Part 4: Basic quality requirements
This part of GB/T 19352 specifies quality requirements in such a way that it is independent of the type of thermally sprayed structure. - It defines the quality requirements for thermal spraying not only in the workshop but also on site. It provides guidance for describing the manufacturer's ability to produce thermally sprayed components that meet the specified requirements. It can also serve as a basis for assessing the manufacturer's thermal spraying capabilities. This part applies when the manufacturer's ability to produce thermally sprayed components to the promised quality requirements is detailed in one or more of the following documents:
- A contract signed by the parties concerned;
- Adopted standards,
Requirements of regulations.
The requirements in this part can be adopted in full; if the relevant component is not applicable, the manufacturer may selectively delete some of them. These requirements provide an adaptable framework for thermal spraying control in the following circumstances: - Situations -
When the contract requires When the manufacturer is required to have a quality system that complies with GB/T19001-1994 or GB/T19002--1994, the thermal spraying requirements in the contract shall be clearly provided.
Case 2
When the contract requires the manufacturer to establish a quality system, the thermal spraying requirements in the contract shall be clearly provided. Case 3
When the adopted standard includes thermal spraying as part of its requirements, the thermal spraying requirements in the adopted standard shall be clearly provided: or the thermal spraying requirements shall be clearly specified in the contract signed by the relevant parties. 2 Normative references
