GB/T 19352.3—2003/ISO 14922-3:1999 Thermal spraying Quality requirements for thermally sprayed structures
Part 3: Standard quality requirements
This part of GB/T 19352 specifies the quality requirements as follows: - It is independent of the type of thermally sprayed structure. - It defines not only the quality requirements for thermal spraying in the workshop, but also the quality requirements for thermal spraying on site. - It provides a guide to describe 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 according to the promised quality requirements is detailed in one or more of the following documents:
- A contract signed by the parties concerned;
Adopted standards;
Regulatory requirements.
The requirements in this part may be all Adopted; if the relevant components cannot be applied, the manufacturer may selectively delete a part. These requirements provide a flexible framework for thermal spray control in the following cases: Case
When the contract requires the manufacturer to have a quality system that complies with GB/T19001-1994 or GB/T19002-1994, clearly provide the thermal spraying requirements in the contract.
Case 2
When the contract requires the manufacturer to establish a quality system, clearly provide the thermal spraying requirements in the contract. Case 3
When the adopted standard includes thermal spraying as part of its requirements, clearly provide the thermal spraying requirements in the adopted standard; or clearly specify the thermal spraying requirements in the contract signed by the relevant parties. In this case, Part 4 of this standard may be more applicable.
