Specifications of Light-weight Emergency Tent
Version
4.0: June 2006
1. Background
1a. Two main items used by UNHCR to provide shelter in an emergency situations have been plastic sheeting
and canvas tents. They both have their advantages and disadvantages.
1b. Plastic sheeting though light in weight, hardly provides a solution to shelter and canvas tents though with a
lower cost, they are very heavy, have limited shelf life and costly to transport.
1c. In continuation of UNHCR’s on-going efforts to improve preparedness for emergencies, the relevant sections in
UNHCR began the process of developing a Light-weight Emergency Tent (LWET).
1d. With the set criteria such as lightweight, longer shelf life and durability, UNHCR embarked on
development of such a tent using different type material, different type of poles and a different shape.
1e. The work was carried out by benefiting from both Geneva and field based review.
1f. The following pages are result of a joint efforts within UNHCR, which is presented in text specifications of
the developed tent along with the related pictures. It is important to mention the following two points:
ƒ
ƒ
Weight of this tent is 41.5 Kg (including steel pegs, a hammer and packaging) and packed in a hand
bag for the ease of handling, it maybe noted that UNHCR traditional canvas tents of 4.00m x 4.00m, the
ridge type is 80.0 kg and centre pole tent is 110.0 kg with the same floor area but more living space.
In addition to the its lightweight and long shelf life, this tent has two separate doors at each end, is
fully mosquito proof and is easy to pitch. The tent has a partition dividing it into two separate space to
ensure privacy and dignity. This is maybe the first time that a family tent has partitioning.
1g. Great attention has been given to the details for providing a suitable solution hence production of tent
requires best possible craftsmanship in line with craftsmanship of leisure tents.

2. Shape, Size and Construction
2a. The tent is semi-circular or tunnel shaped with centre height of 210 cm, width of 300 cm and length of
550 cm.
2b. It consists of two full layers or double fly i.e. a water proof outer shell and an inner tent with 12 cm
continuous distance between them.
2c. The size/total useable floor area of the outer shell is (3.00 m x 5.50 m) 16.50 m2 sufficient for a family
of 4-5 persons at the rate of 3.5 m2 sleeping area per person.

4.0: June 2006
2d. The inner tent, which is with integrated flooring (“bathtub” ground sheeting), is supported by or hung
from the outer shell. However when occupied, the inner tent acts as stabilizer of the outer shell and hence
provides greater stability to the tent itself.
2e. The outer shell acts as a pure “shell” and not a “tent” and hence with no mud flap which in turn reduces
the cost, weight and increases the durability of tent.

3. The outer shell (Specifications)
3a. Woven polyester of Ripstop weave with number count of wrap 64 and weft 42 threads per inch.
3b. Basic weight 150 -170 grams / m2.
3c. The outer shell is of white colour from both sides.
3d. Free of weaving defects that would have a negative affect on strength, water profess and durability.
3e. Water proof to withstand a minimum of 3000 mm of static water column, subject to testing.
3f. Fabric should be stabilised against decomposition (termite,
mold, mildew and rot).
3g. Stabilised against UV degradation for 2,000 hours, subject to
testing.
3h.
Fire retardant coating to reduce flammability by either
polyurethane or aluminium coating or others in accordance with
CPAI-84 1955 standards.
3i. Integrated and continuous Sleeves (5 sleeves or loops) with no
breaks (for the ease of rod insertion) to house the tension rods
for holding the outer shell from which the inner tent would be
suspended. The width of sleeve should be large enough for
inserting the rods easily but not too large to allow unnecessary
movement of rod within the sleeve.

3j.
4.0: June 2006
All seams to be double locked stitched, and supported with anti-leak/anti-seepage water taping.
The supplier will insure that the stitch count and thread used for all parts of the tent are appropriate for the
material and will produce strong, long lasting (both on the shelf and in use) and are of highest degree of
craftsmanship. Low quality workmanship at any point
is categorically unacceptable.
3k. Strong and rot proof ground fixation at 10 specified
locations at the ends of sleeves around the perimeter of the
tent (5 on each side). The fixation ends with a metallic
triangle as shown in the picture. End of rods will be inserted
in the hole and fixed to the ground.
3l.
The outer shell should have 10 triangular reinforcement as shown in the picture at each fixation point to
prevent tearing of the material. The reinforcement triangle is about 15 cm on the sides and 25 cm on the
bottom with the same material of outer shell.

3m. A strap with width of 38 mm and strength to carrying 100
Kg of load, rot proof equipped with a metallic triangle as
shown in the picture and a metallic buckle near one side of
the tension rod to hold the both ends of tension rod at a
distance of 3.00 meters from one another. We have provided
two pictures on the way this should be done.
3n. The outer shell at each end of the tension rods should be fixed
to the strap in order to avoid roll-up of outer shell along the
tension rod.

