This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 334.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which
stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other language
made by translation under the responsibility of a CEN member into its own language and notified to the Management Centre has the same
status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,

1 Scope
This standard specifies the hydraulic and mechanical features necessary for defining the functioning of the
emitting devices, whether or not equipped with compensating features, designed for use in localised irrigation
systems.
The manner in which the manufacturers shall provide the basic engineering information for the design and use
of the localised irrigation systems and the appropriate testing methods for checking and assuring the proper
working order thereof are specified.
This standard applies to all the emitting devices listed in EN 13635:2001, 3.1, with the following restrictions:
- Micro-sprinklers, micro-sprayers or micro-jets are dealt with solely as components which aim is to wet a
predetermined restricted area
- Porous pipes are not included under this standard as a result of deeming the hydraulic features thereof
to differ from the rest of the emitting devices.
- Other devices such as misters, the essential function of which is that of creating a moist atmosphere
more than watering as such, are not included.

2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 13635:2001 apply.
4 Classification
For the purposes of the tests to be conducted, the emitting devices which are to be included under this
standard are classified as follows
a) Drip devices

b) Emitting pipes and tapes
c) Sprayers
d) Micro sprinklers
5 General requirements
5.1 Materials
The plastic materials that are exposed to light shall be opaque and UV resistant.
Plastics, rubber and metal parts shall be as much as possible corrosion-resistant, abrasion-resistant and
resistant to ageing.
In all cases, to the extent possible, neither algae nor bacteria shall be allowed to build up in the system, and
its parts shall withstand waters containing chemicals commonly used in agriculture and wastewater.
The manufacturer shall provide information regarding any restriction.
5.2 Manufacture and assembly
The emitting devices shall have no manufacturing defect whatsoever which might be detrimental to the
operating features thereof.
They shall be features providing easy fitting and assembly. All those equipped with removable parts shall be
easy to operate manually or using common tools. Should any special tool be required, the manufacturer shall
furnish the same. The removable parts of one same type and one same make shall be interchangeable.
5.3 Connections
When polyethylene (PE) pipe is used, in-line emitting devices or insert-type fittings shall not increase the pipe
diameter by more than 13%.
In those cases in which threaded connections of emitting devices are used to fit with other standardised
elements, the threading shall adhere to the specific international standard, or to ISO 7-1, and the number of
thread turns used for the assembly shall be three or more (as specified in ISO 8026).
6 Design feature tests
6.1 Visual Aspects
The new emitting devices as a whole and each one of the parts thereof into which they can be disassembled
shall not have any cracks, holes or pores. Nor shall it be admissible for them to have any scratches, any
ridges or any other visible manufacturing defect which might lessen their performance, useful life, operation or
proper installation.
The check of visual aspects shall be conducted on a minimum of 25 emitting devices selected at random from
a batch of at least 500 emitting devices.
