Why checking the powder

Checking powder means to make sure that no foreign body is being carried with the powder, either at the beginning of the process (powder bought from a supplier) or at the end of the process (prior to delivery to the customer or packaging).

Foreign bodies can damage process equipments, significantly increases the ATEX risk, and can ultimately be carried to the customers where claims are then likely.
