Tiles, Marbles, Granite, Refractory bricks & Paving blocks

Welcome to Middle East testing services. A leading services provider for Marble Testing Labs and evaluation of tiles, marbles, granites, refractory barks and paving blocks and all the construction materials or the manufacturers piece of materials we have wide range of test like water absorption test, Hardness test, Modulus Rapture test, Dimension testing, Thermal shock test, flooring tile test, frost resistance test, chemical resistance test, breaking strength test and so on. 

Tiles are the construction materials and their major application is for covering the floors, roofs, walls, table tops and similar object tiles are categorized on the basis of the applied manufacturing processes and their application METS Lab provide testing facilities for all type of rules as per various national and international standards. Ceramics are such things as tiles, fixtures, etc. Ceramics are mostly used as fixtures or coverings in buildings. Ceramic floors, walls, counter-tops, even ceilings. Many countries use ceramic roofing tiles to cover many buildings. Ceramics used to be just a specialized form of clay-pottery firing in kilns, but it has evolved into more technical areas. Some of the routines test that we conduct for tiles are dimension, flexural strength, surface quality, breaking strength, abrasion resistance, compressive strength, impact resistance, thermal expansion, chemical resistance, bulk density, staining resistance


Granites are one of the most used manufacturing/construction materials in different kind of industries. With a sharp increase in grant demand at local, national and international level, the factor of quality testing has become a prime concern for both buyers and sellers. There are a few granites quality testing process at the national and international level that assay the quality of a granite product ready to be sold in the competitive market. Globally, there are about 300 granite varieties. There varieties are famous for their unique colour, texture, and structure. The granite processing industry has developed over the years, so are the standards of testing water absorption, gravity, thickness, density, strength, flexure, rupture, abrasion and friction resistance are the prime factors considered for successful testing of granite stone products. Physical properties of granite like porosity, permeability, thermal stability, coefficient of expansion, Variegation and hardness matter the most in the field test to find out granite quality.

The tests method we conducts are

Water absorption

The amount of water that a refractory can absorb is measured by the water absorption test. The results of water absorption tests are used for quality assurance.
Test Method: ASTM C 97-2009, ASTM D 570

Mohs Hardness

This test helps in determining the hardness of rock. Because granite is a rock composed of multiple minerals, only crystals of specific minerals within the granite would be tested for hardness.
Test Method: ASTM C1895-19

Modulus Rapture

The modulus of rupture (MOR) is the maximum surface stress in a bent beam at the instant of failure. One might expect this to be exactly the same as the strength measured in tension, but it is always larger because the volume subjected to this maximum stress is small, and the probability of a large flaw lying in the highly stressed region is also small.
Test Method: ASTM C 99-2009

Dimension Testing

This test is done to check the dimensional stability of the rock.
Test Method:  ASTM C 625, ASTM C 616, ASTM C 629, ASTM C503

Thermal shock test

Thermal shock is the name given to cracking of product as a result of rapid temperature change. Glass and ceramic objects are particularly vulnerable to this form of failure, due to their low toughness, low thermal conductivity, and high thermal expansion coefficients. However, they are used in many high temperature applications due to their high melting point.
Test Method: ASTM C 1525-04, EN-104, ISO 10545 

PVC Flooring tile

PVC Flooring provides dust-free, noise absorbing, resilient, non-porous, decorative surface. It shall consist of a thoroughly blended composition of thermoplastic binder, filler and pigments.
Test Method: ASTM F2982

Frost Resistance

Ceramic tile frost resistance is defined as the ability of ceramic tile to withstand freeze/thaw conditions with minimal effect. The frost resistance of ceramic tile is dependent on the tile’s porosity and water absorption levels. Frost damage can occur when the variety of ceramic tile absorbs moisture through its pores, causing the water to freeze internally when temperatures drop. Since water expands when it freezes, tension is then exerted inside the body of the ceramic tile. This internal pressure may become high enough to cause cracks in the ceramic tile.
Test Method: ASTM C 666M, BS EN 12371

Chemical Resistance test

This test is done to determine the ability of the grade of granite used by a1-safetech to resist chemical attack.
Test Method: ASTM C267-01

Breaking Strength

Rocks are considerably weaker in tension than in compression. Characterizing tensile strength of rocks thus is of great importance in many engineering and geophysical applications. Tensile strength is defined as the failure of stress.
Test Method: ASTM D 5034

Another main building material testing id Brick Testing. We test and certify bricks using below methods

Apparent Porosity and Density

This test helps in determining the porosity and density of bricks to be used for construction of load bearing walls. The method involves dimensional measurement and mass to determine density, followed by measuring the increase in mass when soaked in water for a standard period.

Water Absorption

The amount of water that a brick can absorb is measured by the water absorption test. There is no distinct relationship between water absorption and the water-tightness of walls. The results of water absorption tests are used by the brick manufacturer for quality assurance.

Permanent Linear Change

This test helps in determining the permanent linear change of refractory brick when heated under prescribed conditions, which will measure any potential shrinking when used for load bearing walls.

Abrasion Resistance

The abrasion resistance of a refractory material provides an indication of its suitability for service in abrasion or erosive environments.

Creep Test

Creep in compression (CIC) refers to the percent of shrinkage of a refractory test piece under a constant load and exposed to a constant high temperature over a long period of time.

Modulus of Rapture

The modulus of rupture (MOR) is the maximum surface stress in a bent beam at the instant of failure. One might expect this to be exactly the same as the strength measured in tension, but it is always larger because the volume subjected to this maximum stress is small, and the probability of a large flaw lying in the highly stressed region is also small.

Fly ash / Lime Brick

This test helps in determining the strength of brick

Stainless Steel Testing

In neutral and corrosive environments, stainless steel is highly desired for its excellent properties. However, it is prone to flaws so it must be thoroughly inspected. Most of the flaws can be detected in the heat-affected zone around the welded joints.  Stainless Steel Testing helps us to understand and quantify whether a specific material or treatment is suitable for a particular application. All stainless steels have a high resistance to corrosion. Low alloyed grades resist corrosion in atmospheric conditions; highly alloyed grades can resist corrosion in most acids, alkaline solutions, and chloride-bearing environments, even at elevated temperatures and pressures. Stainless Steel testing ultimately proves the strength, hardness and quality of the final material.
