    ... with Woven Wire ClothTest Sieves are supplied with wovenwire cloth with aperture widths from20 m to 125 mm.

    HAVER Test sieves excell in- a perfect tension even after

    intensive use,- a long service life,- a smooth frame surface avoiding

    cross-contamination.

    ... withPerforatedMetal PlatesSquare hole plates canbe supplied in holewidths from 4 mm to125 mm. They haveproved especiallyefficient in the rangefrom 16 mm hole widthupwards.

    Test sieves with squarehole plates are mainlyused for sieving concreteaggregate materials, roadconstruction stones, natural sand, gravel,brush a.o.

    ... with Electroformed SheetsTest sieves with electroformed sheets are mainly used withhole widths from 5 mm to 100 m.

    They are standardized up to 500 m hole width. They areextraordinarily precise, though mechanically very sensitive.

    These electroformed nickel-foils have round or square holeswidth wide bridges.

    HAVER Test Sieves are fabricated according to the valid standards: ISO 565, DIN ISO 3310, ASTM E 11, BS 410,AFNOR, NEN 2560, ISO 5223 etc. Our International Test Sieve Comparison Table 2003 (see pages 14 + 15) gives ageneral idea.

    HAVER Test Sieves are supplied with woven wire cloth, perforated metal plates or electroformed sheets.

  • 3Certification and Re- Certification of Test SievesDIN EN ISO 9000 ff

    Measuring instruments, includingtest sieves, have to be serviced,tested and labelled at regularintervals. HAVER & BOECKERoffers the opportunity to check testsieves by a video-analysis-systemat our works laboratory. As a special Service we can checkyour test sieves on-site.

    There are two types of tests thatlead to a) a certification or b) to a calibration. Certification and calibration differ in the achiechedreliability levels of test results. The number of measured aperturesizes for a calibration is three times higher than for a certification.

    Test results are statistically interpreted and documented in a certificate of compliance with the standard according to DIN EN 10 204.

    HAVER Grid Sieves with parallel barsaccording to DIN EN 933-3

    Grid sieves are used for the deter-mination of particle shapeflakinessindex of aggregate particles.HAVER Grid Sieves are made of an anodized aluminium frame 300 x 300 mm and stainless steel rod bars.Slot widths are offered from 2.5 mm to 40 mm, according to DIN EN 933-3.

    HAVER test sieves excell in accuracy and stability. The optimumtension of the sieve bottom guaranties a long service life.

    Sieve bottoms (woven wire cloth or screens, perforated metal plates or electroformed sheets) are fixed to the tension ring by soldering,welding or using adhesives. The tension ring is pressed into the frameand sticked to it. Sieve bottoms made from woven wire cloth with 20 m to 45 m aperture width are usually fixed with their downsideto the tension ring. The careful fabrication guaranties a good service life with perfectoperation.

    To meet the high demands, HAVER & BOECKER carries out regularreceipt and production controlls.Each test sieve gets a certified compliance with the order 2.1according to DIN EN 10204 without extra charge.

    Upon request and with extra charge an inspection certificate Baccording to EN 10204 3.1 B can be provided, too. The test recordrepresents the measuring results of the distribution of apertures intabular and graphic form.

    Auxiliary Parts for Test Sieves

  • 6Test Sieve Shakers and Laboratory EquipmentTest Sieve Shakers are used to separate sieveable products into single fractions. Reproducible test sieve results can be achieved in the shortest possible time. Hand sieving, which is the basis of the total separation technique, can beaccurately replicated.

    HAVER Test Sieve Shakers produce a three-dimensional sieving action. The material is distributed over the whole sieving surface. For difficult products, sudden interruption of the sieving action using intermittent drives intensifies the sieving and in many cases reduces the sieving period.

    HAVER Test Sieve Shakers have no rotating parts, are extremely durable, maintenance free, very adaptable and have a low noise level. Due to the use of a special spring system and cast iron parts, the construction is heavy and sturdy.This avoids unwanted vibrations being transmitted to the stationary parts of the sieve shaker and its stand.
