In this draft a hierarchical structure of the cleaning processes alongside the impact principle is proposed. Hierarchical levels are represented by a multi digit number. The next hierarchical level of the classification scheme states the physical impact principle of the cleaning processes.
EN ISO 12944-5_1998_inloc DIN 55928-5
Therefore the blasting processes were put into a special subgroup. Draft DIN neither dij processes which combine several physical impact principles nor can newly developed special processes be integrated into the scheme.
Also ddin proposed gradation is not detailed enough to clearly differentiate single processes from one another. Standards providing clear guidance for the actual cleaning exist only for a limited number of processes.
Only processes which have been applied for a long time have been standardized like: In recent years mainly in USA newly developed processes have not been introduced into European standards.
Degrees of ddin, which can be achieved by the single cleaning processes have only be standardized in very limited cases, e. However these approaches cannot djn such be applied to other cases. As concerns the area of cleaning equipment mainly the safety aspects of this machinery shall be standardized without referring to utilization and application limits of the described equipment pr EN Summarizing it has to be noted, that the German and European standardization only give limited assistance when trying to select a specific cleaning process according to the actual workshop requirements.
A classification of the degree of soiling or cleanliness is not provided by the German 55982 European standards. Only for surface preparation degrees for steel structures there is an existing standard DIN But this definition cannot be applied in general to the cleaning of components. The US American standards give at least approaches to the definition of degrees of cleanliness and related cleaning methods.
The American ASTM American Society for Testing and Materials lays down compulsory test methods in many areas, which are meant to dinn the fitness of a cleaning procedure for a given purpose.
In most cases not the cleanliness of xin component is tested but rather as to whether the subsequent process e. A quantitative cleanliness standard is applied at the US military: The American military standard MIL-STD C contains an approach relating to the amount 559928 soiling of a given type on a defined surface area or in a defined volume. The units depend on the type of dirts e.
The test methods for the determination of the degree of dim are compulsory. This standard and the related degrees of cleanliness are based on very high requirements as they are needed for, among others, aeronautics. To apply these standards in ordinary manufacturing cannot be recommended because of the necessary expensive test methods. Home Parts cleaning Standards.
