Test sieves with square apertures according to ISO 3310-2 are employed in a number of industrial and analytical areas, primarily for the determination of grain-size distribution in soils for stability assessments, grain-size determination in coarse aggregates for use in road and building construction as well as a number of other areas where grain sizes are of importance. Blau-Metall test sieves are of robust construction using only stainless steel components and a rigorous optical inspection protocol guarantees the compliance with tolerances specified in national & international standards, increasing confidence in a statistically sound sieve analysis.

⚙ Robust stainless steel construction of frame and perforated plate for long lifetime and costant sieving results (Frame, tensioning ring & perforated plate consist of 1.4301 stainless steel)
⚙ High-Precision Apertures compliant with ISO 3310-2 / ASTM E 323
⚙ Smooth frame surface prevents cross-contamination & simplifies sieve cleaning
⚙ Ease of use: Blau-Metall Sieves are compatible with comparable sieves of other manufacturers
⚙ Individual laser engraving & serial numbers enable full traceability of Blau-Metall sieves

Blau-Metall test sieves according to ISO 3310 comply with all requirements for laboratory analysis, hand sieving, machine sieving, wet & dry sieving. For every Blau-Metall test sieve, a Certificate of Compliance (EN 10204 2.1) is provided and an Inspection Certificate 3.1 saved in our records and can be issued at a later date. For additional statistical certainty of your sieve analysis, Blau-Metall offers calibration services for test sieves for which data will be documented in a Calibration Certificate 3.1.
