Quality Control Setup

Raw Material Inward process & Testing BRIs rubber raw materials are tested under strict observation on basis of chemical-analytical and physical-mechanical measurements resulting mostly in physical constants that can be used to determine our department the purity of the raw materials, such as determination of melting temperature, Specific Gravity, contents of moisture, dry matter, ash or volatile substances, determination of viscosity in liquid samples, active ingredient content, heavy metal content (rubber poisons), refraction index, acidity figures etc. Our in-house laboratory qualifies to follow strict methodology to use in quality control for input of raw materials, which must correlate with raw material purity. Broadly, materials which are being tested are Elastomers, Reclaimed products, Fillers, Additive Agents, Curing Agents, Carbon, Oils, etc. The equipment used to determine respective values for all the samples and inward materials are :

  • Specific Gravity meter (Density meter)
  • Weighing scale (in grams)
  • Electric Furnace
  • Oven
  • Viscometer, etc.

The product specification and the acceptance / rejection criteria, such as acceptable quality level and unacceptable quality level has been predefined by BRIs technical panel for making a decision to accept or reject a lot. Any deviation from the written specifications, standards, sampling plans, test procedures or other laboratory control mechanisms are recorded and justified. A certificate of Analysis is documented for each sample lot drawn from the batch. All the products properties are crosschecked with the certificate issued by supplier. All these documents are kept to revive as and when information is needed. Once materials are checked to its said property, it is then entered into the system and stock is added to the existing ones. If rejected, materials are sent back to its source. Accepted entries are then recorded in as Inward Slip, which states that now the purchased materials are eligible to be used by the Production Department. BRIs Quality control under GMP headed by Material Indent Department share a common goal of assuring that the goods received are of highest purity during constant supply. Their constant effort is to make new sampling research, asking supplier to improvise the quality in a specified manner by sharing knowledge and improving our range of rubber products.
