In brief
Pressure is one part of a dispensing system; this article helps teams prepare observable questions when comparing samples.
How should pressure be considered when comparing a sample?
Pressure is discussed as part of the aerosol system, so the question is how it relates to the use conditions and the sample being compared.
- Use conditions
- System context
- Reference sample
Which observations make a sample comparison useful?
A useful comparison records the observations agreed for the same sample basis instead of drawing a conclusion from one isolated feature.
- Shared basis
- Observed result
- Comparison notes
What should be recorded?
Keep the sample identity, the stated conditions and the observations together so a later discussion can return to the same record.
- Sample identity
- Conditions
- Record
