BS 4F 123:1996 is a British Standard (BS) specification that pertains to woven nylon narrow fabrics used for aerospace purposes, specifically those made with nominally 235 dtex yarns. This standard provides detailed requirements and specifications for the manufacturing and quality control of such fabrics to ensure they meet the necessary standards for aerospace applications.
Here's a breakdown of the key components of this standard:
Title: The title of the standard is "Woven nylon narrow fabrics for aerospace purposes (nominally 235 dtex yarns)."
BS Number: The "BS 4F 123" is the unique identification code for this British Standard. It helps in referencing and identifying the specific standard.
Year of Publication: The "1996" in the standard code indicates the year when this standard was last updated or published. In this case, it's from 1996, so it may have been revised or updated since then.
The scope of the standard would outline the purpose and application of the standard. In this case, it specifies that it relates to woven nylon narrow fabrics used in aerospace applications and that these fabrics are made from nominally 235 dtex yarns.
Nylon Fabric Type: This standard likely specifies the characteristics and requirements for the woven nylon narrow fabrics, including dimensions, strength, durability, and other relevant properties. It may also include information on testing methods and quality control procedures.
235 dtex Yarns: The mention of "nominally 235 dtex yarns" indicates the specific yarn type or yarn count that should be used in manufacturing these fabrics. Dtex (decitex) is a unit of measurement for the linear density of yarn.
