4.2.5 There shall be no damage on load-bearing straps and their fixation points that reduces their
functionality as a consequence of the specified strap drop test.
Compliance shall be tested according to ISO 19932-2:2025, 5.3.3.
4.3 Spray tank
4.3.1 The nominal volume shall be specified in whole litres (l). It shall be possible to determine the spray
tank filling level of the sprayer with a minimum resolution of 1 l. If the nominal volume of the sprayer is at
least 10 l, it is accepted to have the first marking at maximum 20 % of the nominal volume.
Compliance shall be checked by inspection.
4.3.2 The volumetric contents gauge scale shall have a maximum error of the reading of ±10 % up to a
filling level of 5 l and ±5 % above.
Compliance shall be tested according to ISO 19932-2:2025, 5.3.5.
4.3.3 It shall be possible to fill the spray tank to its nominal volume within 60 s. The total volume of all
liquid spillage during filling shall not exceed 5 ml.
Compliance shall be tested according to ISO 19932-2:2025, 5.3.6.
4.3.4 It shall be possible to fully empty the spray tank. The amount of liquid remaining in the spray tank
shall not exceed 50 g.
Compliance shall be tested according to ISO 19932-2:2025, 5.3.7.
4.3.5 The operator shall be protected from coming into contact with the plant protection product when
emptying the spray tank. Emptying shall be possible without the use of a tool while wearing appropriate
protective gloves and with the flow being directed away from the operator so that it can be collected in a
suitable container.
Compliance shall be checked by inspection and function test.
4.4 Controls
4.4.1 It shall be possible to operate all controls by an operator wearing appropriate protective gloves.
Compliance shall be checked by inspection and function test.
4.4.2 The pressure line shall be equipped with a quick-acting shut-off device positioned so that it can be
easily reached by the operator in normal operating position. Unintentional opening of the shut-off device
shall be minimized by the application of a force, for example by means of a spring or a locking device. If the
device is lockable in the open position, it shall be locked by two independent and dissimilar actions and shall
be unlocked easily by one action. After unlocking, the device shall shut-off automatically when released.
Compliance shall be checked by inspection and function test.

ISO 19932-1:2025(en)
4.4.3 Any mechanical shut-off device shall be designed to work reliably. It shall properly open and close, it
shall not leak after 25 000 duty cycles.
Compliance shall be tested according to ISO 19932-2:2025, 5.3.1.
4.4.4 Sprayers shall have technical means to control and adjust the application rate of the sprayer. This
requirement is fulfilled for example, if the sprayer has a device for pressure control (pressure regulator) set
at a pre-determined value, a pressure indicator, etc.
If the device for pressure control is changeable or adjustable, it shall be possible without contamination of
the operator or environment. If the spray pressure is adjustable, the sprayer manufacturer shall provide
information on application rate at certain pressure settings. If the sprayer is fitted with a pressure indicator,
it shall be clearly readable and visible when the sprayer is being operated. Pressure indication shall be
stable. The resolution of indication shall be 20 kPa (0,2 bar). The error of indication shall not exceed 2,5 % of
the full scale value.
Compliance shall be checked by inspection and function test.
4.5 Hoses
4.5.1 The length of the hose shall allow safe, comfortable and ergonomic operation of the spray lance.
