Mugihe ibipimo bya PFI na ISO bisa nkaho bisa muburyo bwinshi, ni ngombwa kumenya itandukaniro ryibonekeje muburyo bwihariye hamwe nuburyo bwikizamini buvugwa, kuko PFI na ISO ntabwo buri gihe bigereranywa.

Vuba aha, nasabwe kugereranya uburyo nibisobanuro byavuzwe mubipimo bya PFI nibisa na ISO 17225-2 bisa.

Wibuke ko ibipimo bya PFI byatejwe imbere mu nganda zo mu bwoko bwa pellet zo muri Amerika y'Amajyaruguru, mu gihe akenshi, ibipimo bishya bya ISO byasohotse bisa neza n’ibyahoze ari EN, byandikiwe ku masoko y’Uburayi.ENplus na CANplus ubu bivuga ibisobanuro byamasomo meza A1, A2 na B, nkuko bigaragara muri ISO 17225-2, ariko ababikora cyane cyane bakora "icyiciro cya A1."

Na none, mugihe ibipimo bya PFI bitanga ibipimo byerekana amanota meza, asanzwe kandi yingirakamaro, umubare munini wabakora ibicuruzwa bakora progaramu yo hejuru.Uyu mwitozo ugereranya ibisabwa mu cyiciro cya mbere cya PFI na ISO 17225-2 A1.

Ibisobanuro bya PFI byemerera ubucucike buri hagati ya pound 40 na 48 kuri metero kibe, mugihe ISO 17225-2 ivuga intera y'ibiro 600 kugeza 750 (kg) kuri metero kibe.(37.5 kugeza 46.8 pound kuri metero kibe).Uburyo bwo kwipimisha buratandukanye kuberako bakoresha ibikoresho bifite ubunini butandukanye, uburyo butandukanye bwo guhuza hamwe nuburebure butandukanye.Usibye ibyo bitandukanye, ubwo buryo bwombi bufite ubwinshi bwimpinduka nkibisubizo byikizamini biterwa nubuhanga bwihariye.Nubwo ibyo byose bitandukaniye hamwe nibihinduka byihariye, ubwo buryo bubiri busa nkaho butanga ibisubizo bisa.

Ikigereranyo cya diameter ya PFI ni 0.230 kugeza kuri 0.285 (5.84 kugeza kuri 7.24 milimetero (mm) cyangwa mm 8, buri kimwe gifite kwihanganira wongeyeho cyangwa ukuyemo mm 1, bigatuma hashobora kuba intera ya mm 5 kugeza kuri 9 (0.197 kugeza 0.354 santimetero) ) ibipimo bipfa, byitezwe ko ababikora batangaza mm 6. Ntabwo bizwi neza uburyo ibicuruzwa bya mm 8 bya diameter byagira ingaruka kumikorere y'itanura.

Kuramba, uburyo bwa PFI bukurikiza uburyo bwa tumbler, aho urugero rwa chambre rufite santimetero 12 kuri santimetero 12 kuri santimetero 5.5 (305 mm kuri 305 mm na mm 140).Uburyo bwa ISO bukoresha tumbler isa ntoya gato (300 mm kuri 300 mm na mm 120).Ntabwo nabonye itandukaniro mubipimo by'agasanduku kugirango bitere itandukaniro rinini mubisubizo by'ibizamini, ariko mubitekerezo, agasanduku kanini gato gashobora gutanga ikizamini gikaze kuburyo bwa PFI.

PFI isobanura ihazabu nkibikoresho binyura kuri ecran imwe ya munani ya mesh ya mesh (3.175-mm ya mwobo).Kuri ISO 17225-2, ihazabu isobanurwa nkibikoresho binyura kuri ecran ya mm 3.15.Nubwo ibipimo bya ecran 3.175 na 3.15 bisa nkaho, kubera ko ecran ya PFI ifite umwobo wa kare na ecran ya ISO ifite umwobo uzengurutse, itandukaniro mubunini bwa aperture ni 30%.Nkibyo, ikizamini cya PFI gishyira igice kinini cyibikoresho nk’amande bigatuma bigora gutsinda ikizamini cy’amande ya PFI, nubwo gifite amande agereranywa asabwa kuri ISO (byombi bivuga amande angana na 0.5 ku ijana kubintu bipfunyitse).Mubyongeyeho, ibi bitera ibisubizo birambye ibisubizo bigera kuri 0.7 munsi iyo bipimishije hakoreshejwe uburyo bwa PFI.

Kubirimo ivu, PFI na ISO zombi zikoresha ubushyuhe busa cyane bwo gukaraba, dogere selisiyusi 580 kugeza kuri 600 kuri PFI, na 550 C kuri ISO.Ntabwo nabonye itandukaniro rinini hagati yubushyuhe, kandi ndatekereza kuburyo bubiri bwo gutanga ibisubizo byagereranijwe.Umupaka wa PFI kumivu ni 1 ku ijana, naho ISO 17225-2 ntarengwa ivu ni 0.7%.

Kubijyanye n'uburebure, PFI ntabwo yemerera kurenza 1 ku ijana kurenza santimetero 1.5 (38.1 mm), mugihe ISO itemerera kurenza 1 ku ijana kurenza mm 40 (santimetero 1.57) kandi nta pelleti irenga mm 45.Iyo ugereranije mm 38.1 mm 40 mm, ikizamini cya PFI kirakomeye, ariko, ibisobanuro bya ISO ko nta pellet ishobora kurenza mm 45 bishobora gutuma ISO isobanurwa neza.Kuburyo bwikizamini, ikizamini cya PFI kirasobanutse neza, muburyo ikizamini gikozwe byibuze urugero ntarengwa rwa pound 2,5 (garama 1,134) mugihe ikizamini cya ISO gikorerwa kuri garama 30 kugeza 40.

PFI na ISO bakoresha uburyo bwa calorimeter kugirango bamenye agaciro ko gushyushya, kandi ibizamini byombi bitanga ibisubizo bigereranywa biturutse kubikoresho.Kuri ISO 17225-2, ariko, imipaka yagenwe kubintu byingufu igaragazwa nkigiciro cyiza cya calorificateur, nanone cyitwa agaciro gake.Kuri PFI, agaciro ko gushyushya kugaragazwa nkigiciro kinini cya calorificateur, cyangwa agaciro keza cyane (HHV).Ibipimo ntabwo bigereranywa neza.ISO itanga imipaka ko pelleti A1 igomba kuba irenze cyangwa ingana na kilowatt-4,6-isaha kuri kg (bihwanye na 7119 Btu kuri pound).Ibipimo bya PFI bisaba uwabikoze kwerekana byibuze HHV nkuko yakiriwe.

Uburyo bwa ISO kuri chlorine bwerekana ion chromatografiya nkuburyo bwibanze, ariko ifite ururimi rwo kwemerera tekinike zisesengura zitaziguye.PFI yerekana uburyo bwinshi bwemewe.Byose biratandukanye mumipaka yabyo hamwe nibikoresho bisabwa.Umupaka wa PFI kuri chlorine ni miligarama 300 (mg), ku kilo (kg) naho ISO isabwa ni 200 mg kuri kg.

Muri iki gihe PFI ntabwo ifite ibyuma byashyizwe ku rutonde, kandi nta buryo bwo gupima bwerekanwe.ISO ifite imipaka yibyuma umunani, ikanerekana uburyo bwa ISO bwo gupima ibyuma.ISO 17225-2 irerekana kandi ibisabwa kubintu byinshi byongeweho bitashyizwe mubipimo bya PFI, harimo ubushyuhe bwo guhindura ibintu, azote na sulferi.

Mugihe ibipimo bya PFI na ISO bisa nkaho bisa muburyo bwinshi, ni ngombwa kumenya itandukaniro ryibonekeje muburyo bwihariye hamwe nuburyo bwikizamini buvugwa, kuko PFI na ISO ntabwo buri gihe bigereranywa.
