Barcol Hardness Test

Barcol Hardness Test

A portable, hand-held instrument like the PosiTector BHI, which consists of an indication device and an indenter, is used to measure barcol hardness.

The Model 934-1, which was first developed more than 75 years ago, has been updated as the PosiTector BHI Barcol Hardness Impressor. Operator mistake is reduced to a minimum by the digital hardness tester. Although these directions were designed for the PosiTector BHI, they can be applied to any Barcol Hardness tester model.

Following are some of the benefits of the Barcol Hardness Test : 

• Each digital reading’s digital readout is recorded in memory for further analysis and reporting.
• Trends and average values are simple to spot thanks to the on-screen statistics display.
• After the measurement is finished, download readings to a PC or Mac via the built-in USB connector.
• When assessing a material’s hardness, the PosiTector BHI has an on-screen timer.
• Periodic Readings
• When measuring, average, standard deviation, and minimum or maximum hardness information are updated and continuously presented on the screen.
• When readings exceed user-specified limits, the PosiTector BHI’s HiLo Alarm enables the gauge to vocally and visually warn the user.
• After the required number of readings are stored, the Auto Sub-Batch in the PosiTector BHI Advanced model automatically creates a new sub-batch.

Conclusion:

The Barcol hardness test is a useful and widely used method for measuring the hardness of non-metallic materials such as plastics, composites, and reinforced fibreglass. This test uses a handheld instrument with a pointed indenter that is pressed into the material, and the hardness value is read from a dial or digital display.
