BS EN ISO 5912:2020 pdf free.Camping tents – Requirements and test methods.
Camping tents composed of an uncoated outer material shall be subjected to a pre-treatment process consisting of a single rain test and a subsequent drying period of a minimum of 24 h at ambient conditions.
NOTE It is recognized that due to local conditions and weather at the time of testing the drying period can be longer than 24 h.
8.3.3 Essential test requirements and test installation
The camping tent shall be tested on water permeable ground for example a lawn or synthetic turf surface with suitable drainage to avoid water pooling around the tent openings.
For water conservation purposes, water may be recycled, however care should be taken to ensure reused water does not contain any impurities which may block the spray system.
The water pressure shall be 300 kPa to 450 kPa, water shall be evenly sprinkled over the test area from a height of 4,5 m to 5 m above the ground. The water flow rate shall be a minimum of 60 I/h/rn2 over the test area. A pumped water system consisting of a ring main, or similar are acceptable to achieve the desired pressure, flow rate and evenness of application.
Sprinklers shall be designed to provide even and uniform coverage of the test area either by means of oscillation as in Figure 4 or by their position in a grid formation as in EigureS or other overhead manner.
NOTE A specific sprinkler hole’ size is not specified, as holes are not generally used to deliver the water from overhead sprinkler systems. Rain formation is usually in the form of a shower of droplets, not large drops, as long periods of medium rainfall are more likely to penetrate openings in use than heavy storms which tend to cause Ingress by poor drainage or badly located camping tents.
Test installations and equipment may be of varying designs providing the criteria detailed in L1 are met, it has been found that static installations with the side sprinklers as shown in Figure 4 are suitable, as are other designs which achieve the necessary key criteria. For example, test installations based on overhead sprinkler systems such as those used for building fire sprinkler systems see Figure 5.
In addition, suitable test installations may rely where necessary on manual rotation of the camping tent to ensure different entrances face the sprinkler systems, or on relocation of the sprinkler systems themselves, or an intermittent mechanical rotational system for the camping tent, or a fully automatic continual rotational system for the camping tent.
For large camping tents manual rotation of the camping tent itself to face different openings to sprinkler systems such as those in Figure 4 may be impractical due to the weight of the camping tent whilst wet and problems with correct re-erection, re-locating the sprinklers may be more practical.
Pitching of the camping tent shall be in accordance with manufacturer’s instructions, ventilation points shall be left open as instructed for use, and doors shall be closed for the duration of the test.All different types of entrances, ventilation points or openings shall be subjected to the rain test.
The water shall be applied in such a way as to fall onto both the roof area of the camping tent (including any ventilation openings) down the sides of the camping tent, and at least a minimum distance of 50 cm beyond the dimensions of the outer tent and any porch, or extension onto the ground (see Figure 4 and Figure 5).
If the test installation is designed such that the whole camping tent is tested at once (for example as in Figure 5 using an overhead spray system on a static or fully automatic rotational base), the complete test time shall be 30 min.
If the test installation is designed such that the camping tent can only be tested in sections such as in Figure 4 and the camping tent is to be rotated manually or in a semi-automatic fashion then the main entrance shall be tested facing sprinkler A in Figure 4 for 15 min, the camping tent shall then be rotated approximately 90° and tested for a further 15 min, thus a minimum of 30 min, and any additional entrances, ventilation points or openings of different designs shall also be tested facing sprinkler A in Figure 4 for 15 min each.
For fully automatic rotational test installations with rain being presented by side sprinklers rather than fully overhead sprinklers, the total test period shall be a minimum of 30 min plus an additional 15 min for each type of entrance, opening or ventilation point.Testing shall be carried out at ambient temperature.
NOTE It is recognized that the ambient temperature will vary due to location of test and time of year, however the volume of water and type of spray applied to the camping tent is the important parameter for this test.Following completion of the test, leave the camping tent for 2 min to allow excess water to drain from the vicinity of the doors before opening them to examine any ingress.The report shall include reference to any dampness or water on inner surfaces, pooling of water on the floor of the camping tent, or similar issues including location and severity.
For camping tents which are rotated manually to perform the test, inspection shall occur at the end of each 15 min increment in order that point of ingress can be correctly identified.
In addition, the type of installation used shall be described including details such as the manual rotation of the camping tent, relocation of the sprinkler systems, mechanical discontinuous rotational system,or fully automatic continual rotational system.
Lateral strength of zip fasteners
Lateral strength of the zip fastener
The velocity at which the clamps (see Figure 6) withdraw from each other is 15 cm/min. Prior to testing, the zip fastener shall be conditioned in the measuring atmosphere for at least 48 h.
Testing of behaviour under conditions of continuous reciprocating movement shall be carried out by a
device in accordance with Figure Z.
Apply a Force F1 in the lateral direction and a force F2 in the longitudinal direction, to the tapes on both sides half- way between the two extreme ends of the slide,where
F,in N= 3 x width of the zip fastener, in mm;
F2, inN= 2 x width of the zip fastener, in mm.
Set and apply the test loads with the slider on the zip fastener, at the bottom end, and do not change them during the test.
Ensure that the opening angle of the slider tab is approximately 30° at the upper point of reversal and approximately 60° at the lower point of reversal. When opening, F1 may be zero.Open and close the zip fastener 200 times by moving the slider over a length of traverse of 7,5 cm, a to and fro movement being designated as a stroke, at a test velocity of 30 strokes/min.BS EN ISO 5912 pdf download.Camping tents
