ASTM E140, Change 12B, – Practical Firmness Sales Tables to have Gold and silver Relationships Among Brinell Firmness, Vickers Stiffness, Rockwell Firmness, Shallow Stiffness, Knoop Stiffness, Scleroscope Firmness, and Leeb Firmness

Conversion Dining table 1 gifts study throughout the Rockwell C stiffness variety towards matchmaking certainly one of Brinell firmness, Vickers hardness, Rockwell firmness, Rockwell superficial firmness, Knoop stiffness, and you can Scleroscope firmness out-of non-austenitic steels plus carbon, alloy, and you will device steels regarding due to the fact-forged, annealed, normalized, and you may quenched and you will tempered standards provided he is homogeneous.

Such hardness conversion relationships are intended to apply including for the following: nickel-aluminum-silicone polymer specimens accomplished to industrial factory standards for hardness comparison, since the whole list of this type of metals off their annealed to help you the heavily cold-worked otherwise age-hardened standards, and additionally the intermediate standards

Conversion process Dining table 2 gift ideas study regarding Rockwell B firmness diversity toward dating among Brinell stiffness, Vickers firmness, Rockwell stiffness, Rockwell shallow firmness, Knoop firmness, and you will Scleroscope firmness from low-austenitic steels along with carbon dioxide, metal, and you will product steels regarding the since the-forged, annealed, stabilized, and quenched and you will tempered standards so long as they are homogeneous.

Conversion process Desk 3 gift suggestions studies towards dating among Brinell firmness, Vickers stiffness, Rockwell stiffness, Rockwell low hardness, and you will Knoop stiffness from nickel and you may large-nickel alloys (nickel stuff over fifty %).

Conversion Table cuatro gift ideas investigation towards relationships certainly Brinell stiffness, Vickers firmness, Rockwell hardness, and you can Rockwell low firmness out-of cartridge brass.

Transformation Desk seven gifts study on the relationship among Brinell stiffness, Vickers firmness, Rockwell firmness, Rockwell superficial hardness, and Knoop stiffness away from copper.

Sales Desk 8 presents studies with the relationship certainly one of Brinell stiffness, Rockwell hardness, and you can Vickers firmness of alloyed light iron.

Conversion process Dining table 9 gift ideas research into matchmaking one of Brinell firmness, Vickers firmness, Rockwell stiffness, and you may Rockwell low hardness regarding wrought aluminum situations.

Transformation Dining table ten presents analysis on the Rockwell C stiffness diversity for the relationships certainly Leeb (Form of D) hardness, Brinell firmness, Vickers firmness, and you will Rockwell hardness out of non-austenitic steels and additionally carbon dioxide, metal, and you may product steels regarding since the-forged, annealed, normalized, and quenched and you will tempered criteria provided they are homogeneous.

Conversion process Table 5 gifts data for the relationship anywhere between Brinell hardness and you can Rockwell B firmness off austenitic stainless plate regarding annealed reputation

Certain sales philosophy showed here had been extracted from desktop-produced contours from genuine attempt data. Really Rockwell firmness wide variety are presented to new nearest 0.1 otherwise 0.5 hardness count permitting right reproduction of those contours.

Annex A1 – Annex A10 incorporate equations to alter from 1 firmness measure so you can several other. The newest equations given from inside the Annex A1 – Annex A9 was in fact install throughout the studies when you look at the Tables 1 to nine, respectively. The latest equations offered when you look at the Annex A10 was indeed setup during the time new Leeb hardness decide to try are created (find Appendix X2). The information in the Dining table ten was determined regarding Annex A10 equations.

Transformation out-of firmness philosophy is going to be put on condition that it is impossible to attempt the materials under the standards specified, of course conversion process is established it needs to be done with discretion and you may under controlled requirements. Each kind off firmness try was at the mercy of particular mistakes, in case safety measures is actually very carefully observed, brand new reliability out-of stiffness indication produced to the tool of your own indentation style of would-be discover comparable. Differences in awareness from inside the listing of certain firmness measure (including, Rockwell B) may be more than anywhere between several other bills otherwise sorts of tools. The new sales philosophy, if or not on tables or computed on equations, are merely calculate and may getting incorrect having certain application.

It in the world important was created according to globally acknowledged prices with the standardization established in this new ent of Internationally Conditions, Guides and you will Pointers awarded because of the Industry Change Team Technical Barriers to Change (TBT) Panel.
