ISO 11127-5 is part of the test method for non-metallic abrasive for surface preparation sand blasting cleaning of steel before painting. This part is the determination of moisture. The standard specifies the method for determining the non-metallic abrasive Moisture content to ensure the mass and adaptability of the abrasive. The standard specifies the experimental equipment, experimental procedures and data processing methods. Specifically, the standard requires that abrasive samples be tested at a specific temperature and time, and then the Moisture content of the abrasive is calculated. The standard also specifies the accuracy and Reliability requirements for the determination, and the manner in which the test results are reported.
