BS 2751 is a British Standard that specifies the requirements for general purpose acrylonitrile-butadiene rubber (NBR) compounds. NBR is a synthetic rubber that is known for its excellent resistance to oil, fuel, and other chemicals. It is also known for its good mechanical properties such as high tensile strength and high abrasion resistance. This makes it an ideal choice for a wide range of industrial applications, including gaskets, seals, hoses, and other products that require a high level of performance in harsh environments.
BS 2751 covers the properties that are required for NBR compounds to be considered general purpose. These include things like tensile strength, elongation, compression set, and hardness. The standard also specifies the requirements for the raw materials that are used to make the compounds, including the type and amount of the various ingredients that are required. This ensures that the compounds are of a consistent quality and that they will perform as expected in the intended application.
The standard also includes guidelines for the testing and inspection of NBR compounds, including the procedures that are used to measure the properties that are specified in the standard. This helps to ensure that the compounds meet the requirements set out in the standard, and that they will perform as expected in the intended application.
Overall, BS 2751 is an important standard that helps to ensure the quality and consistency of general purpose NBR compounds. It provides a set of guidelines and requirements that manufacturers must follow in order to produce compounds that meet the needs of their customers and that will perform well in a variety of industrial applications.
