Drinking water Testing

Drinking water Testing

Drinking Water and fresh air are the unavoidable reasons for life. More than 70% of human body is composed by water. But unfortunately, only 3% of water available across the globe is fresh water and only half of that is available to humans. In developing countries like India, population growth combined with industrial development is hard pressing on water demand resulting in the shrinkage of water table.

Soil Testing

Soil Testing

Chloride Content:

The effect of chloride concentration in soil on corrosion of reinforcing steel was evaluated by measuring corrosion potentials and corrosion current density.
Concrete in contact with soil bearing high levels of chloride could suffer from early ingress of this chloride, leading to corrosion of any embedded reinforcement. Measures of chloride levels in soils are often taken to check whether the soil will be suitable to be used adjacent to concrete.
Test Method: IS: 4032-1985

Electrical Resistivity:

Electrical resistivity of the soil can be considered as a proxy for the spatial and temporal variability of many other soil physical properties (i.e. structure, water content, or fluid composition). Because the method is non-destructive and very sensitive, it offers a very attractive tool for describing the subsurface properties without digging.
Test Method: IS: 15736-2007

Polymers & Rubbers Testing

Polymers & Rubbers Testing

Ash content:

This test helps in determining the amount of fillers in a specimen after the polymer has been burned off and suitable for the determination of the ash content of rubber compounding materials. The test methods may be used for quality control, product acceptance, or research and development.
Test Method: ASTM D2584, D5630, ISO 3451

Bulk density:

This test helps in determining the weight per unit volume of material. The bulk density (morphology) of the rubber contributes significantly to the binder’s performance and is used as a property in the specification of the rubber.  This test method provides a measure of the crumb rubber’s bulk density.
Test Method: ASTM D1895B

Compression set under constant deflection:

This test helps in determining the ability of elastomeric material to maintain elastic properties after prolonged compressive stress. The set test is used to determine the quality of rubber compounds and their applicability to certain types of usage.
Test Method: ASTM D395 B

Transformer Oil Testing

• • Transformer Oil Testing

Transformer Oil Testing

Transformer oils are subject to electrical and mechanical stresses while a transformer or other electrical distribution equipment is in operation. The analysis of insulating oils provides information about the oil, but also enables the detection of other possible problems, including contact arcing, aging insulating paper and other latent faults and is an indispensable part of a cost-efficient electrical maintenance program.

Though the failure risk of a transformer and other oil-filled electrical equipment is small, when failures occur, they inevitably lead to high repair costs, long downtime and possible safety risks. By accurately monitoring the condition of the oil, suddenly occurring faults can be discovered in time and outages can potentially be avoided.
