ISO/IEC 17025:2017 (NABL) Certification for Soil and Rock
Soil and Rocks
When it comes to architecture or civil engineering, the first and foremost element that is need to erect a structure is the land. The land comprises of soil and rocks. The properties of the soil and rocks determine the approach to be taken by civil engineers to erect the structure. For these a deep study of both is required.
Soil
As soil is the main component for the land, it is essential to study, describe and classify the soil according to its properties so that a right approach for construction could be adopted. To describe and classify the soil, there must be a formal system that could describe the various materials that are found in soil.
Description of spoil refers to a detailed statement that can describe the nature and properties of the soil. This is done by taking a sample from the site and analyse it in a laboratory. This can be done with the aid of visual examination, simple tests, and observation of site conditions, historical geology and several other factors.
The classification of soil refers to separation of the soil in to different types and groups. Each group has same properties, Characteristics, and behaviour. The classification of the soil for engineering purposes is mainly done on the basis of its mechanical properties such as strength, permeability, shear ability and stiffness. The class or group of the soil is used in the description.
The range of the grains of the soil has a significant impact on the properties of the soil. The larger the size of the grain, lesser the ability of soil to bind. According to grain size, there are five type of soils that are Clay, Silt, Sand, Gravel and cobble boulder. Sand grains are basically the broken rock particles that are formed due to physical weathering process whereas the clay grains are formed as a result of chemical weathering of the rocks.
Rocks
Rocks that are found in soil are also tested for engineering purposes as they also play an important role in stability of the structure. Hence the testing of rocks is also done. There are different factors of rocks that are tested in laboratories. The lab testing is done to determine the degradation and disintegration of the rock material with the course of time. Common laboratory tests that are conducted on the rocks include strength tests. In strength tests there are different tests such as Point load strength test, compressive strength tests, creep test, tensile strength test, direct shear, permeability, durability and so forth. These tests are very helpful for the civil engineers in deciding the right approach for the structure construction.
One thing that needs to be kept in mind is that the properties of the soil and rocks have a great impact on eth stability of the structures erected on them, hence it is essential that the tests conducted on the samples are capable of giving the most accurate testing data. Any negligence can cost a lot in terms of money and lives. To ensure the test accuracy, one can ensure that the tests are conducted in a laboratory that is certified by ISO 17025:2017 and has NABL accreditation. These are the standards that must be followed by the labs for conducting tests to ensure accurate testing data.
