Standards are not only crucial for obtaining a certification practical use, but also an essential guidance inferring how and what to simulate as well test experimentally. This paper examines the potential applicability of existing standards from various domains, including aerospace automotive, Wing-Structure- Integrated high-pressure Hydrogen Tanks (SWITHs). It highlights associated challenges uncertainties, acknowledging absence single, all-encompassing standard SWITHs. 
 We embark on exploration aimed at identifying alternative that best suited The analysis scrutinizes could potentially facilitate SWITH certification, with particular focus inclusivity externally loaded hydrogen tanks. Assessment criteria established filter meet needs Through this process, we identify two key present themselves most promising alternatives.
 Moreover, delineate technical constraints involved in selecting maximum nominal working pressure tanks intended burst tests. Our findings reveal current upper limit 525 bar, imposed by limitations facilities. study underscores these should serve flexible guiding frameworks rather than rigid protocols, encouraging progressive development field.
