Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International

Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 5912 was prepared by Technical Committee ISO/TC 83, Sports and recreational equipment, Subcommittee

SC 2, Camping tents.

This fourth edition replaces part of ISO 10966:2005 and cancels and replaces the third edition of this International

Standard (ISO 5912:2003), which has been technically revised to incorporate the following changes:

a) inclusion of revised requirements for fabric for camping tents from ISO 10966:2005;

b) deletion of requirements on stability performance;
c) introduction of three levels of performance for camping tents;
d) clarification of consumer information regarding ventilation;
e) change of test method for flame retardant fabric;
f) rain test brought into line with industry best practice;

g) addition of requirements to address risks related to new styles of tents which include squeeze and sheer points;

h) modification of size of sleeping areas.

0 Introduction
0.1 General

The principal objective of this International Standard is to simplify it from previous editions by deleting

requirements and test methods which did not prove to be reproducible, or which do not contribute to the safety

and quality performance of camping tents.

One such deleted parameter was stability performance. Stability was considered to be an important issue

for the performance of a tent, however there was no reproducible test method available when developing this

International Standard. When a suitable test or simulated test can be developed, it is the intention of ISO/TC 83

to include a more specific requirement in this International Standard.
For marquees and larger textile structures, see Reference [3].
0.2 Environmental considerations

Every product affects the environment in the course of its lifecycle from raw material acquisition through

production, distribution and use, to disposal. Environmental impacts are consequences of the consumption

of energy and resources and the generation of waste, as well as the emission of substances into air, water

and soil. The magnitude of the environmental impacts during the various lifecycle changes depends on a

number of choices made in the design of the product, such as the materials used, production methods, and

considerations related to maintenance and recycling. Manufacturers and distributors of camping tents should

consider the environmental impact of their product by, for example:
— avoiding the use of environmentally harmful substances;

— selecting the best available technology and techniques to reduce consumption of energy and materials;

— considering use of recycled materials for product and packaging;

— encouraging responsible end of life disposal by the user including guidance on separation and identification

of any recyclable components and packaging;

— using materials, components, and manufacturing facilities which have declared documented

environmental policies.

6.1.1.2 Dimensional stability

When tested in accordance with ISO 7771 using a cycle of 2 h, the dimensional change shall not exceed ±3 %.

6.1.1.3 Flammability
6.1.1.3.1 General

If the fabrics of a camping tent are claimed to have flame retardant properties they shall be tested when new

and shall comply as required to 6.1.1.3.2, 6.1.1.3.3 and 6.1.1.3.4. See Table 2, Note 1 for information about the

use of applied chemical finishes to produce flame retardant properties.
6.1.1.3.2 Outer tent material

When tested in accordance with ISO 6941:2003, Procedure A (using a 10 s ignition time, surface ignition), no

marker threads shall be severed, there shall be no flaming debris, there shall be no flame to either vertical edge

of the test specimen, no single sample shall show afterflame time exceeding 10 s, and the average afterflame

time shall not exceed 6 s.
6.1.1.3.3 Inner tent material

When tested in accordance with ISO 6941, Procedure A (using a 10 s ignition time, surface ignition), no marker

threads shall be severed, there shall be flaming debris on no more than two of the tested samples, there shall

be no flame to either vertical edge of the test specimen, no single sample shall show afterflame exceeding

20 s, and the average afterflame time shall not exceed 12 s. Should a single sample fail, the test shall be

repeated once more; if the fabric fails a second time then the fabric is deemed to have failed the test.

6.1.1.3.4 Groundsheet

When tested in accordance with ISO 6925, the radius of burn shall be less than 35 mm.

---------------------- Page: 18 ----------------------
SIST EN ISO 5912:2011
ISO 5912:2011(E)
6.1.2 Ground fastening

At least one ground fastening shall be provided for each corner, or four ground fasteners as a minimum if the

tent is not rectangular.
6.1.3 Protective measures

Points on the groundsheet which are in contact with frame parts shall be suitably protected.

6.1.4 Ventilation
6.1.4.1 General

In order to reduce the risk of suffocation, tents shall be designed to maintain a circulation of air and minimize

the opportunity for a build-up of harmful gases to dangerous levels within the sleeping areas.

NOTE See Clause 9 for warning label information.
6.1.4.2 Sealed tents

In order to provide a sufficient circulation of air, a minimum of two ventilation openings shall be provided, each

of which shall be at least 100 cm per person. These openings shall be of such a design that when opened they

cannot be closed by prevailing weather conditions.

NOTE In order to allow a suitable circulation of fresh air and to prevent a build-up of carbon dioxide in the lower areas

of the tent, it is recommended that one of these vents be placed less than 1/3 of the total height of the tent from the ground,

and the other placed in the upper 1/3 of the height of the tent. In the case of double skin tents, an area of 2/3 of the inner

tent excluding the groundsheet should be made from an air permeable material.
6.1.4.3 Double skin tents

By choosing suitable materials and product design, a permanent circulation of air to reduce condensation

shall be possible.
6.1.5 Tent exits

Tents with a sleeping capacity of four or more persons shall have an exit with a minimum area of 0,9 m and a

minimum width of 50 cm. Where two exits are provided, this size requirement only applies to the first.

Tent exits may be closed using a zip fastener (see 6.2.2) or any other system, provided that they can be opened

easily from the bottom, if the exit is higher than 100 cm.
NOTE This provides an escape route for children.
6.1.6 Insect protection
Doors and openings for inner tents shall be insect-proof when they are closed.
Insect resistant nets, if used, shall have a maximum mesh size of 1 mm × 1 mm.
6.1.7 Resistance to penetration by rain

The resistance of the tent shall be such that no water penetrates the tent interior except a light mist during the

first 2 min, when the rain test according to 8.3 is carried out.

The outer fabric of the tent shall not come into contact with the inner fabric unless designed to do so, e.g. pole

sleeves of geodesic tents (see Figure 2).

If the fabric requires a pre-conditioning (due to soaking behaviour of seams) it shall be made according to 8.3.

If additional preparation work (e.g. seam sealing) is recommended by the manufacturer, it should be carried out

in accordance with information supplied by the manufacturer.
6.2 Requirements for components
6.2.1 Frame
6.2.1.1 General

All metal parts shall be such that there is no change at the end of the test according to 8.2, except for minor
