the precision of results from a specific sieve. The sieve test requires particles to pass through the sieve mesh. The first sieve-testing standards were developed by W. Tyler Co. This original work predated any published activity by the standards organizations, and the Tyler designation is the de facto standard in many industries. European standards were developed by a German university group in and are known by the designation DIN These were followed by British Standards BS They were designed to be the universal international standards. However, in practice, all of the aforementioned standards are in operation. Sieve-testing standards relate to the construction of the sieve frame and mesh mounting as well as the tolerances allowed in the variability of mesh openings. Basic principles are common to all of the standards, and variations in terminology and details are small. These small differences, however, can often lead to confusion. The following is a synopsis of the principles behind these standards. Rigid construction 2. Cloth mesh mounted without distortion, looseness, or waviness 3. Joint between mesh and frame to be filled or constructed so that particles will not be trapped 4. Frame made of noncorrosive material, and must be seamless 5. Bottom of the frame sized to easily slide into the top of same-sized sieve, thus enabling stacking 6.

Written by Newark Wire Cloth Company. Wire cloth is a highly versatile material and essential component in manufacturing, but without sufficient quality control standards for cloth production and testing, serious product defects can result leading to a myriad of negative outcomes. ASTM E standards safeguard the production and use of wire cloth and related products, helping stakeholders in the automotive, pharmaceutical and aerospace industries realize better outcomes. The committee has jurisdiction over 29 approved standards and is mandated to develop, produce and maintain standards that enhance quality assurance. The group also creates supplemental practices, guides and terminology that make it easier for manufacturers to implement standards and best practices. E11 was founded in and meets twice a year to coordinate the creation and maintenance of professional guidance. There are 20 members participating in the meetings, but there are approximately committee members. E11 sponsors workshops, seminars and symposia on the use of quality control and statistics associated with approved standards. Many of the standards originally issued by the group are superseded, so determining the active standard is important for compliance and quality assurance purposes. The requirements for the design and construction of testing sieves utilizing a medium woven wire cloth mounted in a testing frame, for use in testing the classification of materials given a designated particle size, are covered in detail. Designated test wire cloth is one of the specified outcomes of this standard. Testing frame construction requirements and cloth mounting specifications are also stated. Frame dimensions, shape, and materials must conform to requirements to meet the standard. For example, frame construction must be made from non-corrosive materials such as stainless steel or brass. Values stated in SI units are standard for the dimensions of sieve cloth, and values stated in inch-pounds are standard for sieve frames, pans and covers. Knowing the correct measurement criteria is critical for compliance. While this standard has a wide scope related to the design and performance of using wire cloth, it is not meant to be all inclusive. Also, operators can look at superseded standards to see how best practices and requirements have changed over time. As a leader in the wire cloth industry, the company follows industry best practices and standards, providing clients with the highest quality products and service. Toggle navigation.
