Heerka ASTM D6400 oo ay soo saartay Society American for Testing and Materials (ASTM) waxa uu dabooshaa balaastigga iyo alaabo ka samaysan balaastiig loogu talagalay in lagu bacrimiyo goobaha qashinka hawada hawada ee degmada iyo warshadaha.

Tilmaamaha lagu soo bandhigay heerkan waa kuwa looga baahan yahay si loo go'aamiyo in balaastikada iyo alaabada laga sameeyay balaastikada ay noqon doonaan compost heer lagu qanco, oo ay ku jiraan biodegradation-ka oo ah heer u dhigma walxaha la yaqaan ee la yaqaan. Magaca buuxa ee halbeeggani waa: ASTM D6400-19 Tilmaamaha caadiga ah ee calaamadaynta balaastikada loogu talagalay in lagu qaso hawada gudaha xarumaha dawladda hoose ama warshadaha.

Ujeedada heerkan waa in la dejiyo shuruudo lagu aqoonsanayo badeecadaha iyo agabka si lagu qanco loogu qaso goobaha bacriminta ganacsiga iyo kuwa dawladda hoose.

Alaabooyinka uu daboolay heerka ASTM D6400 waa balaastiig iyo alaab laga sameeyay balaastiig loogu talagalay in lagu qaso xaaladaha hawada hawada ee xarumaha bacriminta hawada hawada ee warshadaha halkaas oo lagu bixiyo xaaladaha heerkulbeegga (heerkulka). Heerarkani waxa uu bixiyaa shuruudaha lagu calaamadinayo agabka iyo alaabada in ay yihiin kuwo la nafaqayn karo tas-hiilaadka bacriminta warshadaha hawada, oo ay ku jiraan baakado ka samaysan caag.

Tilmaamaha lagu soo bandhigay heerkan waa kuwa looga baahan yahay si loo go'aamiyo in alaabta kama dambaysta ah, oo ay ku jiraan baakadaha loo isticmaalo balaastiigga iyo polymers sida dahaarka ama xidhayaasha, ay si qancin ah ugu dhajin doonaan dhirta bacriminta warshadaha ballaaran. Wax-soo-saarka ugu sarreeya ayaa ah mudnaan sare oo loogu talagalay kombuyuutarrada iyo heerarka dhexe ee nabaad-guurka caagga ah iyo biodegradation-ka ayaa ah mid aan la arki karin isticmaalaha ugu dambeeya sababo qurxoon dartood.

Heerka ASTM D6400 wuxuu u dhigmaa heerka ISO 17088 ee ay daabacday Hay'adda Heerarka Caalamiga ah (ISO 17088: 2008 Tilmaamaha balaastikada la burburin karo). Heerkani waxa kale oo uu qeexayaa hababka iyo shuruudaha aqoonsiga iyo calaamadaynta balaastikada iyo alaabta laga sameeyay balaastikada ku haboon dib u soo kabashada iyada oo loo marayo composting aerobic.

Ururkayagu wuxuu bixiyaa adeegyo shahaado oo aad u kala duwan oo loogu talagalay ganacsiyada qaybaha kala duwan waxayna fulisaa imtixaannada lagama maarmaanka ah, falanqaynta, xakamaynta iyo hawlaha qiimaynta ee qaabkan, waxayna had iyo jeer raacdaa heerarka gudaha iyo dibadda, xeerarka sharciga ee lagu dabaqi karo iyo guud ahaan dhaqamada la aqbali karo ee daraasaddan. Xaaladdan oo kale, codsanaya ganacsiyada,Waxa kale oo ay bixisaa shahaado compost iyo C-Label (Compost Summadaynta) adeegyada calaamadaynta compost.
