The Complete Guide to Buying Test Sieves in Australia

If you're searching for a complete guide to buying test sieves in Australia, you've come to the right place. Whether you're a geotechnical engineer conducting soil particle analysis, a laboratory technician performing aggregate grading tests, or a grain farmer sorting native seeds, choosing the right test sieve is essential for accurate, compliant, and reliable results.

What Are Test Sieves & Why Do They Matter?

A test sieve (also called a laboratory sieve or analytical sieve) is a precision instrument used to separate and classify particles by size. Using a woven wire mesh or perforated plate, test sieves allow material — soil, aggregate, grain, sand, coffee, pharmaceutical powders and more — to pass through or be retained at specific mesh openings.

In Australian industry, accurate particle size analysis is not optional — it is required by engineering standards, construction codes, environmental regulations, and quality assurance protocols. Using a substandard or uncalibrated sieve can mean inaccurate test data, failed compliance audits, costly rework, or even structural failures in civil engineering applications.

Did You Know?

Many Australian standards — including AS 1289 (Methods of Testing Soils) and AS 1141 (Methods for Sampling and Testing Aggregates) — specify the use of calibrated sieves that meet ISO 3310. Using non-compliant sieves may invalidate your test results.

Understanding ISO 3310 Certified Test Sieves

As part of this guide to buying test sieves in Australia, understanding ISO 3310 certification is one of the most important factors when selecting laboratory sieves for compliant testing.

ISO 3310 is the international standard governing the technical requirements and tolerances for test sieves. In Australia, ISO 3310 certification is the benchmark for laboratory compliance and is referenced in engineering, construction, mining, and environmental testing contexts.

CMT Equipment & Calibrations stocks a comprehensive range of ISO 3310 certified test sieves in 75mm, 100mm, 200mm, 300mm and 450mm diameters — Australia's largest readily available range of stainless steel test sieves.

Woven Wire Mesh

From 38 micron up to 16mm. Ideal for fine soil, pharmaceutical and mineral analysis.

Perforated Plate — Square Hole

Perfect for aggregate, gravel, and large-particle classification.

Perforated Plate — Round Hole

Used in grain sorting, food processing, and construction materials testing.

Wet Washing Sieves

Designed for wet sieve analysis — ideal for clay-rich soils and fine sediment testing.

NATA Calibration: What It Is & When You Need It

NATA (National Association of Testing Authorities) accreditation is Australia's formal recognition of testing competence. When a sieve is NATA calibrated, it means the mesh apertures have been independently measured and verified to meet the specified tolerances — and you receive a traceable calibration certificate to prove it.

If your organisation performs NATA-accredited testing — or if your clients, contracts, or regulators require certified data — you need NATA calibrated sieves. CMT Equipment & Calibrations operates a NATA-accredited calibration facility, offering fast, reliable, and affordable calibration for woven wire sieves from 38 micron to 3.35mm in both 200mm and 300mm diameters.

Who Requires NATA Calibrated Sieves?

Construction contractors, geotechnical laboratories, state road authorities, universities, environmental consultants, mining companies, and government testing departments all commonly require NATA calibration for their test sieves.

Choosing the Right Sieve Diameter for Your Application

One of the most common questions we receive from customers reading our guide to buying test sieves in Australia is, "Which sieve diameter do I need?" The answer depends on the material being tested, sample volume, and the applicable Australian Standard. Here's a quick reference:

Diameter	Common Applications	Typical Users
75mm / 100mm	Small sample analysis, research, quality control checks	Research labs, universities, QC teams
200mm	Fine soil, fine aggregate, pharmaceutical powders	Geotechnical labs, mining, food processing
300mm	General soil grading, coarse aggregate, site testing	Civil engineers, road authorities, construction labs
450mm	Large aggregate, quarry material, bulk sample testing	Quarries, heavy civil, infrastructure projects

A practical guide to buying test sieves in Australia should also consider your industry requirements, testing standards, sample type, and laboratory procedures before selecting the most suitable sieve.

Industries That Rely on Test Sieves in Australia

Test sieves are not limited to laboratories. Across Australia, a remarkable range of industries and professionals depend on quality sieving equipment every day.

Construction & Civil Engineering, Mining & Minerals, Agriculture & Grain Testing, Universities & Research, Government Departments, Coffee & Food Processing, Horticulture & Gardening, Archaeology & Geology, Pharmaceutical & Chemical, Environmental Consulting, Prospecting & Gold Fossicking

With over 18 years of experience, CMT Equipment & Calibrations has supplied sieves to customers across every one of these sectors — from solo prospectors in Western Australia to major infrastructure contractors on the East Coast.

Sieve Shakers: Automate & Standardise Your Testing

Manual sieving is time-consuming and introduces operator variability. A sieve shaker automates the mechanical agitation of your sieve stack, ensuring consistent, repeatable results that meet standard test methods. Whether you need a basic bench-top unit for occasional testing or a heavy-duty shaker for continuous use, CMT Equipment stocks a range of sieve shakers to suit Australian labs and field testing.

Sieve shakers are particularly valuable in high-throughput environments like quality control labs, road construction sites, and materials testing facilities where multiple sieve analyses must be completed daily to a consistent standard.

Sieve Accessories: Complete Your Testing Setup

A reliable test sieve setup requires more than just the sieves themselves. CMT Equipment & Calibrations supplies a full range of sieve accessories including:

• Sieve lids — protect mesh surfaces and contain samples during testing
• Sieve receivers / pans — collect fines that pass the finest sieve
• Sieve brushes — essential for thorough mesh cleaning without damage
• Wet wash sieve frames — for wet analysis with replaceable mesh inserts
• Large screen tray sieves — for oversized or bulk material

Investing in the right accessories extends the service life of your sieves and maintains the integrity of your testing — both important considerations for organisations with NATA accreditation or ISO compliance obligations.