Version
4.0: June 2006
3o. Four integrated windows size 40cm x 30 cm (two on each long sides) with mosquito nets of minimum
aperture, (for outer shell, B18 which is used for its strength and ventilation and for inner tent, B4 for
preventing mosquitoes to pass through) and fully covered flap equipped with Velcro all around the perimeter.
The windows should be able to be rolled up and fixed up with buttons. The mosquito net for the inner tent
(doors, windows and ventilations openings) and outer shell should be long lasting insecticide treated in
accordance with WHO standards.
WHO recommended insecticides for treatment of mosquito nets for malaria vector control.

3q. There are six side ropes (three
on each side of the tent). The
connecting mechanism of the
side ropes to the outer shell
should be double fold in
triangular shape with the
same material as outer shell,
with a base of about 22 cm
and sides of about 21 and 11
cm connected to both sides
of the sleeve holding the
tension rods reinforced in the
end of about 4 cm wide and
equipped with
webbing to
knot the side rope.
The
location of this triangle is
approximately 125 cm from
the ground level to the centre
of the triangle. It is important
the connection envelopes the
tension
rod
so
as
he
distribution the tension force
of the rope transmitted to the
to the pole and not the fabric.

Specifications of Light-weight Emergency Tent
Version
4.0: June 2006
3r. There are eight connections for
the guy ropes (four at either
end
of
the
tent).
These
connections should be stronger
than the side ones as they take
more
pressure
and
are
important to keep the tent
straight. We have therefore
provided a different mechanism
than the side connections.
They are made of double
webbing stitched to the either
side of the sleeve. The outer
shell at the place of stitch is
reinforced by a triangle of 16cm
x16cm x 16cm. The connecting
mechanism of the guy ropes
(ropes on either end of tent) is
a handle system in which two
pieces of strong webbing of
4 cm wide in white colour as
per details of the drawing
are used. The connection
mechanism for the lower guy
rope is about 115 cm in line
with the connection of side ropes and the upper one about 180 cm from the ground along the sleeve. Please
see the next page for the pictures of this system.

Double white coloured webbing with
reinforcement as described in the above paragraph
under (3r).

3s. The outer shell should have a connecting mechanism under each tension rod 25 cm apart from each other so
that the inner shell can be
hanged from it. Both the
outer shell and the inner
tent should be with be
equipped
with
this
connecting
mechanism
(webbing and rust proof
metallic ring from the outer
shell and strap from the
outer tent material and
toggle from the inner tent)
at every 25 cm to be hung
from the outer shell from all
5 tension rods. One single
mechanism should be strong
enough to carry or withstand
a weight of about 10kg.
Webbing and tent material
as shown in the picture
should be the only connector
fabrics used. Care should be
exercised that the stitches
are
strong
enough
to
withstand the load.

3t. One chimney outlet of 12 cm in diameter made of a special
fire resistant fabric (apron) to with stand heat up to 500
degree centigrade.
3u. The hole should be able to be closed tightly to avoid rain and
moisture infiltration when heating of the tent is not required.
3v. The outlet should be wider towards the bottom to reach a
diameter of 30 cm where it will be stitched to the tent. It
would be located in the fourth section (fourth out of four
sections) ¾ from the end of tent and located on the side of
the tent. The centre of the hole would be about 155 cm
from the ground covered with the same material of
outer shell covered 60cm X 60cm equipped with Velcro
similar to the way windows are covered. This is to
prevent any water infiltration when stove is not used. The
seam on the upper part should be treated with water sealant
as other seams. The outlet will also have removable cover
from the inner tent.

Integrated strong ground sheeting made of polyethylene,
weight: 200 gram/ m2, water proof to withstand 2000
mm of water column and double stitched to inner tent.
The stitching of the ground sheet to the inner tent should be
about 20cm above the ground to ensure better resistance
to possible water infiltration. All seams should be treated
with anti-leak/anti-seepage water sealant/tape.
4m. The ground sheeting shall be of dark blue in colour so as
not to stain easily after some usage and same as UNHCR
specified plastic tarpaulin that has proven best for such
usage. It is made of woven high density polyethylene
fibbers; warp x weft: 12/14 x 12/14 per square inch,
laminated on both sides with low density polyethylene;
Material weight: minimum 200 gr/m2 +/- 5%; Tensile

4n. Inner tent shall be supported by the outer shell (hung from the outer shell). All rings shall be of rust
resistance material.
4o. The inner shell should have a
connecting mechanism under each
tension rod 25 cm apart from each
other so that the inner shell can be
hanged from the outer shell. Both
the outer shell and the inner tent
should be equipped with this
connecting mechanism ( webbing
and rust proof metallic ring from
the outer shell and strap from outer
tent material and toggle from the
inner tent) at every 25 cm to be
hung from the outer shell from all
5 tension rods. One single
mechanism
should
be
strong
enough to carry or withstand a
weight of about 10kg. Webbing
and tent material as shown in the
picture
should
be
the
only
connector fabrics used. Care should
be exercised that the stitches are
strong enough to withstand the
load.

