3、ntaineering. It establishes requirementsfor the testing and marking of tents.1.2 This test method may contain test methods that do notentirely simulate real life situations. This test method isdesigned to give reproducible results in a laboratory andthereby a means for product comparison.1.3 This st

4、andard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Terminology2.1 Definiti

5、ons of Terms Specific to This Standard:2.1.1 tenta portable shelter made primarily of fabricweighing less than 3 oz/yd2, designed to be carried by theoccupants for while backpacking or mountaineering.2.1.2 usable headroomthe interior vertical measurementof a tent measured from the tent floor to the

6、high point on theceiling using a simple fixture that simulates an average usershead.3. Significance and Use3.1 This test method can be used to quantify and compareheadroom of backpacking and mountaineering tents. Themeasured headroom can be used as a manufacturing standardor a measurement that can b

7、e used by consumers to comparethe interior height of a variety of tents, or both.4. Apparatus4.1 Specifications for Headroom Measurement Fixture (seeFig. 1):4.1.1 Styrofoam ball 6 inches in diameter (mean width ofmale head = 6.1 in.).24.1.2 Tape Measure,14 in. GraduationsThe tape ismounted into the

8、bottom of the Styrofoam ball, and the first 6inches are removed from the tape. In this way, the reading willbe simple and accurate.5. Summary of Test Method5.1 The tent should be pitched on a flat surface in accor-dance with the companys supplied pitching instructions .5.2 The fixture shall be place

9、d inside the tent. The ball israised until it comes into contact with the ceiling, wall, poles,or any other obstructions inside the tent.5.3 The tape measure will now be hanging directly belowthe ball. The headroom measurement will be where themeasuring tape hits the tent floor. If the tent does not

10、 have afloor, record the measurement to the surface the tent has beenset up on.6. Conditioning6.1 Tests may be completed under ambient conditions. Incases of dispute, test samples shall be conditioned in accor-dance with 6.2.6.2 The tent samples are first erected and dried in anatmosphere with a rel

11、ative humidity of less than 10 % for aminimum period of 24 h. They are then placed in an atmo-sphere of 50 6 5 % relative humidity, 20 6 2 C for aminimum period of 72 h. Tests may then be done outside theconditioning room, but the temperature shall be 23 6 5Candthe tests shall begin within 5 min. of

12、 removal from condition-ing and be completed within 4 h.7. Sampling, Test Specimens, and Test Units7.1 The tent test specimen shall be new and in unusedcondition. When possible, it shall be selected randomly from aproduction lot of a given model of tent. It shall conform in allrespects to the manufa
