Recommendations
• It is recommended that wherever
possible ISO standard symbols with
text be used rather than using the
Main
manufacturers’ ownDisplay
symbols. Where
the required symbol is not available
as a standard, the manufacturer
should seek to influence the ISO
standard to include a new symbol.
• Symbols need to be tested with
users in context. There is an ISO
standard for developing and
testing symbols with users.19
• It is recommended that manufacturers
Volume
add text labels to symbols
History until
the meaning of the symbols are
universally recognised by users.
• Symbol recognition and
understanding of function should
be incorporated into training and
competency assessment materials.
The on/off button should be the only
button with 2 functions. In line with
MHRA requirements, turning off the
pump should be a 2 step process
requiring confirmation from the user.
