Check Sample Program

The ASTA Check Sample Program aims to strengthen laboratory credibility and promote high levels of accuracy within and among laboratories using standard analytical test methods for spices and herbs. The methods, such as ASTA’s Official Analytical Methods, provide a uniform way to measure results within and among laboratories. The program is designed to evaluate spice laboratories for a common range of analyses and spices significant to the spice trade. It allows individual laboratories to evaluate their performance and set goals for improvement and consistency in analyses.
