Bias Testing - Sampler Inspections
Vanguard Solutions has over 25 years experience in the design, performance and evaluation of mechanical coal sampling systems. We can provide an inspection, a bias test or maintain a schedule that performs inspections and bias tests on regular intervals.
ASTM and ISO recommend that mechanical sampling systems should be tested periodically. Call us and we will tell you how to calculate whether it is time to bias test your system. If you don't need a test, we will tell you and send you documentation for your Sarbanes-Oxley file.
Tests and inspections have been performed on all types of systems in a variety of situations. Our experience has given us the advantage to design tests that result in less strain on coal loading and unloading systems, less site time, lower costs and more rapid turnaround of results.
