Different tests are performed on natural stone to determine its quality, durability, and suitability for different applications. Some of the most common tests are:

1. Water Absorption Test: This test measures the amount of water that a stone absorbs in a given amount of time, and is used to determine the porosity and permeability of the stone. Stones with high water absorption rates are more likely to stain, crack, and deteriorate over time.
2. Breaking Strength Test: This test measures the amount of force required to break a stone, and is used to determine its strength and resistance to impact. Stones with high breaking strength are more suitable for high-traffic areas and high-stress applications.
3. Scratch Resistance Test: This test measures the ability of a stone to resist scratching and scuffing, and is used to determine its durability and resistance to wear and tear. Stones with high scratch resistance are more suitable for flooring, countertops, and other high-use surfaces.
4. Slip Resistance Test: This test measures the coefficient of friction of a stone, and is used to determine its slip resistance and safety in wet or slippery conditions. Stones with high slip resistance are more suitable for flooring, steps, and other surfaces that are likely to get wet.
5. Stain Resistance Test: This test measures the ability of a stone to resist staining from common substances such as oil, wine, and other liquids. Stones with high stain resistance are more suitable for countertops, flooring, and other high-use surfaces.

These are just a few examples of the different tests that are performed on natural stone. The specific tests that are required will depend on the intended use, location, and design style of the space, as well as the properties of the different types of stone that are available. The results of these tests help to determine the quality, durability, and safety of natural stone, and to ensure that it is suitable for its intended use and location.
