| Overview | |
| Test Sieves with stainless steel frames and openings from 5 micron | |
 |
Our test sieves with frames made from stainless steel are equipped with woven wire cloth or robust plates with square perforations according to DIN ISO 3310. If you emphazise closer tolerances our “Gold” Test Sieves are perfect. Test sieves with electroformed sheets are mainly used for finest materials with particle sizes from 5 micron. |
| Conforming to international standards | |
| Fabricated according to valid standards: ISO 3310, ASTM E11, DIN ISO 3310, BS ISO 3310, ISO 5223 etc. |
|
| Your advantages at a glance | |
| • A particularly smooth surface of frames prevents cross-contamination. • An extremely stable sieve structure guarantees a long life. • The sieve fabric retains its tension exceedingly well even after intensive use. • Compatibility with equivalent test sieves manufactured in accordance with current standards. |
|
| Technical data | |
| We provide sieve media of electroformed sheets with aperture sizes from 5 micron up to 500 micron, sieve media of woven wire cloth with aperture sizes from 20 micron up to 125 mm and perforated plates made from galvanized steel* with openings from 4 mm up to 125 mm.
*Sieves with perforated plates made from galvanized steel have to be stored in a dry place and must be cleaned and dried after use. |

| Applications | |
| Application examples for test sieves with stainless steel frames | |
 |
Our test sieves with frames made from stainless steel are suitable both for hand sieving as for dry and wet sieving with all our test sieve shakers. |
| Bulk material of different branches can be classified and separated with these test sieves. | |
| • Industrial rocks and minerals • Food • Glass • Ceramic • Granulates • Powders • Fertilizer |
|
| Please do not use alkaline cleaning liquids to clean HAVER test sieves, otherwise the durability and function of the adhesive seam is no longer guaranteed. We recommend the HAVER USC cleaning liquid “Mehrzweckreiniger S”. |

| Inspection certificate 3.1 | Statement of compliance with the order, with indication of results of specific inspection. |
 |
The free certificate of works 2.1 according to DIN EN 10204 supplied with test sieves basically certifies that the sieves are manufactured in compliance with the requirements for quality assurance according to ISO 9001. |
 |
On request we also issue acceptance test certificates 3.1 according to DIN EN 10204. For this a certification or calibration must be carried out. During calibration, three times more meshes are measured than during certification. The measurement results are stored and are available for later control measurements. |

 |
Ever increasing tougher demands that go beyond the normal standards are now being placed on the reliability of test sieves in an increasing number of application areas. Haver & Boecker meets these demands and, since June 2013, has become Germany’s first accredited calibration laboratory for test sieves of metal wire cloth as to DIN EN ISO / IEC 17025. The calibration certificates for test sieves of metal wire cloth serve as proof of conformance to national and international standards and are recognised internationally by the signatory states within the scope of conventions (EA, ILAC, etc.). |
| DIN EN ISO/IEC 17025 | |
| This standard contains all requirements to be met by testing and calibration laboratories to manage quality (min. According to DIN EN ISO 9001) and technically competent and able to generate technically valid results to prove. The calibration of test sieves with woven wire cloth according to DIN EN ISO / IEC 17025 expands the current review of test sieves with inspection certificate 3.1 according to EN 10204. The uncertainty mentioned in the calibration certificate is used in the subsequent use of the measuring instrument for correcting of the readings. | |
| Requirements for competence in testing and calibration laboratories as to DIN EN ISO / IEC 17025 | |
| • Assurance of expertise and competence • Quality management according at least to DIN EN ISO 9001 • Transparency of measurement results • Measurements under clean room conditions • Measurement results that are expertly based • Indication of measurement uncertainties • Traceability of used measurement devices to national / international standard |
