BS 3F 70 is a British guideline on heavy duty braided rubber cord. BS 3F 70 specifies requirements for heavy duty braided rubber cords in nine sizes from 5 mm to 26 mm in diameter.
BS 3F 70 guidelines outline about cords are suitable, when cut up into unit lengths, for the manufacture of shock absorber cord assemblies and for other aeronautical purposes.
NOTE 1 - The titles of the publications referred to in this standard are listed on the inside back cover.
NOTE 2 - The latest revision of an Aerospace Series standard is indicated by a prefix number.
BS 3F 70 on Heavy duty braided rubber cord is useful for:
Heavy duty braided rubber cord are used in the aerospace industry because they have high tensile strength and can be handled easily. BS 3F 70 provides you with the required characteristics of construction, diameter, rubber thread, braiding, and mechanical properties. As a manufacturer, this assists in the production of heavy duty braided rubber cord of high quality and durability.
BS 3F 70 assists you in improving the quality of heavy duty braided rubber cord by including all the qualities that make them best for use in aircraft. With compliance and obedience to BS 3F 70, you can demonstrate the reliability of your heavy duty braided rubber cord and build trust in their use throughout the aerospace supply chain.
