NG-RockGen Rockwell Hardness tester is ASTM E18 standard. ASTM E18 is the industry standard for Rockwell hardness testing of metallic materials. This specification includes both theory and standard practice statements. For those companies Nadcap accredited in heat treat where the AC7102/5 for hardness and conductivity testing is included, an additional layer of requirements come into play. ASTM E18 lists three types of verification testing: direct verification, indirect verification, and daily verification.
Direct verification is performed when the machine is purchased new from the manufacturer, when the indirect test fails, or when any adjustments, modifications or repairs have been made to the machine that could affect any testing variables. Indirect verification is performed annually, when a new machine is received and installed, or when a machine is moved. Daily verification is performed each day prior to using the hardness tester, when the anvil, test force, or indenter is changed.

Here are a few of the most important factors to consider to ensure an accurate conclusion from a hardness test.
Manually Operated Hardness has many features and functions. The high gloss and scratch resistant surface on this unit will keep it looking new for many years. The dial gauge can read the hardness value directly, which makes it resistant to minor damages. The indicator has a sensitive response and is accurate in displaying the hardness value. The loading wheel is easy to adjust with the three loading test forces based on the hardness scale. This model does not require electrical power. To obtain your personal quote, click here.
There are four main hardness tests, each with their own set of benefits and requirements. There are different standards for these tests, which explain the procedures and application of the hardness test in detail. When selecting a hardness test method, important considerations include:
Electronically Controlled Hardness Tester offers various features and functions. The glossy and scratch-resistant surface keeps the device looking new after years of use. Molded shell with stable structure resists minor damage. This electronic tester is used for thin parts and metal surfaces. The test load, holding time and unloading are automated to eliminate the human factor. The dial indicator directly reads the hardness value. The indicator has a sensitive response and accurately shows the hardness value. For your personalized quote, click here.
Rockwell hardness testers are used for trials that calculate indentation rigidity in metal. Most indentation hardness tests are used to determine the measure of deformation that happens when the metallic substance is penetrated with a certain category of indenter. A pair of forces with specific rates and dwell times is applied to the test material during Rockwell hardness tests. The hardness of the substance is determined by the contrast between the indenter’s depth at two specific intervals during the testing process. The hardness value is calculated by implementing a formula that was designed to yield a value that falls within a pre-determined span of numbers that makes up the Rockwell hardness scale.
The main application for NG-RockGen – Analogue Series Rockwell Hardness Tester – Manual and Electronic Models includes the following: chilled steel, hardened and tempered steel, annealed steel, casting, malleable cast, hard alloy, hardened steel plate, aluminum alloy, bearings steel.

There are two primary ways to test the hardness of a material – scratch testing and indentation testing. Indentation testing can only be used on materials that undergo plastic deformation, such as metals and thermoplastic polymers. The scratch test is therefore used for brittle materials such as ceramics. The hardness of a material can be determined using Moh's hardness scale, which ranks a material based on a list of standard materials of known hardness. The scratch resistance of the material is ranked on a scale between the material it just scratches and the material that it fails to scratch. There are many ways to measure the hardness of a material by indenting it. The three most common tests used to measure hardness are the Brinell test, the Vicker’s Diamond test, and the Rockwell test.

There are two test forces for NG RockGen Tester – preliminary test force and total test force. Preliminary test force is 10kg (98N) while total test force is 60kg (588N), 100kg (980N), 150kg (1471N). If you have any other question or are looking to obtain a quote, click here.
The Rockwell hardness test method, as defined in ASTM E-18, is the most commonly used hardness test method. You should obtain a copy of this standard, read and understand the standard completely before attempting a Rockwell test. Preliminary test loads (preloads) range from 3 kgf (used in the “Superficial” Rockwell scale) to 10 kgf (used in the “Regular” Rockwell scale). Total test forces range from 15kgf to 150 kgf (superficial and regular) to 500 to 3000 kgf (macrohardness).
Test Method Illustration
A = Depth reached by indenter after application of preload (minor load)
B = Position of indenter during Total load, Minor plus Major loads
C = Final position reached by indenter after elastic recovery of sample material
D = Distance measurement taken representing difference between preload and major load position. This distance is used to calculate the Rockwell Hardness Number.
NG RockGen – Analogue Series Rockwell Hardness tester has the following three ranges. First, HRA: 20-88, second, HRB:20-100, and finally HRC:20-70. If you want more information about NG-RockGen – Analogue Series Rockwell Hardness Tester or If you want to obtain a personal quote, click here.

The Rockwell hardness test provides the fastest and most accurate way to test the hardness of a material and takes place over three stages. In stage one, a load of force is applied to the material being tested for a short period of time, commonly using a diamond or ball indenter to apply the force. In stage two, the force being applied is increased and is called the major load. In stage three, the major load is removed from the material being tested and the original smaller load of force is applied once again. After this process is complete, the resulting indentation is measured and used to calculate the difference between the final and original indentation depths. The force applied using the indenting tool typically ranges between 15kgf and 3000kgf. There are several different Rockwell hardness scales, each identified by the use of a letter including A, B, C, D, E, F, G, H, and K.
At NextGen, our NG-RockGen Analogue Rockwell Hardness Tester can test the following 6 superficial scales: HR15N, HR30N, HR45N, HR15T, HR30Tand HR45T.

The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale. The Rockwell hardness test can be conducted on several various hardness testers. All testers, however, fall under one of three categories. Bench model hardness testers can be found either in a digital or analog model. Digital bench models utilize a digital display and typically take more technical training to be able to operate. Other testers are portable, and all portable testers will come in a digital model including a digital results screen similar to that of the bench digital model.
