The Handheld Spray Nozzle IPX3 IPX4 verifies the waterproof status of the product’s enclosures of larger sizes when a portable tester is necessary. INNOVATION Dunel research department brings to the market the lightest hand-held spray nozzle, built with a resistant material. Furthermore, it presents an ergonomic design that provides easiness during the performance of the tests in Lab. All these innovations maintain the accuracy required by the International Norms. The test equipment comes with a Flow Bowl Valve for setting the flow of water requested by the Norm. Another essential accessory for this tester performance is the Flow Meter System that Dunel can provide under request. We are co

FOUR POINTS YOU NEED TO CONSIDER: IEC 60529 Drip Box IPX1 IPX2 - Tips Guarantee that when cleaning the nozzles they do not lose dimensionally. The one’s plastic made, nozzles molded together with manifold, can have sizes modified due to cleaning process and change of environmental temperature IPX1 BEST PERFORMANCE That the manifold can support high water pressure over 5 bar. Plastic made in some cases do not support. That the manifold does not crack after some time of use. Plastic can crack. Guarantee of the 20mm x 20mm dimensional spacing between the nozzles, required by the Standards. Hypodermic Needles or Tubes of Ink Pens do not guarantee it! PROTECT YOUR INVESTMENT!

Tracking Surface is the propagation of an electrically conductive path along the surface of an electrical insulator due to the breakdown of the insulation material. The tracking test simulates the electrical propagation over the surface under test. It is commonly used to verify the resistance of the insulation materials. Tracking develops from surface discharge activity associated with the flow of leakage current, especially under wet or contaminated conditions. Arcs created from surface discharges burn the insulating material and create electrically conductive carbonized tracks, reducing or eliminating the insulation properties of the material under test.

Table. I – IP Code – Ingress Protection of Solid objects Short Description & IP Code Application Tips 0 = Not Protected IP1X = Protected against ingress of solid objects of Ø 50 mm and bigger – Use Handled Sphere Probe IP2X = Protected against ingress of solid objects Ø 12 mm and bigger – Use Jointed Finger Probe IP3X = Protected against ingress of solid objects Ø 2,5 mm and bigger – Use Rode Wire Probe Ø 2,5 mm IP4X = Protected against ingress of solid objects Ø 1,0 mm and bigger – Use Rode Wire Probe Ø 1,0 mm IP5X = Protected against dust/powder – e.g. – Use Dust Chamber Without Vacuum – Use Dust Chamber Tester IP6X = Fully protected against dust/powder – e.g. – Use Dust C

Oscillating tubes DNOT Series with spray nozzles of 0,4mm bore are used to prove the degrees of protection IPX3 &IPX4 – Protection Against Spraying Water” & “Protection Against Splashing Water”. The protection against spraying water is determined by causing the oscillating tube to oscillate over the specimen through an angle of 60° Degrees on either side of the vertical, each at a speed of about of 60° per second, while the jets, coming from a larger angle than 60° to the vertical, are baffled by deflectors. But there is also a slightly amended regulation, (sai fora according to pq nao explica a que ) which the oscillating tube with deflectors stands still in a vertical position, and the
