What is BS EN 523 — Steel strip sheaths about?
BS EN 523 is an international standard that covers the terminology and other aspects of steel strip sheaths for prestressing tendons.
BS EN 523 is applicable to uncoated cylindrical steel sheaths with a corrugated profile and with a nominal internal diameter of up to 130 mm and their connectors (couplers) which are assembled to form ducts for prestressing tendons in post-tensioned prestressed concrete structures.
BS EN 523 covers technical specifications such as related terms, classification, requirements, technical documents, delivery tickets, marking and labelling criteria, measures for storage, and procedures to evaluate conformity for checking the quality of steel strip sheath.
Note 1: BS EN 523 is only applicable to sheaths and connectors made of interlocked or welded steel strips.
Note 2: BS EN 523 does not cover plastic sheaths.
Note 3: The seals required between sheaths and couplers are not covered by BS EN 523.

Why should you use BS EN 523 — Steel strip sheaths?
Steel strip sheaths are a steel strip covering, often made from alloys such as Stainless Steel, used for protection from heat attacks or electrical shocks. These sheaths are widely used for many applications in the metal and electrical industries.
BS EN 523 provides you with all the technical specifications for steel strip sheaths used for prestressing tendons, which helps the users to understand the standard qualities such as flexural behavior , flexibility, leak-tightness, etc for the steel strip sheaths. It also covers the requirements for the connectors and stiffeners, as well as the procedures for the evaluation of conformity which contributes to establishing factory production control with efficiency.
Users of BS EN 523 can also check the technicalities related to documentation, delivery tickets, marking and labelling of the steel strip sheaths that are in compliance with international standards.
Thus, BS EN 523 provides you with comprehensive information useful for checking the high quality of steel strip sheaths for prestressing tendons with minimum or no manufacturing defects.
