The term “hardness test block” usually refers to a compact, rectangular block of one type of material, usually a synthetic, that has been precision-cut to a specific size and geometry. The material is usually a harder material like a resin or a glass, which is why these blocks are called hardness test blocks. This is in contrast to a bar of material like a steel bar or a diamond bar, which are harder than most other materials and can therefore be used for hardness tests.
Hardness test blocks are used to test the hardness of an item by measuring the force required to break the block. The harder the material, the more force it takes to break the test block. They are usually made of a synthetic material, such as porcelain or quartz glass, so they can be more precise and uniform than natural material blocks.

Best Hardness Test Blocks Buying Guide
Before choosing the best hardness test block you should consider following options:
1. Number of Points: The first thing you should look for when choosing a hardness test block is the number of points it has.
The more points the block has, the higher the accuracy will be. If you are working with something that is harder to test, you can use a block with a higher number of points.
There are some options available that have up to 32 points.
2. Material: It is also important to look at the material the block is made of. Most of the time, these blocks are made from either a metal alloy or plastic.
The alloy blocks are the most accurate, but they are also the most expensive option. The plastic blocks are a lot cheaper.
The accuracy of these blocks may vary depending on the number of points, but it will never be as accurate as a metal block.
3. Graduations: The graduations on the block are very important. They will tell you the reading of the test piece.
Depending on the material, you can get blocks with graduations in either English or metric units.
If you are working with materials that are softer, then a block with smaller graduations will work better.
If the material is harder, then you should get a block with bigger graduations.
4. Size: The size of the block is also very important. There are some options that are very small, while others are quite big.
If you are working with small pieces of material, then a small block would work well. If the material you are working with is big, then you should get a bigger block.
Make sure you get a block that you can handle easily and that is portable. The last thing you want is a block that is too heavy for you to carry around.
5. Cost: The last thing you should look at when choosing a hardness test block is the cost.
There are some options that are very cheap, while others are quite expensive.
The price will depend on the material, accuracy, number of points, and graduations.
There are some blocks that have up to 32 points, but they are expensive. On the other hand, you can also get a cheap plastic block with only 2 points.
6. Warranty: Always check to see if the manufacturer offers some sort of warranty on the block.
If something goes wrong, you want to make sure you get your money back.
The warranty will depend on the materials, the accuracy, and the number of points.
