rockwell hardness guarantee hr30t garantovana tvrdoća po Rokvelu (na skali) HR30T Explanation: postavljeno pitanje u principu znači kolika je garantovana Rokvelova tvrdoća na skali HR30T ("na skali" se može slobodno izostaviti), kao što je npr. pojam garantovane zatezne čvrstoće: http://www.tehnickaue.edu.rs/srp/cas/?conid=347 NL370-17- има гарантовану затезну чврстоћу Rm = 370 N/mm2 ; U sledećem primeru, garantovana tvrdoća je 370 - 430 na Brinelovoj skali HBW: http://www.google.rs/url?sa=t&rct=j&q=&esrc=s&source=web&cd=... Hardness guarantee Hardness Brinell hardness test, HBW according to EN ISO 6506-1, is performed 1 - 2 mm below the plate surface once per heat and 40 tonnes. HBW = 370 - 430 |

rockwell hardness guarantee hr30t Гаранција тврдоће по Роквелу одрећена методом HR30T Explanation: предлог -------------------------------------------------- Note added at 19 hrs (2014-03-22 13:59:34 GMT) -------------------------------------------------- http://www.rgf.bg.ac.rs/predmet/RO/III semestar/Tehnologija ... На страни 60 је Tabela 11. Metode za određivanje Rokvelove tvrdoće А, на страни 59 стоји ''Metode za ispitivanje tvrdoće po Rokvelu grupisane su u tri grupe, kako je to dato u tabeli 11.'' Тако да, ако сам добро разумела, у оквиру саме Роквелове методе, постоје (под)методе, а ознаке попут ове HR30T говоре о карактеристикама поступка (који је утискивач, која сила утискивања, која ознака тврдоће). |

Reference: HR30T Reference information: HR30T - (jedna od) skala tvrdoće po Rokvelu Pogledajte ovde u vrhu tabele, i paragraf odmah ispod tabele: http://books.google.rs/books?id=a6ZDtBOlngQC&pg=PA174&lpg=PA... Vickers Hardness HV Brinell Hardness HBS Rockwell Hardness HRB HRF HR15T HR30T HR45T --- When reporting converted hardness values, the measured hardness value and hardness scale should be indicated in parenthes as in the following example: 200 HV (190 HBW) http://www.osc-tokyo-japan.sakura.ne.jp/osc/product/OSC971UU... The hardness of tinplate is required to test by Superficial Rockwell hardness tester OSC971UU500 series in HR30T scale with diamond spot raised anvil internationally. Thus the result is written in HR30Tm. 1) When the thickness is below 0.21mm, we select HR15T scale. Then we convert the value into HR30T scale. 2) When the thickness is between 0.21mm and 0.55mm, we select HR30T scale and diamond spot raised anvil. Thus we get value in HR30Tm directly. 3) When the thickness is above 0.55mm, we select HR45T scale. Then we convert the value into HR30T scale. |
