Pressure directive
1
Sound Engineering Practice (SEP) as defined in the Pressure Equipment Directive (PED)
1 Applies to products with CE marks. For information on products without CE marks, contact your
nearest YOKOGAWA dealer.
2 The overvoltage category (installation category) is a value used to define the transient overvoltage
condition and includes the rated impulse withstand voltage. The overvoltage category II applies to
electrical equipment that is powered through a fixed installation, such as a switchboard.
3 Pollution Degree applies to the degree of adhesion of a solid, liquid, or gas that deteriorates
withstand voltage or surface resistivity. Pollution degree 2 applies to normal indoor atmospheres (with
only non-conductive pollution).
4 The measurement category of the instrument signal terminals is Other (O). Do not use it to measure
the main power supply or for Measurement Categories II, III, or IV.
Measurement category O (Other) applies to measurement of circuits that are not directly connected
to a main power supply. This category applies to measurement of secondary electric circuits in
equipment across a transformer. The estimated transient overvoltage that may appear at the
instrument’s signal input is 350 V.
Measurement category II applies to measurement of circuits, such as household electric appliances
and portable electric tools, that are connected to low-voltage installations.
Measurement category III applies to measurement of facility circuits, such as distribution boards
and circuit breakers.
Measurement category IV applies to measurement of power source circuits, such as entrance
cables to buildings and cable systems, for low-voltage installations.
