Ngophuhliso loluntu, imiba yokhuseleko lwezithuthi ifumene ingqwalasela eyongeziweyo, kwaye ukusebenza kokhuseleko lwezithuthi kuye kwatsala ingqalelo engakumbi. Kungekudala, umgangatho omtsha wokhuseleko lwesithuthi - isatifikethi se-PAS 68 sitsale ingqalelo ebanzi kwaye ibe yinto eshushu kwishishini.
Isatifikethi se-PAS 68 sibhekiselele kumgangatho okhutshwe liZiko lemiGangatho yaseBritani (BSI) ukuvavanya ukuchasana kwempembelelo yesithuthi. Lo mgangatho awugxininisi kuphela ekusebenzeni kokhuseleko lwesithuthi ngokwawo, kodwa ubandakanya ukhuseleko lweziseko zokuthutha. Isatifikethi se-PAS 68 sithathwa ngokubanzi njengeyona migangatho ingqongqo yokhuseleko lwezithuthi ehlabathini. Inkqubo yovavanyo lwayo ingqongqo kwaye icokisekile, igubungela izinto ezininzi, kubandakanya noyilo lwesakhiwo sesithuthi, amandla ezinto eziphathekayo, uvavanyo lokuwa, njl.
