You've hit the nail on the head with that NEN document. If "pers-" refers to the fact that it's for a compressed air hose, the translation indeed needs to be different.

Emma Rault (X) (asker) Jul 22, 2014:

I wasn't given that context (it's literally just a product description), but from the mention of the product standards and the fact that it's about a Storz connector it would seem that it is, yes.

Michael Beijer Jul 22, 2014:

@Emma: Incidentally, I just read Alexander’s comment (‘Where is there a 'delivery hose' mentioned in the original Dutch term?’), and all of a sudden thought I should ask you: is your text about firefighting? I just assumed it was, from your two references.

Michael Beijer Jul 22, 2014:

@Emma: See this document on the NEN website:

Title: ‘Brandweermaterieel – Watervoerende armaturen

Fire fighting equipment
Fire hose couplings and ancillary equipment’

http://www.nen.nl/pdfpreview/preview_7146.pdf

‘Benaming: Perskoppeling van 52 mm met kort slangstuk
Omschrijving: Koppeling met een kort slangstuk voor een persslang met een nominale middellijn van 52 mm
Aanduiding: Perskoppeling К - 52 - NEN 3374’

I also just found this in the GWIT:

persslang = delivery hose; compressed air hose
persslangkoppeling = delivery hose coupling
persleiding = pressure line; pressure pipe; force pipe; high-pressure line

See also the discussion here about different fittings here: http://www.klusidee.nl/Forum/about83017.html

Emma Rault (X) (asker) Jul 22, 2014:

While I certainly appreciate your elaborate research(!), all this is taking us further and further away from the original term. . . I do think "pers-" is about pressing something on, given that perskoppeling, persverbinding etc. are used in a variety of contexts. . . And that PDF I linked to in my last message explains in detail how it works.

‘quick connection couplings’ ‘Quick Connection Couplings Storz System for Liquids, Powders and Granulates

Symmetrical quick connection coupling, no female and male part, no problem with matching hose ends. Assembly and functionality of couplings Storz System.
Quick connection couplings with DS suffix generally are suitable for delivery and suction operation, without DS suffix for delivery operation only.
Working pressure is PN 16 if not mentioned otherwise.’ (http://www.awg-fittings.com/static_products/Quick_Connection... )

‘Instantaneous Fire Hose Couplings’ ‘Instantaneous Fire Hose Couplings are commonly used by the British Fire brigade for the delivery of water to firefighting systems but are sometimes used as an industrial hose coupling. They have a 2½" nominal bore head (either male or a female) and terminate in a variety of sizes of BSP female thread, BSP male thread and hose tails. They are available in light alloy and also gunmetal for corrosive environments such as marine or offshore use.

The female incorporates 2 spring loaded catches - a simple pull on both sides of the arms to release the adaptor. When connected, instantaneous fire hose couplings must be used for pressurised systems for the coupling to produce a leak free joint. The maximum working pressure for an instantaneous coupling is 15 bar.’

Michael Beijer Jul 22, 2014:

Storz I think it might also be sufficient to call it a

‘Storz Delivery Hose Coupling’

Still not sure about that ‘vaste’ part though

‘fixed Storz delivery hose coupling’?

See: http://en.wikipedia.org/wiki/Hose_coupling#Storz

Michael Beijer Jul 22, 2014:

¬¬¬ hmm, to be honest, I'm not sure whether ‘pers’ refers to pressing sth on, or to the fact that the pipes are under pressure. hopefully someone else here (with actual hands-on technical experience) will be able to enlighten us

I also found mention of so-called ‘instantaneous delivery hose couplings’

Emma Rault (X) (asker) Jul 22, 2014:

Yes, but it seems to me the "pers-" bit adds meaning I shouldn't leave out by just saying "hose coupling". It's "pers-" as in "press-fit", right? (Cf. http://www.euro-inox.org/pdf/map/PressFittingSystems_NL.pdf for elaborate description)

Michael Beijer Jul 22, 2014:

image I think it's the image to the left of the text:

‘3 inch metal pipe with a
Storz connection’

here:

http://www.brandweersxm.net/download/dry_stand_pipe_20070606...

...

i.e., the perskoppeling is the thing at the end, that the fire hose connects to.

Se also (‘delivery hose coupling’):

Michael Beijer Jul 22, 2014:

Hmm… I also found this in IATE:

perskoppeling = delivery hose coupling
def.: hose fitting for connecting delivery hoses

Definition Ref. INTERNATIONAL TECHNICAL FIRE SERVICE DICTIONARY

delivery hose coupling
Reliability 3 (Reliable)
Term Ref. INTERNATIONAL TECHNICAL FIRE SERVICE DICTIONARY

----------------

=> maybe sth like: ‘fixed delivery hose coupling’?

Emma Rault (X) (asker) Jul 22, 2014:

Hi Michael (appearing to the rescue as usual!). It's a product description of a Storz connector.

Michael Beijer Jul 22, 2014:

@Emma: Can we have some of your actual context?

See e.g.:

‘Dry pressure pipes:
• Pressure pipes must meet NEN 1594 standards.
•

(...)

• The pipe must be made of an inflammable material. The feed must be a fixed coupling
without sealing ring and with outside thread, as per NEN3374. The hose connectors on
all floors must be in accordance with DIN 14461, 2.5” Storz, as per NEN 3374,
armature CC. ’
