Quality Test


PARS POLYMER test facilities are equipped with modern laboratory equipments such as :



Measuring the hardness (firmness) of a product determines whether that will be suitable for a particular product in producing the desired properties.It determine the penetration depth of a standard cone under defined conditions. Cone angles can range from 15–90°;



Melting point is defined as the temperature at which the solid phase exists in equilibrium with its liquid phase. Drop melting point, Test Method-D127, is often used to measure the melting characteristics of petrolatum’s and other high viscosity petroleum that covers the determination of the drop melting point of petroleum wax and other micro crystalline wax;



ASTM-1500 Color Scale is widely used for the grading of petroleum products such as lubricating oils, heating oils and diesel fuel oils. Mineral oils are constantly checked for color during processing in order to establish when they have been refined to the required grade. Color is also used as a means of confirming that the correct oil or fuel is being used for its intended use and that no contamination or degradation of quality has occurred

ASTM-D1500 is a single number, one dimensional, color scale ranging from a pale straw through to a deep red in sixteen steps (0.5 – 8.0 units in increments of 0.5 units). Other petroleum products that do not fall within the scope of ASTM D1500 such as white spirit, petroleum wax and kerosene may be graded using the Saybolt test ASTM-D156 or IP17;


SPECTROPHOTOMETER (Light Absorption & Poly cyclic aromatic hydrocarbon)

Spectrophotometry is a method to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution. Every chemical compound absorbs, transmits, or reflects light over a certain range. Spectrophotometry is a measurement of how much a chemical substance absorb or transmit;


Oil Content in Paraffin Wax Testing Equipment by ASTM-D721 is apply to ASTM D721 Standard Test Method; ASTM D721 is suitable to determine the oil content of All Waxes , the congealing point of which is higher than 30 °C and the oil content of which is not more than 15%.;


An instrument that determines the flash point of a sample, which is the temperature point at which the sample vaporizes to another composition state in the air that can be ignited. At that moment, the flash point apparatus can determine and measure the vapor pressure change in which this occurs, also known as the lowest limit of flammability. Therefore, vapor concentration can be determined by temperature;


Viscometers are used to determine the viscosity of a fluid under specific flow and atmospheric conditions. Viscometers are used for a range of applications including product development, research and quality control;
