Fabrication and service history Sample Clauses

Fabrication and service history. This subsection of the ASTM manual states that “Fabrication and service history fields contain information on the joining, machining, or shaping technique employed on the part, plus applicable service experience.”. A class that is described in this way is a class of engineering material defined by fabrication and service history, meaning a class of engineering material where the criteria for membership are one or more of:  the joining, machining, or shaping technique employed on the part  the service history of the part NOTE Division between post-processing and fabrication is not precise and depends on the organization that carries out the activity rather than upon the nature of the activity. Consequently, two subclasses of fabrication and service history, corresponding to fabrication, and to service history, can be defined, as follows:  class of engineering material defined by fabrication, meaning a class of engineering material where the criteria for membership are one or more of the joining, machining, or shaping technique employed on the part  class of engineering material defined service history, meaning a class of engineering material where the criterion for membership is the service history of the part Some service history is concerned with engineering material interactions, which can be chemical interactions, including corrosion and environmental. Thus, a further subclass can be defined as follows:  class of engineering material defined by service interaction, meaning a class of engineering material where the criteria for membership are the interactions with other materials that occur during service
