D523-08 Standard Test Method yeSpecular Gloss

Iyi chiyero inopihwa pasi peiyo yakatarwa D523; nhamba yacho pakarepo inotevera kusarudzwa inoratidza gore rekugamuchirwa kwepakutanga kana, munyaya yekudzokorora, gore rekudzokorora kwekupedzisira. Nhamba iri muzvikomberedzo inoratidza gore rekubvumirwazve kwekupedzisira . A superscripl epsilon inoratidza shanduko yekunyora kubva pakudzokorora kwekupedzisira kana kubvumidzwazve. Iyi chiyero yakatenderwa kushandiswa nemasangano eDhipatimendi reDziviriro.

1.Scope yeD523-08

1. Iyi nzira yekuyedza inovhara kuyerwa kweiyo specular gloss ye-nonmetallic specimens ye gloss mita geometries ye60, 20, uye 85 (1-7)
2.  Hukoshi hunotaurwa muma-inch-pound units hunofanirwa kutorwa seyakajairwa. Hwakoshi hwakapihwa mumaparenthesi ishanduko yemasvomhu kuSl mauniti anopihwa ruzivo chete uye asingatariswe seyakajairika.
3. Iyi chiyero hairevi kugadzirisa imwe yezvinetswa zvekuchengetedza, kana zviripo, zvine chekuita nekushandiswa kwayo. Ibasa remushandisi weiyi chiyero kumisa kwakakodzera kuchengetedza uye hutano maitiro uye kuona kushanda kwezvinodzora zvinodzora usati washandisa.

3. Chirevo

Tsanangudzo:

1. chitarisiko chinopenya chinopenya, n-chiyero chechiedza chinopenya chinoratidzwa kubva pamuenzaniso kuenda kune chinoyerera chinoratidzwa kubva panzvimbo yakajairika pasi pemamiriro akafanana ejometri. Nechinangwa chekuyera specular gloss, iyo yakajairwa nzvimbo igirazi rakakwenenzverwa.
2. specular gloss, n-iyo inoenderana neinopenya inoratidzira chinhu chemuenzaniso mumirairi yegirazi.

4. Pfupiso yeMuedzo Method

4.1 kuyerwa kunoitwa ne60, 20, kana 85 geometry. Iyo geometry yemakona uye apertures inosarudzwa kuitira kuti aya maitiro agone kushandiswa sezvinotevera:
4.1.1 Iyo 60 geometry inoshandiswa kuenzanisa mienzaniso yakawanda uye kuona kuti 200 geometry inogona kushanda rini.
4.1.2 The 20 geometry inobatsira pakuenzanisa zvienzaniso zvine 60gloss values ​​pamusoro pe70.
4.1.3 Iyo 85 geometry inoshandiswa kuenzanisa zvienzaniso zvesheen kana pedyo-mafuro kupenya. Inonyanya kushandiswa kana zvienzaniso zvine 60gloss values ​​pasi pegumi.

5.Kukosha uye Kushandiswa kweD523-08

5.1 Kubwinya kwakabatana nekugona kwepasi kuratidza chiedza chakawanda munzira dziri pedyo nechakavanzika kupfuura mune mamwe. Zviyero neiyi nzira yekuyedza zvinoenderana nekutarisa kwekuona kwekupenya kwepasi kunoitwa pane angangoita makona anoenderana.
5.1.1 Kuyerwa kuyerwa kupenya nenzira iyi yekuyedza kunowanikwa nekuenzanisa kutarisisa kubva kumuenzaniso kune iyo kubva kune dema gloss mwero. Sezvo specular reflectance inoenderanawo nepamusoro refractive index yemuenzaniso, kuyerwa gloss ratings inoshanduka sezvo iyo surface refractive index inoshanduka.Mukuwana zviyero zvekuona gloss, zvisinei, itsika kuenzanisa specular reflectances yezviyero zviviri zvine zvakafanana surface refractive. indices.
5.2 Zvimwe zvinoonekwa zvechitarisiko chepamusoro, senge kusiyanisa kwemifananidzo inotaridzwa, mhute yekuratidzira, uye magadzirirwo, anowanzo kubatanidzwa mukuongororwa kwegloss.
Test Method E 430 inosanganisira matekiniki ekuyeresa ese ari maviri musiyano-we-chifananidzo gloss uye inoratidzira haze. Muedzo nzira D4039 inopa imwe nzira yekuyera kuratidzwa haze.
5.3 Ruzivo rudiki pamusoro pehukama hwenhamba nenhamba dzepfungwa dzespecular gloss raburitswa. Nekudaro, mumashandisirwo mazhinji zvikero zvegloss zveiyi nzira yekuyedza hee akapa chiyero chekuwedzera chezviyero zvakavharwa zvakabvumirana zvakanaka nekuyera kwekuona.
5.4 kana zvienzaniso zvichisiyana zvakanyanya mukuonekwa kupenya kana ruvara, kana zvese zviri zviviri, zvinofananidzwa, kusawirirana kunogona kusangana muhukama pakati pekuona gloss musiyano ratings uye instrumental gloss kuverenga misiyano.
