Regularly used test sieves will eventually suffer from 'wear and tear' – which can mean inaccurate results. Sieves should therefore be re-inspected at appropriate intervals to ensure they continue to comply with their intended specification. In fact, regular Re-certification is essential if test sieves are to meet the requirements of the test sieve specification.
Endecotts Re-certification Service is designed to meet the needs of the modern laboratory or testing station that requires an inexpensive sieve re-examination and certification service.
Endecotts Recertification Service includes:
- A visual check for broken wires or damaged mesh, confirmation that the tension is satisfactory, and excessive blinding and pegging.
- A visual check of solder joints for crevices.
- A gauge check on the diameter and roundness of the sieve frame and rim.
- Measurement of the mesh for compliance to the appropriate current specification using calibrated apparatus suitable for the aperture size and sieve medium.
- A summary of the certification status of the re-certified sieves.
- Appropriate certification.
- Should you only require mesh inspection, please specify this on your Purchase Order, we will then omit points 2 and 3 (applies to compliance certificates only.)
- Compliant sieves will be:
- Recertified in line with your requirements.
- Place in a polythene bag, re-boxed and labelled appropriately.
Rejected sieves
- Sieves not passing at standard tolerance will be returned with the box labelled as "FAIL".
- The examination will normally take 7 - 10 working days, once the order is issued to the Inspection Department. Please allow additional time if payment will be by Proforma.
- All Sieves with single woven wire mesh or square hole perforated plate can be returned for re-calibration or re-inspection.
PLEASE NOTE THAT SIEVES WITH BACKING (SUPPORTING) MESH OR SIEVES WITH ROUND HOLE CANNOT BE RE-CALIBRATED OR RE-INSPECTED!!! - Please note that sieves for Re-certification must be clean and free from sample contamination, blinding and, so far as possible, pegging. (Excessive blinding or pegging of apertures may cause the sieves to fail).
- Sieves for Re-certification must be returned in line with our Returns Policy.
