Full title and description

ISO 13950:2007/Cor 1:2008 — Plastics pipes and fittings — Automatic recognition systems for electrofusion joints — Technical Corrigendum 1. This corrigendum provides corrections and editorial amendments to ISO 13950:2007 (the international standard that defines automatic recognition methods used by electrofusion jointing equipment).

Abstract

ISO 13950:2007 specifies the characteristics of automatic recognition systems used with thermoplastic electrofusion fittings. It covers numerical recognition (bar codes, magnetic cards), electromechanical recognition (implanted-resistor connectors) and self-regulating systems that enable the controlled delivery of energy for electrofusion jointing of plastic pipes and fittings. The 2008 corrigendum corrects and clarifies items in the 2007 edition.

Scope

Applies to automatic recognition systems used with electrofusion fittings for thermoplastic piping systems. The standard is intended for fittings used in systems conveying gaseous fuels, water for human consumption (including raw water prior to treatment) and other fluids; it defines the characteristics required for recognition methods that enable automatic, controlled delivery of welding energy by electrofusion equipment.

Key topics and requirements

• Definitions and classification of automatic recognition systems for electrofusion joints (bar codes, magnetic-card systems, implanted-resistor connectors, self-regulating fittings).
• Requirements for information encoded or provided to electrofusion control units to ensure correct energy delivery for a given fitting.
• Performance and compatibility criteria between fittings and electrofusion equipment to prevent incorrect welding parameters.
• Identification, marking and traceability elements needed for automatic recognition.
• Clarifications and editorial corrections provided by Corrigendum 1 (technical corrections to the 2007 text).

Typical use and users

Used by manufacturers of electrofusion fittings and fusion equipment, quality and conformity assessment bodies, utilities and contractors installing plastic piping systems (gas, water, general fluids), inspection and maintenance teams, and standards committees developing related piping and jointing rules.

FAQ

Q: What is this standard?

A: An international standard that defines the characteristics and requirements for automatic recognition systems used with thermoplastic electrofusion fittings; Corrigendum 1 (2008) provides technical corrections to the 2007 edition.

Q: What does it cover?

A: The standard covers recognition methods (numerical/bar code, magnetic card), electromechanical methods (implanted-resistor connectors) and self-regulating systems, plus the information and compatibility requirements needed so electrofusion equipment can deliver the correct energy for a given fitting.

Q: Who typically uses it?

A: Manufacturers of electrofusion fittings and fusion equipment, utilities (water and gas), installation contractors, inspection bodies and standards developers working on plastic piping systems.

Q: Is it current or superseded?

A: The 2007 edition remains the published edition and was issued with Corrigendum 1 in January 2008 to correct the text. The main ISO record shows the 2007 edition and the 2008 corrigendum as published documents; the 2007 edition has been subject to periodic review. Users should verify current status with ISO or their national standards body before relying on the standard for compliance.

Q: Is it part of a series?

A: It is a standalone ISO international standard developed under ISO/TC 138 (Plastics piping systems), SC4, and sits alongside other ISO deliverables addressing plastic piping materials, fittings and jointing methods; earlier related guidance includes ISO/TR 13950:1997.

Q: What are the key keywords?

A: Electrofusion, automatic recognition, bar code, magnetic card, implanted-resistor connector, self-regulating fitting, plastics piping, jointing, ISO 13950, corrigendum.
