This International Standard applies to air driven powder jet handpieces and their associated powders for use in the field of dentistry on patients to remove dental debris, discolourations and plaque and to clean and polish teeths where abrasion is a side effect. It is also applicable to air driven powder jet handpieces and their associated powders that are used in dentistry for air driven abrasion, e.g. minimally invasive cavity preparation, preparation of surfaces for adhesives and for the removal of cement residues where abrasion is part of the desired outcome. This standard defines the general requirements, test methods, manufacturer's information, marking and packaging, independently of the design of the air driven powder jet handpiece. This standard is not applicable for the dental units that are employed to supply the powder jet handpieces, regardless if these dental units are floor fixed, mobile or table top units. This standard is not applicable to dental prophylaxis handpieces (contra angles), air driven or electrically driven plaque removers (scalers) or multifunctional handpieces (syringes)