4p. Distance between the outer shell and the inner tent shall be
12 cm minimum. This is important as it has direct effect
on the heat transfer, hence the distance should not be less
than 12 cm that has been prescribed,
The connection of the four corners close to the
ground will have the adjustable buckle as shown
in the picture

4s. The inner tent should be partitioned in the middle dividing
the tent into two sections of 2.75m X 2.76m = 7.59 m2,
4t. The partitioning consists of two sections, which will be
stitched to the inner tent with about 40 cm overlapping in
the middle equipped with buttons. The partition can be
rolled back to the sides with tie strap to hold it on both
sides of the tent. The material would be the same as inner
tent, and must not be of transparent material.

4u. The inner tent will have a canopy of about 150 cm stitched
across the top and coming out from the tent a distance
of 100 cm on the both ends of the inner tent. The canopy
which is of the same material as the outer tent, is stitched to
the upper ends of the inner tent equipped with two guy
ropes that connect its two outer corners to the existing pegs,
4v. A pocket of clear plastic for inserting an A4 paper in the
landscape way to be fixed to both ends of the inner tent on
the left side of the door. This should be close to the
edge of the tent and 1.00 m from the ground taped
with water sealing tape.

Version
4.0: June 2006
5. Support System / Tension Rods (Specifications)
5a.
Tension rods should be of solid fibre glass reinforced
with black polyethylene wrapper, with in odd number
of tubular sleeves or internal rod connector pins to provide
with the desired length, shape and a standing free height of
210 cm at the centre of the tent. The rod diameter to be of
15 mm (12.4 mm fibreglass and with wrapper 15.36
mm in diameter).
5b.
There will be five tension rods of 5a above dividing the
tent into four equal segments. The tension rods should
be divided into odd number.
5c. The rods should be “shock-corded” (having a cord inside the rod). The joints shall be easy to assemble and
should be sufficiently reinforced to avoid any possible breakage as these are the weak points in the
tension rods.
Page 26 of 36
Specifications of Light-weight Emergency Tent
Version
4.0: June 2006
5d. The ends of the tension rods are anchored to the ground with an aluminium or bras eyelet in the strap
connecting the both sides of
tension rod in place,
5e. The metallic
ends
of the
tension rods should be at least
5.0 cm long at each end to
ensure better fixation of the
frame to the strap and to the
ground,
5f. One extra rod should be
included in every tent. This
is to offset any undetected
weakness or defect that the
rods may have.

Specifications of Light-weight Emergency Tent
Version
4.0: June 2006
6. Side and Guy Ropes (Specifications)
6a.
Guy ropes should be made of polypropylene fibres in three
strands, having a diameter of 06 mm and length of 3.00
meters for the side ropes and four guy ropes and 3.5
meters for the other four guy ropes that are attached to the
upper part of either end of the tent,
6b. The strength of the guy ropes should not be less than 50 Kg,
6c. Guy ropes should be UV resistance,
6d. Four guy ropes on each end and three on each long side
of the outer shell hence gives total of 14 guy and side
ropes. All ropes are equipped with a simple and light
tightening mechanism. This should be either of a light
metallic or a varnished wooden nature. It should be noted
that there is provision of one peg for two guy ropes and one
for each side ropes hence total 10 pegs.
6e. Guy and side ropes should be pre-knotted to the outer tent.
This will facilitate installation of the tent in the field and
prevents removal of the ropes during the installation of tent.

Specifications of Light-weight Emergency Tent
Version
4.0: June 2006
7. Pegs (Specifications)
7a.
Pegs for the outer shell shall be of corrugated (deformed)
steel having a length 30 cm ,including the bend and,
diameter 12 mm, with provision of a smooth “U” shaped
bend to hook and tie up the guy ropes and tapered in the
other end. Our experience has shown that the aluminium
pegs in real refugee situation do not perform as desired
hence we need to compromise weight for practical
performance i.e. to use iron pegs,
7b. Total of 10 corrugated pegs for outer shell are required. The
corrugation will increase the shear force resistance. The pegs
are tapered at one end to ensure easy anchoring into the
ground,
7c. It may be noted that in this design we have eliminated pegs
for inner tent.
7d.
A hammer strong enough for hammering the pegs

8a. The procedure of erection of tent
should be clearly and thoroughly
written in a step by step manner and
shown using drawings or pictures to be
packed individually in each tent,
8b. Markings to be printed in blue indelible
ink on both sides of the tent and on the top of the tent (to be positioned horizontally) for maximum
visibility. The width of marking would be 120cm and the height proportionate to the width without any
distortion of the logo and letterings (approximately 35cm).
8c. Both the outer shell and inner tents shall be treated with a fire retardant chemicals.
8d. Inspection will take place in accordance to Para 18 of “Doing business with UNHCR dated November 2002”,
8e. The outer shell, the inner tent and all the accessories shall be packed in one single bag made out of the
outer shell material with a carrying handle (Pic 1 and 2). The bag will be in a strong transparent
polyethylene (Pic 3) and covered with Polyethylene bag Pic 4 . It will have two plastic straps (Pic 4)
to hold it together. Please see the related pictures.
8g. The craftsmanship on this product needs to be of highest quality and tolerances
carefully taken into consideration for maximum performance.
These specifications will be in effect for at least two years and any changes by any entitity, even for
their own use, requires prior consultation and approval of UNHCR in order to uphold the integrity
of the original concept and design of this well received product
