PSTC 16<\/strong> je norma vydan\u00e1 Radou pro lepic\u00ed p\u00e1sky citliv\u00e9 na tlak (PSTC), kter\u00e1 popisuje postupy pro m\u011b\u0159en\u00ed lepic\u00ed smy\u010dky lepidel citliv\u00fdch na tlak. Tato zkou\u0161ka hodnot\u00ed schopnost lepidla p\u0159ilnout k povrchu pod okam\u017eit\u00fdm tlakem, co\u017e je rozhoduj\u00edc\u00ed faktor pro ur\u010den\u00ed toho, jak dob\u0159e bude p\u00e1ska fungovat za norm\u00e1ln\u00edch podm\u00ednek.
