7.7 STSysQualityControlType ObjectType Definition

The STSysQualityControlType provides relevant variables and parameters for controlling and monitoring a quality control system, station or zone of a cleaning and pretreatment machine and is formally defined in Table 27.

Monitoring represents a collection of variables that are not assigned to a component but to the overall system.

Components is an add-in used to assign components (e.g. of STCompType) to the system.

The components of the STSysQualityControlType have additional subcomponents which are defined in Table 28.

ParticleCountClassXPart is a placeholder to represent the measured or calculated number of particles of a specified size class (Size Class X) extracted from a workpiece or part in relation to a reference area as specified by VDA 19/ISO 16232. This parameter can be re-used for each Size Class required for evaluation. Suggested unit: -.

ParticleCountClassXLiquid is a placeholder to represent the measured or calculated number of particles of a specified size class (Size Class X) in liquid of the rinsing or cleaning stage in relation to a reference volume as specified by VDA 19/ISO 16232. This parameter can be re-used for each Size Class required for evaluation. Suggested unit: -.

FluorescencePart represents the measured fluorescence intensity of the component surface in relation to excitation power as a measure of the part cleanliness level regarding organic contaminants (oils, cooling lubes, release agents). Typically an aggregated characteristic output e.g. an average of multiple points sampled across the surface or functional areas. Suggested unit: - or RFU (relative fluorescence units).

QualityIndexPart represents the calculated Index Score of the quality-determining parameters of the components. Suggested unit: -.

ParticleWeightPart describes the particle fraction of the components determined by wash extraction in accordance with VDA 19/ISO 16232 in relation to a reference surface. Suggested unit: mg/cm².

NonVolatileResidualsPart describes the proportion of non-volatile components on the part in relation to a reference surface. Suggested unit: mg/m².

ResidualGasAnalysisWater describes the outgassing rate of water with atomic mass unit 18 remaining in a vacuum system. Suggested unit: mbar*l/s.

ResidualGasAnalysisLightHydrocarbons describes the outgassing rate of high-volatility hydrocarbons with atomic mass unit 45 - 100 remaining in a vacuum system. Suggested unit: mbar*l/s.

ResidualGasAnalysisHeavyHydrocarbons describes the outgassing rate of low-volatility hydrocarbons with atomic mass unit 101 - 200 remaining in a vacuum system. Suggested unit: mbar*l/s.
