Service Details:

Sigma is NABL certified, ISO / IEC 17025:2005 accredited laboratory delivering advanced solutions for assessing the consistency and suitability of Bitumen through various IS compliant test methods like Flash point, specific gravity, water content, paraffin wax, ductility test, Bitumen emulsion and more.

Bitumen Content
This test helps in determining the bitumen content. The apparatus needed to determine bitumen content are - Centrifuge extractor and Miscellaneous – bowl, filter paper, balance and commercial benzene.
Test Method : ASTM 2172, IS: 1202-1220

Bitumen Penetration
This test helps in determining the consistency of bituminous material & to assess the suitability of bitumen for use under different climatic conditions and various types of construction.
Test Method : IS:1203-1978

Flash Point
This test helps in determining the flash point and the fire point of asphaltic bitumen and fluxed native asphalt, cutback bitumen and blown type bitumen. The fire point is the lowest temperature at which the application of test flame causes the material to ignite and burn at least for 5 seconds under specified conditions of the test.
Test Method : IS:1209 – 1978

Specific Gravity
This test helps in determining the specific gravity of semi-solid bitumen road tars, creosote and anthracene oil. The principle is that it is the ratio of mass of a given volume of bitumen to the mass of an equal volume of water, both taken at a recorded/specified temperature.
Test Method : IS:1202 – 1978

Paraffin Wax
This test mainly used for food and other commodities (such as wax paper, crayons, candles, carbon paper) components and packaging materials, baking container coating materials, cosmetic raw materials, used in fruit preservation, and improve the rubber anti - aging and increased flexibility, electrical components, insulation, precision casting, etc., also can be used for synthesis of fatty acid oxidation. Crude paraffin oil content of more due mainly used in the manufacture of matches, etc. Adding polyolefin wax additive, its melting point is increased, adhesion and flexibility increase, widely used in moisture-proof, waterproof wrapping paper, cardboard, certain textiles, surface coating and candles production.
Test Method : IS:4654-1993

Loss on Heating
This test helps in determining the effects of heat & air during conventional hot-mixing on a thin film of semi-solid bitumen. The determination of the loss in mass is used to determine the volatility upon heating.
Test Method : IS:122-1978

Water Content
This test helps in determining the water in petroleum products, tars, and other bituminous materials by the distillation method.
Test Method : IS:1211-1978

Ductility Test
This test helps in determining the ductility of distillation residue of cutback bitumen, blown type bitumen and other bituminous products. The principle is: The ductility of a bituminous material is measured by the distance in cm to which it will elongate before breaking when a standard briquette specimen of the material is pulled apart at a specified speed and a specified temperature.
Test Method : IS:1208 – 1978

Bitumen Emulsion
This test helps in determining the dispersion of bitumen in water. However, in the same way as water and oil do not mix easily, water and bitumen together do not get on. Test Method:
