Berlia Electricals have a vision to provide best quality products, extruded from virgin material. We at Berlia Electricals follow quality control process as per the instructions of the Bureau of Indian Standards.
WE HAVE IS : 4984: 1996 AND IS : 14333:1996 AFFILIATED BY BIS

Adoption of quality management system is one of our strategic decisions, design and implementation of our quality management system is influenced by our organizational environment, changes in the environment, risks associated with that environment, our varying needs, our objectives, our products & our processes.

The material used for the manufacture of pipes should not constitute toxic hazard, should not support microbial growth and should not give rise to unpleasant taste or odour, cloudiness or discoloration of water. We obtain a certificate to this effect from the manufacturers of the raw material used.

The internal and external surfaces of the pipe are kept smooth, clean and free from grooving and other defects. The ends of the pipes are cleanly cut square with the axis to within tolerance given as per IS standards.

A number of tests like Measurements Test, Density Test, Short Term and Long Term Hydrostatic Pressure Test, Effect on Water, Reversion Test, Opacity Test, and Resistance to External blows, Vicat Softening Temperature, Sulphated Ash Content Test are applied for the purpose of checking overall strength and performance of the product. Each length/coil are clearly and indelibly marked in ink/paint or hot embossed on white base at intervals.

The Indian/International standards followed at Berlia Electricals Pvt. Ltd. promotes the adoption of a process that may develop, implement and improve the effectiveness of a quality management system, to enhance customer satisfaction by meeting customer requirements. At Berlia, we consider and expect continual improvement in the quality management system in accordance with the methodology known as "Plan-Do-Check-Act" The quality control procedure is thereby applied at regular intervals to ensure the best quality delivered.

Tests as per Bureau of Indian Standards
Measurements Test
This test method covers the determination of diameter, wall thickness, and length dimensions of thermoplastic pipe. Included are procedures for measurement of the inside diameter of pipe intended to be joined by internal fittings, measurement of the average outside diameter for roundable pipe where out-of-roundness is not of primary concern, out-of-roundness measurement and measurement of the average outside diameter of non-roundable pipe, and for determining length and straightness.

Short Term and Long Term Hydrostatic Pressure Test
A hydrostatic test is a way in which leaks can be found in pressure vessels such as pipelines and plumbing. The test involves placing water, which is often dyed for visibility, in the pipe or vessel at the required pressure to ensure that it will not leak or be damaged. It is the most common method employed for testing pipes and vessels. Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then continually re-qualified at regular intervals using the proof pressure test which is also called the modified hydrostatic test.

Reversion Test
Residual stresses inherent in the extrusion of plastic pipe products may have long term adverse effects on product performance. In particular, ESCR or environment stress cracking is accelerated in pipes with high frozen in internal stresses. Longitudinal Reversion Test is a method of determining the level of internal stresses in pipes.
