The above graduations are only typical. Normal production tolerances from the typical will be permitted. A trace is allowable on the next coarser sieve.

Test Method: Split sample to 50 grams and shake for 10-20 minutes on Ro-Tap type sieve shaker. Use standard 8-inch U.S. Mesh testing sieves.

 

 

Here at Hess Pumice we are continuously testing our product to insure superior quality. Among the most common tests that we perform in-house are:

• Sieve Size Analysis (ASTM C-136)
• Particle Size Analysis by Laser Diffraction (Coulter Method)
• Whiteness (Datacolor “Check” method)

We also submit product samples to outside laboratories for third-party verification in the following areas:

• Bacteria plate count
• Chemical analysis
• Bulk Density

We adhere to a strict inspection policy and are compliant with all ISO 9000/2000 standards.

Every lot of product is tested a minimum of three times during the production process with samples being retained for at least two years. All quality and sales records are retained electronically as well as in hard-copy form.

We go to great lengths to ensure customer satisfaction in both our product and the entire purchasing experience.
