ASTM E161-17

Standard Specification for Electroformed Material and Test Sieves

ABSTRACT
This specification covers the requirements for design and construction of electroformed sieves. These sieves are used to perform particle-size distribution analysis and in preparing narrowly designated particle-size fractions. They may also be used as reference standards when suitably calibrated. The material used in the manufacture of the sieve sheet shall be nickel or a metal suitable for electrodeposition in a firm crystalline structure. The sheet shall have square or round openings with straight uniform sides and smooth, flat surfaces except for a slight bevel along the edges of the openings. Frames for precision electroformed sieves shall be made from non-corrosive material such as brass or stainless steel, and constructed in such a manner as to be rigid.
SCOPE
1.1 This specification covers the technical requirements for design and construction of electroformed sieves and sieve material. These sieves are used to perform particle-size analysis and in preparing narrowly designated particle -size fractions. They may also be used as reference standards when suitably certified. The method of certifying these sieves is included in Annex A1.  
1.2 The values stated in SI units shall be considered standard for the dimensions of the electroformed mesh openings and the size of the line width in the electroformed mesh. The values stated in inch-pound units shall be considered standard with regard to the sieve frames and to lines per unit length, as in Table 1. The values given in parentheses are mathematical conversions that are provided for informational purposes only, and are not considered standard. (A) These nominal size openings are from the preferred number series R40/3 and R10. (Openings on apertures 32 μm and less are series R10.) These standard designations correspond to the values for test sieve apertures recommended by the International Organization for Standardization (ISO). These sizes are typical, other opening sizes are available.(B) Because of their greater durability in routine testing, sieves made close to the minimum limit are normally supplied. Sieves made close to the maximum limit may be obtained only on special order but are preferable from the standpoint of logical progression and better test completion time.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

NOTE 1—Complete instructions and procedures on the use and calibration of testing sieves are contained in ASTM Manual 32. This publication also
contains a list of all published ASTM Standards on sieve analysis procedures for specific materials or industries.
1.2 The sieve analysis results from two testing sieves of the same sieve designation may not be the same because of the
variances in sieve opening permitted by this specification. To minimize the differences in sieve analysis results, the use of testing
sieves matched on a performance basis is suggested.
