Product data sheets are a valuable tool for coating applicators as well as trained and certified coating inspectors. They are essentially an instruction manual for using the product. Unfortunately, many of us don’t read the instructions until it is too late.
In the case of CSP and intumescent systems, if they are not applied to the correct thickness across all surfaces of load-bearing steel members or panels/plates and there is a fire event, catastrophic collapse due to heat transfer to the steel can occur resulting in potential loss of life.
Testing of new and recycled abrasive is an important, yet frequently overlooked inspection checkpoint. Abrasive cleanliness is an indirect or referenced requirement for each of the joint SSPC/NACE abrasive blast cleaning surface cleanliness standards.
Instruments that are used to verify quality must be calibrated and verified for accuracy, when feasible. Instrumentation is calibrated by the equipment manufacturer or an accredited calibration laboratory, while the instrument user is responsible for verifying accuracy.
