How Accurate Are Test Sieves? 4 Key Factors to Ensure Precision

Test sieves are simple yet crucial instruments for particle sizing and gradation testing.

Their accuracy is not determined by ensuring each opening is exactly the specified size.

Instead, accuracy is achieved through statistical methods that predict overall conformance.

This is done by measuring a certain number of apertures and using statistical forecasting to judge the level of accuracy.

4 Key Factors to Ensure Precision in Test Sieves

How Accurate Are Test Sieves? 4 Key Factors to Ensure Precision

1. Statistical Accuracy and Calibration

Calibration sieves, with about twice as many openings and wires measured as inspection sieves, offer a high level of accuracy with a confidence level of 99.73%.

These sieves are used as references to calibrate working sieves.

This ensures that working sieves maintain the necessary precision for accurate particle size analysis.

Verification of new test sieves can be specified when ordering.

Re-verification is performed to check the performance of used sieves.

This contributes to an internal quality control/quality assurance program.

2. Sieving Agitation and Maintenance

The accuracy and repeatability of test sieve results are significantly influenced by the method of agitation used.

Manual agitation, involving manually shaking the test specimen in one sieve at a time, is known for its poor repeatability and accuracy.

This method does not account for individual technician's physical size, strength, or other factors.

It is also inefficient as it tests samples with one sieve at a time.

Therefore, more controlled methods of agitation, such as using sieve shakers, are recommended for critical applications.

This ensures consistent and reliable results.

3. Variations in Sieve Cloth

Test sieves are made of woven mesh material, and variations in the weave are common.

The likelihood of finding two sieves with an identical distribution of opening sizes is extremely low.

These variations can affect the reproducibility of test results between sieves.

To manage this, stringent standards imposed by organizations like ASTM and ISO establish tolerance factors.

These factors allow for permissible variations in the weave while maintaining a level of uniformity in the performance of 'test grade' sieve cloth.

4. Adherence to Strict Standards

In summary, the accuracy of test sieves is maintained through careful calibration, controlled agitation methods, and adherence to strict standards.

While it is not feasible to guarantee the exact size of each individual opening, these practices ensure that test sieves remain reliable and accurate scientific instruments for particle sizing and gradation testing.
