I-D523-08 Indlela yoVavanyo oluMgangatho lwe-Specular Gloss

Lo mgangatho ukhutshwa phantsi kobizo olusisigxina D523; Inani elilandela emva konyulo libonisa unyaka wokwamkelwa kwasekuqaleni okanye, kwimeko yohlaziyo, unyaka wohlaziyo lokugqibela. Inani elikwizibiyeli libonisa unyaka wokwamkelwa kwakhona kokugqibela . I-epsilon ye-superscripl ibonisa utshintsho lokuhlela ukususela kuhlaziyo lokugqibela okanye ukuvunywa kwakhona. Lo mgangatho uvunyiwe ukuba usetyenziswe ngamaziko eSebe lezoKhuselo.

1.Ububanzi be-D523-08

1. Le ndlela yovavanyo igubungela umlinganiselo weglosi eyodwa yeesampulu ezingezizo ezentsimbi kwiglosi yemitha yejometri yama-60, ama-20, nama-85 (1-7)
2.  Amaxabiso achazwe kwiiyunithi ze-inch-pound kufuneka athathwe njengomgangatho. Amaxabiso anikwe kwizibiyeli luguqulelo lwemathematika ukuya kwiiyunithi ze-Sl ezibonelelwe ngolwazi kuphela kwaye azithathwa njengomgangatho.
3. Lo mgangatho awufuni kujongana neenkxalabo zokhuseleko, ukuba zikhona, ezinxulumene nokusetyenziswa kwayo. Luxanduva lomsebenzisi walo mgangatho ukuseka ukhuseleko olufanelekileyo kunye neendlela zempilo kunye nokumisela ukusetyenziswa kwemida yokulawula ngaphambi kokusetyenziswa.

2.Amaxwebhu ekubhekiselwa kuwo

IMigangatho ye-ASTM:

• I-D 823 yeZenzo zokuVelisa iifilimu zoButyebe obufanayo bePeyinti, iVarnish, kunye neeMveliso eziNxulumeneyo kwiiPaneli zoVavanyo
• D 3964 Ukuziqhelanisa noKhetho lweSampulu zoKugquma kwiMilinganiselo yembonakalo
• D 3980 Ukuziqhelanisa noVavanyo lweLabhoratri ePhakathi kwePaint kunye neMathiriyeli eNxulumeneyo
• Indlela yoVavanyo lwe-D4039 yokuBonisa inkungu yeMihlaba eGqamkileyo
• E 97 Indlela yoVavanyo lweFactor yeReflectation yeDirectional, 45-Deg 0-Deg, yeMifanekiso eOpaque yi-Broad-Band Filter Reflectometry
• E 430 iiNdlela zoVavanyo loMlinganiso woBumenyemeze beMigangatho yeglosi ePhakamileyo ngeGoniophotometry efinyeziweyo

3. Isigama

Ingcaciso:

1. into ebonisa ukukhanya okukhanyayo, n-umyinge we-flux ekhanyayo ebonakaliswe ukusuka kumzekelo ukuya kumsinga obonakaliswe ukusuka kumgangatho oqhelekileyo phantsi kweemeko ezifanayo zejometri. Ngenjongo yokulinganisa iglosi ekhethekileyo, umgangatho osemgangathweni yiglasi ekhazimlisiweyo.
2. Iglosi eyodwa, n-imbonakalo ekhanyayo ehambelanayo yesampulu kwicala lesipili.

4. Isishwankathelo seNdlela yoVavanyo

4.1 Imilinganiselo yenziwa nge-60, 20, okanye 85 geometry. Ijometri yee-engile kunye ne-apertures ikhethwa ukuze ezi nkqubo zisetyenziswe ngolu hlobo lulandelayo:
4.1.1 Ijometri engama-60 isetyenziselwa ukuthelekisa uninzi lwesampulu kunye nokumisela ukuba ijometri yama-200 inokusebenza nini ngakumbi.
4.1.2 Ijiyometri engama-20 iluncedo ekuthelekiseni iisampulu ezinamaxabiso angama-60 egloss aphezulu kuno-70.
4.1.3 Ijiyometri engama-85 isetyenziselwa ukuthelekisa imizekelo yesheen okanye ukuqaqamba kwedlelo elikufutshane. Isetyenziswa rhoqo xa iisampulu zinamaxabiso angama-60gloss angaphantsi kwe-10.

5.Ukubaluleka kunye nokusetyenziswa kwe-D523-08

5.1 Iglosi inxulunyaniswa nomthamo womphezulu wokubonakalisa ukukhanya ngakumbi kwiindlela ezikufutshane ne-specular kunakwabanye. Imilinganiselo ngale ndlela yovavanyo ihambelana nokubonwa okubonakalayo kokukhanya komphezulu okwenziwa malunga nee-engile ezihambelanayo.
5.1.1 Iireyithingi zeglosi elinganisiweyo ngolu hlobo lovavanyo zifunyanwa ngokuthelekisa imbonakalo eyodwa ukusuka kumzekelo ukuya kumgangatho weglosi emnyama. Kuba ukubonakaliswa okukodwa kuxhomekeke kwisalathiso somphezulu we-refractive wesampulu, umlinganiselo weglosi elinganisiweyo uyatshintsha njengoko isalathisi seglosi sitshintsha. indices.
5.2 Eminye imiba yembonakalo yomphezulu, enjengokwahluka kwemifanekiso ebonakalisiweyo, inkungu ebonisa ukukhanya, kunye nokwakheka kwayo, isoloko ibandakanyeka kuvavanyo lweglosi.
Indlela yoVavanyo ye-E 430 ibandakanya ubuchule bomlinganiselo weglosi yomfanekiso ocacileyo kunye nenkungu ebonisa. Indlela yovavanyo i-D4039 ibonelela ngenye inkqubo yokulinganisa inkungu ebonakalisa imbonakalo.
5.3 Ingcaciso encinci malunga nonxulumano lwamanani kunye nekhefu lokuqonda kwiglosi ekhethekileyo iye yapapashwa. Nangona kunjalo, kwizicelo ezininzi izikali zeglosi zale ndlela yovavanyo zibonelele ngesixhobo sokukalwa kweesampulu ezigqunyiweyo ezivumelane kakuhle nokukalwa okubonakalayo.
5.4 xa iisampulu zohluka ngokubanzi kwiglosi ebonwayo okanye umbala,okanye zombini , zithelekiswe, ukungangqamani kunokuqubisana nobudlelwane phakathi komahluko weglosi yokubonwayo kunye nomahluko wokufunda kwiglosi yesixhobo.
