a. Application. Ibis B tbod is used eben tbe test Itee is lllwly % be deployed in areas iMe cliKtie oonditimis will induoe high iratures witbln tbe test itea. These procedures will be used lAten It is Jtjdged that tbe test lt*M perfonanoe can be verified by chairiber expoaure to controlled air teieratisea and that tbe high teiicMiratis*e effecta have not been identified during other teata (e.g., teaperatisfe-altitude. solar radiation).

b. Test objectives. Tbe prinaoy objectives of tbe blgb-teafieratiBv tests are to determine if:

(1) Tbe test iteai will operate without degradation In. or after atorage in. a climate lAiicfa inducea high teaperaturea within the teat Itaa.

(2) The teat item can be operated and bandied without affecting Ita


(3) Tbe teat item ia aafe dxs*ing and following bigh-teiqperatia<e esqx>suf>e.

c. Restrictions. This method is not applicable for:

(1) Evalxjation of equipomnt in a higb-teqierature environaent solar rediation contributes to differential heating or actinic (photochamical) effects. For

such an environment, use mathod 905.3.

1/ Critical conponents of the test item directly affect the fistctloning of equipment. The tenperaturas that these conponents are of priaa eoncem, regardless of the ambient conditions or slcln tenperature of the test itmn. The response teaperature(s) is the result of the exposinre which is achieved from the temperature cvcle, duration, and thermal/fdiysical properties of the equipment.

(2) IdentiflOAtlon of tiiDB-dependent perfonaance degradation lilch occurs during long-term storage in or ^ to high tenperatxires. (Such testing nould require extended test .) Selection of test duraticr,s ! conditions for sush extended expcs-wPa sisuld have to be based a specific test program requirement and consideration given to natural environmental testing.

(3) Bqulpnent to be installed wAiere the influence of altitude or cooling air may be significant.

d. Sequence. (See (Seneral Requirements, 5.1.4) The high-ten >erature test is

usually schsduled early in the test sequence before initial dynamic transportation tests. This test contribute significantly to the results of low pressure testing of seals.

e. Test variations. Tbls method provides a choice of two siibtests: Procedures I (Storage) and II (Qpermtion).

(1) The test procedure selectiwt is based \:

(a) The operational purpose of the test item.

lb) Tnm natwal eireurastanees.

(c) Tbe test data required to determine whether the operational purpose of the test item has been met.

(3) The related test conditions that may be used during the test are determined by:

(a) Tbe anticipated temperature and humidity ranges of the geogreshical deplwrnant area.

(b) Test item response teii>erature(s) (critical conponent teaperature). 1/

(c) Tbe anticipated dwation of exposure at the deployment area.

The teat conditiona and dtsition can be establiahed from field iseasupemttnta or can be derived froai information provided within this procedtre. There are two climatic regions (figure 4a. section 4} titere hiffi storage tenperatures are typically encountered: not Dry and Basic Hot. In eaeh cf these clisatic regions, the ssBxiasusa response t apsrature cf tbe test ites may be higher than the maxiaun asbient air tanperatin becauae the beating from solar radiation is greater an material than it is on the free atmosphere. The storage situation must be considered with respect to:

a. Exposure to solar radiation: Is this exposure directly on the test item, shipping container, protective pacdcage shelter, etc.?

(1) Aabient air conditions. Of interest are the most severe conditions that materiel, wtiich could be deployed in any clinatic area of the world, would experience cover in fully ventilated locations Budh as open cabins, sw-shaded areas, and underside regions of aircraft iiei*e the test item is shaded from direct solar beating, ilnbient air tenperature and humidity conditions are those measured In standard meteorological shelters at a height of 1.2 to 1.8 meters (4 to feet) above the grotsid. If field data are not available, the conditions for this exposure nay be approximated from tables 501.3-1 and 501.3-11. Table 501.3-III gives a sunann of high-tenperature diumal carcle ranges for different areas of the world.

1- Procedvjre II - QperatioT Procedure II Is ueed to determine Uie performance of the test item dts*ing exposure to hieh-teofMrature conditions. In most cases, this prooedts4 shall be preceded by procedure I, \jnless the test item is not intended to be stored in a high-tenperattoTe environment. The operational test differs from the storage test in that the test item is conditioned to tenperaturas determined to be applicable to or resulting from exposure in its operational configuration. Once broiight to this tenperature, the test item is operated to determine performance characteristics. The operational phase can be acccmpllshad by:

Exposure to cyclic chancer conditions with the test item operating either

continuously or dljririg the period of saxinua

b. to constant tenperature wiwre the test item will be operated following test item tenperature stabilization. The tenperattae level for this will either be given by the requirements docinants, derived from the field data, or derived from the response to the cyclic chanber conditions.

a. Type of exDosure. In order to determine the test tenperatures, the way in iilcb the test item is exposed to beat must be detexnnined first. The exposure oondltions that must be considered include:
