Fahamka ASTM F2100-19 / EN14683: HEERARKA 2019
Doorashada maaskaro ku habboon habraac gaar ah waa qayb muhiim ah oo ka mid ah qalabkaaga ilaalinta shakhsi ahaaneed (PP) .In kasta oo waji-xidhashadu u ekaan karto isku mid , maaskaro kastaa waxa uu leeyahay farqi muuqda oo saameeya tayada iyo heerka sifaynta .Fahmidda heerka waxqabadka ASTM ee maaskaro kasta waxay kaa caawin kartaa samaynta habka xulashada mid fudud oo hubi in maaskaradaadu ay bixin doonto sifaynta habboon.
Alaabooyinka waji-xidhka caafimaadka ee lagu daboolay qeexida ASTM waxaa loo qoondeeyay mid ama in ka badan oo ka mid ah heerarka waxqabadka ee soo socda iyadoo lagu saleynayo sifooyinka waxqabadka ee walxaha la isticmaalay:
| ASTM F2100-19 | EN 14683: 2019 Heerarka Caqabadaha | |||||
| BFE% | Heerka 1 | Heerka 2 | Heerka 3 | Nooca 1 | Nooca 2 | Nooca 3 |
| PFE % | ≥ 95 | ≥ 98 | ≥ 95 | ≥ 98 | ||
| Dhiiga synthetic | ≥ 95 | ≥ 98 | Looma baahna | |||
| Cadaadis Kala Duwan | Ku dhaaf 80 mmhg | Ku gudub 120 mmhg | Ku gudub 160 mmhg | Looma baahna | Ku gudub 120 mmhg | |

| La jaanqaadka noole | Tilmaanta 510K waxay ku talinaysaa in la tijaabiyo ISO10993 | Dhammaystir qiimaynta sida waafaqsan ISO10993 | ||||
Dhiiga Synthritic* waxay ka dhigan tahay iska caabbinta maaskarada ee dhexgalka dhiigga synthetic ee cadaadiska hoos yimaada (mmhg).Waxay cabbirtaa awoodda dhismaha maaskaro ee maaskaro si loo yareeyo qulqulka dareeraha ku safraya walxaha suurtagalka ah inay la xiriiraan qofka xidhan .Mar kasta oo ay sarreeyaan iska caabbinta dareeraha ( sifaynta), ayaa ka sii wanaagsan ilaalinta
BFE (Wax ku oolnimada Sifeynta bakteeriyada)waxay ka dhigan tahay boqolleyda hawo-mareenada lagu sifeeyay cabbirka 3 microns.Waa cabbirka waxtarka maaskarada ee shaandhaynta bakteeriyada soo dhex mara
PFE (waxtarka sifaynta qayb-yar-yar)waxay ka dhigan tahay boqolkiiba qaybaha submicron-ka lagu sifeeyay 0.1 micron PFE waa cabbirka waxtarka maaskarada ee walxaha shaandhaynta ee dhex mara.Baaxadda walxaha la sifeeyay waa muhiim
DELTA P (cadaadiska kala duwan)waxay ka dhigan tahay hoos u dhaca cadaadiska ee maaskarada ama iska caabinta socodka hawada inmmh2o / cm2.Tani waxay go'aamisaa iska caabbinta neefsashada-marka uu sareeyo Delta P , waa yaraanta awoodda neefsiga, laakiin si fiican ayaa loo sifeeyaa.
Daboolashadu waxay cabbirtaa faafidda ololka walxaha maaskaro
