EN 993-3 Test Methods for Dense Shaped Refractory Products - Test Methods for Carbon Containing Refractory Products

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 993-3 testing. This European standard specifies test methods for oxide-based and carbon-containing refractory products. Carbon can be added in the form of an element such as graphite or as carbonaceous materials such as pitch, tar or resin.

EN 993-3 is a European standard that specifies test methods for refractories containing carbon, which are refractory products containing carbon as an essential component. These products are used in a variety of high temperature applications such as steelmaking and other industrial processes.

The standard covers three different test methods for carbon containing refractories:

• Determination of Visible Porosity: This method measures the total volume of open pores in a test sample. The sample is weighed in air and then immersed in water to determine its volume and the weight difference is used to calculate the apparent porosity.
• Determination of Bulk Density: This method measures the density of a test sample, including both solid and pore volume. The sample is weighed in air and then immersed in water to determine its volume, and the weight difference is used to calculate the bulk density.
• Determination of Cold Crush Strength: This method measures the ability of a test sample to withstand a compressive load at room temperature. The sample is placed in a testing machine and subjected to a compressive force until it breaks, and the load at which the fracture occurs is recorded as the cold crush strength.

The standard provides detailed procedures for each of these test methods, including preparation of test specimens, calibration of test equipment, and calculation and reporting of test results. It also specifies the requirements for test samples, including their size and the number of samples to be tested.

In general, EN 993-3 provides a standardized set of test methods for carbon containing refractories that are important for ensuring consistent quality and performance in high temperature applications.
