Materials of Construction
Newark Wire Cloth’s Stainless Steel Test Sieves are manufactured using 300 series stainless steel. Unless otherwise specified the sieve frames are manufactured using 304 SS. They can also be fabricated using either 304L SS, 316 SS or 316L SS but these would be considered a special order. The ASTM E11-24 Sieve Cloth is typically supplied in 304 SS, but is often available in 304L SS, 316 SS, or 316L SS. If a 300 series stainless steel other than 304 SS is required please check with one of our customer service sales consultants as to its availability.
Historically, as all Test Sieves users know, Test Sieves have been offered in (3) different material combinations; all Stainless Steel, all Brass, or with a Brass Frame and Stainless Steel Cloth. Newark Wire Cloth recently discontinued our all Brass Test Sieves, and our Brass Frame with Stainless Steel cloth Test Sieves product offerings for the following reasons –
- For years Brass had been less expensive than Stainless Steel. However, in today’s metals market the price of Brass (due to its Copper content) has gradually caught up to, and passed Stainless Steel material costs.
- Many of the ASTM E11-24 specifications are woven in Stainless Steel only.
- Brass oxidizes, meaning it tarnishes over time; any Brass sieves in stock, need to be polished a second time before shipping. Customers are not expecting their new Brass sieve to be tarnished when they receive it.
- Stainless Steel is more durable in terms of abrasion resistance. Brass is a ‘softer’ metal.
- Stainless Steel is more corrosion resistant than Brass.
- Stainless Steel is preferred for wet sieving and for food and pharmaceutical applications.
- Stainless Steel is also ‘stronger’ and preferred for larger diameter test sieves.
Test Sieve Certification & Re-Certification
Be Certain Your Test Sieves Measure Up!
- Today’s Test Sieves are digitally inspected; openings are measured with a computer aided optical video imaging system linked to custom statistical software.
- Measurement system is regularly calibrated to NIST traceable standards.
- Test Sieves can be supplied certified or re-certified to ASTM E11-24 or ISO 3310 Specifications.
- Certification and Re-Certification reporting is presented graphically in a Histogram. Certification also includes statistical summary information.
- Each Test Sieve is identified with a serial number and supplied with NIST traceable documentation.
- Each Test Sieve is individually boxed.
ASTM E11-24 Test Sieves now manufactured to (3) different confidence levels.
Compliance Test Sieve
Supplied to a confidence level of 66%, means that the sieve cloth used in this test sieve was inspected prior to being mounted in the sieve frame; and that it meets the requirements as outlined in Table 1, Column 7 of the ASTM E11-24 Specification.
A Certificate of Compliance is included with the Test Sieve when it is shipped. There is no statistical documentation supplied with a Compliance Test Sieve.
Inspection Test Sieve
Supplied to a confidence level of 99%, means that the sieve cloth used in this test sieve was safely inspected and measured after being mounted in the sieve frame; and that it meets the requirements as outlined in Table 1, Column 9 of the ASTM E11-24 Specification.
The documentation certificate for an Inspection Test Sieve includes (at a minimum) the average opening size when measured in both the warp and shute direction of the sieve cloth.
Calibration Test Sieve
Supplied to a confidence level of 99.73%, means that the sieve cloth used in this test sieve was inspected and measured after being mounted in the sieve frame; and that it meets the requirements as outlined in Table 1, Column 11 of the ASTM E11-24 Specification.
Calibration Test Sieves have at a minimum (for test sieves with a 3/4” opening and smaller) twice as many openings measured as Inspection Test Sieves. For US Std #400 and finer three times as many openings are measured than the Inspection Test Sieves.
The documentation certificate for an Calibration Test Sieve includes (at a minimum) the number of openings and wire diameters measured, the average opening size and average wire diameter when measured in both the warp and shute direction of the sieve cloth, and the standard deviation.

How to order
Test Sieves
Ordering our sieves is simple, we can return a quote to you within a couple hours if you supply this information. Note that if you have a precise part number, you may just send that but otherwise any of the following info will help us quote you quickly.
- Sieve Diameter
- Mesh size or micron size (Ex. #20 or 850 um)
- Whether or not you need brackets, if so how many and how long should they span? (Ex. 4 brackets spanning 4″ each.)
Of the aforementioned info, sieve diameter and mesh or micron size is the most important. Our industry experts look forward to hearing from you and best meeting your sieve needs.
