Snad nejd\u016fle\u017eit\u011bj\u0161\u00edm \u00fakolem termohrnku je udr\u017eet obsah tepl\u00fd, p\u0159\u00edpadn\u011b studen\u00fd. V laborato\u0159i proto naplnili hrnky vodou o teplot\u011b 95 \u00b0C \u2013 nejprve po okraj a pot\u00e9 do p\u016flky \u2013 a po \u0161esti hodin\u00e1ch v pokojov\u00e9 teplot\u011b zji\u0161\u0165ovali, o kolik stup\u0148\u016f teplota vody poklesla. Nejl\u00e9pe se v t\u00e9to zkou\u0161ce vedlo modelu Ikea Unders\u00f6ka. Teplota tekutiny v hrnku m\u011bla po \u0161esti hodin\u00e1ch hodnotu zhruba 73 \u00b0C, resp. 59 \u00b0C. \u201ePokud si vyberete tento model, bu\u010fte v\u0161ak obez\u0159etn\u00ed, ne\u017e uvyknete jeho vlastnostem.

Dobrou zn\u00e1mku pak z\u00edskal je\u0161t\u011b model Thermos Style, u kter\u00e9ho laborato\u0159 po \u0161esti hodin\u00e1ch nam\u011b\u0159ila teplotu 66 \u00b0C. Zbyl\u00e9 testovan\u00e9 v\u00fdrobky si odnesly zn\u00e1mky od uspokojiv\u00e9 po dostate\u010dnou.<\/p>\n

Celkov\u011b l\u00e9pe se testovan\u00fdm vedlo ve druh\u00e9 zkou\u0161ce tepeln\u00e9 izolace, p\u0159i kter\u00e9 se hrnky plnily chladnou vodou o teplot\u011b 5 \u00b0C.

V dal\u0161\u00edch praktick\u00fdch zkou\u0161k\u00e1ch se hodnotila obsluha, odolnost, konstrukce a zpracov\u00e1n\u00ed hrnk\u016f.

Test odolnosti byl n\u00e1ro\u010dn\u00fd pro n\u011bkolik dal\u0161\u00edch model\u016f. 600 cykl\u016f otev\u0159en\u00ed a zav\u0159en\u00ed otev\u00edrac\u00edho mechanismu nezvl\u00e1dlo celkem \u0161est v\u00fdrobk\u016f \u2013 u z\u00e1stupce zna\u010dky Stelton se tento mechanismus dokonce \u00fapln\u011b rozbil.

To zkou\u0161ky obsluhy a \u00fadr\u017eby dopadly o pozn\u00e1n\u00ed l\u00e9pe, \u0161est model\u016f z\u00edskalo velmi dobr\u00e9 hodnocen\u00ed a p\u0159i jejich pou\u017e\u00edv\u00e1n\u00ed by v\u00e1s nem\u011bly potkat \u017e\u00e1dn\u00e9 nep\u0159\u00edjemnosti, zbyl\u00fdm byly ud\u011bleny dobr\u00e9 a uspokojiv\u00e9 zn\u00e1mky, p\u0159i\u010dem\u017e \u010dast\u00fdm proh\u0159e\u0161kem, kter\u00fd se na hodnocen\u00ed obsluhy podepsal, bylo obt\u00ed\u017en\u00e9 \u010di\u0161t\u011bn\u00ed nebo chyb\u011bj\u00edc\u00ed n\u00e1vod k v\u00fdrobku.<\/p>\n

V z\u00e1v\u011bru se laborato\u0159 zam\u011b\u0159ila na chemickou anal\u00fdzu pou\u017eit\u00fdch plast\u016f, zda neobsahuj\u00ed karcinogenn\u00ed polycyklick\u00e9 aromatick\u00e9 uhlovod\u00edky (PAH).
