Test Sieves Built to ASTM E11 and ISO 3310-1

Stainless steel laboratory test sieves, manufactured in-house at our Yongkang plant. Send us the standard, the frame diameter and the aperture you need, and we will quote against your specification — not against a catalogue that nearly fits.

Made to your standard

ASTM E11 or ISO 3310-1 — tell us which one your laboratory reports against. The two differ in aperture tolerance and in how the frame is marked, so we build to the one you name rather than substituting.

Certification on request

Inspection, calibration or certified-grade documentation, matched to what your quality system requires. Say what the auditor asks for and we will confirm what we can supply before you place the order.

A metal-forming factory, not a trader

The same Yongkang plant that presses 500,000 bakeware units a month. Frames, mesh mounting and finishing happen in-house, which is why a non-standard diameter is a quotation rather than a refusal.

What to send with your enquiry

A test sieve quotation turns on four numbers. With them we can price in 24 hours; without them any figure we give you is a guess.

Sourcing kitchen sifters and strainers instead? Those are a different line — see the 304 stainless flour sieve and the fine-mesh strainer.

Test Sieve FAQ

Do you manufacture to ASTM E11 or to ISO 3310-1? expand_more
Both. Tell us which standard your laboratory reports against and we build to that one — the aperture tolerances and the frame marking differ between them, so they are not interchangeable.
Can you supply calibration documentation? expand_more
Tell us what your quality system requires — inspection, calibration or certified grade — and we will confirm in writing what we can supply for your specification before you commit to an order.
Will you quote a non-standard frame diameter? expand_more
Yes. We press and finish the frames ourselves, so a diameter outside the usual range is a tooling question we can price rather than an automatic no.
What is the minimum order for test sieves? expand_more
Send your specification and we will quote the sampling quantity with it. Test sieves are quoted per specification rather than off a fixed price list.
Where do you ship from? expand_more
FOB Ningbo. The factory is in Yongkang, Zhejiang, and our showroom is at Yiwu International Trade Market if you would rather inspect in person.
