Foundrax are able to supply a wide range of standard and bespoke adaptors in order to either retrofit their Model 134 portable Brinell test head, ATH1 closed loop non optical Brinell test head and ATH2 optical fully automatic closed loop Brinell test heads to a customer’s existing Brinell hardness testing frame or alternatively for fitting by the customer to a bespoke frame.

Foundrax are able to supply a wide range of standard and bespoke anvils for use in any Brinell hardness tester.

These are for comparison purposes to determine degree of operator accuracy in manual microscope measurement.

These are steel blocks containing 5 Reference Indentations made with a 10mm ball in the range 2.40-6mm and 5 Reference Indentions made with a 5mm ball in the range 1.30-3mm. These measuring ranges cover all Brinell scales using 10mm and 5mm Brinell balls.

The weakness of the Brinell test is in the measurement of Brinell indentations. With the exception of the very few acceptable automatic systems this applies to all machines and microscopes to varying degrees.

The problem lies in the fact that the start and finish of the measurement depends on a subjective judgement of where the edge of the indentation is. If one person measures the diameter of an indentation as being "A" and another measures it as being "B" who is to say who is right? Because they are made in a traceable Brinell Calibration machine, the measurements of the indentations on Foundrax Reference Indentation Reading Blocks are correct by definition and represent the standard of measurement to which operators should aspire.

Each Reference Indentation has been measured in accordance with BS EN ISO 6506 in a master Brinell Calibration Microscope which is traceable to National Standards and its mean diameter is given on the accompanying certificate.

Foundrax Reference Indentation Reading blocks are supplied in protective boxes with official UKAS certificates of calibration.

By measuring each indentation it is possible to determine the uncertainty of measurement for each operator, and if necessary to train them to measure correctly and to tighter limits than they have been used to.

The mean diameters of the Reference Indentations are given on the Certificate and not on the Block. To avoid being influenced by the true measurements the person measuring the indentations should be asked to write down the measurements and should not be told what the actual measurements are.

It can then be seen whether his measurements are large or small (and by how much) consistent, inconsistent etc.

When disputes over Brinell hardness arise it is possible to find which party is making the truer measurements.

Foundrax Brinell Reference Indentation Reading Blocks may be used for the Indirect Verification of Brinell microscopes to BS EN ISO 6506.

Foundrax are able to supply UKAS certified Tungsten Carbide Brinell indenters in 1mm, 2.5mm, 5mm and 10mm.

Foundrax were the first manufacturer in the UK to be officially recognised for the manufacture of Brinell hardness reference blocks and continue to lead the field for quality.

Foundrax UKAS certified Brinell hardness reference blocks conform to ISO 6506 and ASTM E10 and our accredited uncertainty of measurement puts us at the top of the industry.

These 173cm surface area Brinell blocks are supplied with marked grids which make them easier to use, give the correct spacing between indentations and enable indentations to be recorded. A record card is supplied.

A variety of hardness ranges are available as standard allowing the user to select a block appropriate to their calibration and verification requirements.

Notes:

• All blocks certified to BS EN ISO 6506-3 and ASTM E10
• All blocks supplied with official UKAS certificate of calibration unless requested otherwise
• Blocks in scales HB10/3000 to 5/250 supplied 173cm² surface area
• All blocks in steel except where marked A (aluminium)
• Standard hardness ranges are marked in bold
• Advise hardness range & hardness scale required e.g. 140-169HBW 10/3000

Foundrax UKAS certified Rockwell and superficial Rockwell hardness reference blocks conform to ISO 6508 and ASTM E18 and our accredited uncertainty of measurement puts us at the top of the industry.

Rockwell blocks are available with an optional grid giving the user the opportunity to optimise the use of space without the risk of accidentally placing indentations too close together as well as to demonstrate good practice to auditors etc.

All of our blocks feature a mirror finish for clarity and ease of use
