Full title and description

STB BS EN 1707-1997 — Conical fittings with a 6 % (Luer) taper for syringes, needles and certain other medical equipment — Part 2: Lock fittings. This document is the British (BS) adoption of the European Standard EN 1707:1996 (which corresponds to ISO 594‑2) and specifies dimensional, performance and test requirements for lock (Luer‑lock) fittings used with syringes, needles and related medical devices.

Abstract

This standard defines the geometry, tolerances, gauging, performance requirements and test methods for conical lock fittings having a 6 % (Luer) taper intended for use with hypodermic syringes, needles and certain other medical equipment. It establishes requirements to ensure interchangeability, secure connections (locking), and limits on liquid leakage and mechanical performance under expected usage conditions.

General information

• Status: Withdrawn / superseded in practice by the modern small‑bore connector series (see related standards below).
• Publication date: BS adoption 1997 (original EN text: 1996).
• Publisher: British Standards Institution (BSI) — adoption of CEN/EN 1707 (CEN/TC 205).
• ICS / categories: 11.040.25 — Syringes, needles and catheters / medical injection equipment.
• Edition / version: BS EN 1707:1997 (equivalent to EN 1707:1996 / corresponding to ISO 594‑2).
• Number of pages: Typical published edition length ~11 pages (ISO/EN part reference documents show similar pagination).

Scope

The standard applies to conical lock fittings with a 6% (Luer) taper intended for medical use with hypodermic syringes, needles and certain other apparatus (for example transfusion equipment). It covers dimensions and tolerances, gauging procedures, functional performance (locking engagement and retention), and tests for leakage and mechanical integrity. Elastomeric or highly flexible connector materials are generally excluded from the core gauging provisions; the document is focused on rigid and semi‑rigid fittings.

Key topics and requirements

• Dimensional specifications and tolerances for male and female Luer lock fittings (6 % taper geometry) to ensure interchangeability.
• Gauging and reference‑fitting procedures for verifying conformance to dimensional limits.
• Liquid leakage tests and acceptance criteria for assembled fittings under specified pressures/conditions.
• Mechanical performance tests (engagement/retention force, resistance to axial and torsional loads, cyclic connection/disconnection durability).
• Materials and marking recommendations where relevant for traceability and safety.
• Normative references to related ISO/CEN test methods and medical‑device safety standards used to evaluate biological/chemical compatibility and packaging/sterilization interactions.

Typical use and users

Primary users include medical device manufacturers (syringes, needles, infusion sets), component suppliers (fittings and connector manufacturers), quality and regulatory teams verifying connector interchangeability, test laboratories performing dimensional and leakage testing, and procurement/specification engineers responsible for ensuring compatibility of devices used in healthcare settings.

Related standards

Key related documents and successor standards include ISO 594‑1 (general requirements for Luer taper connectors) and ISO 594‑2 (lock fittings) — EN 1707 corresponds to ISO 594‑2; EN 20594‑1 / EN ISO equivalents cover Part 1 aspects. The ISO/CEN small‑bore connector series (ISO/EN ISO 80369‑7) was developed to replace legacy Luer standards for certain applications and is the modern replacement addressing misconnection risks; EN ISO 80369‑7 (published 2016/2017) supersedes older EN/ISO Luer lock documents for many uses.

FAQ

Q: What is this standard?

A: It is the British adoption (BS EN 1707:1997) of the European Standard EN 1707:1996, which specifies requirements and test methods for Luer‑type conical lock fittings (6% taper) used with syringes, needles and certain medical equipment.

Q: What does it cover?

A: Dimensions and tolerances for male and female Luer lock fittings, gauging procedures, performance and leakage tests, and related acceptance criteria to ensure secure and interchangeable connections in medical devices.

Q: Who typically uses it?

A: Medical device manufacturers, connector/fitting suppliers, test laboratories, quality/regulatory professionals, and procurement/specification engineers concerned with connector compatibility and safety in healthcare products.

Q: Is it current or superseded?

A: The BS EN 1707:1997/EN 1707:1996 provisions for Luer lock fittings have been superseded in practice by the newer small‑bore connector standards (ISO/EN ISO 80369‑7 series) which were published in 2016/2017 to address misconnection and safety issues and replace the legacy ISO 594 / EN 1707 family for many applications. Users should refer to EN ISO 80369‑7 for current requirements where applicable.

Q: Is it part of a series?

A: Yes — it is part of the Luer connector family (ISO 594 series: Part 1 general requirements and Part 2 lock fittings). The modern equivalent work is now in the ISO 80369 series (small‑bore connectors) which consolidates and replaces older Luer standards for specified healthcare applications.

Q: What are the key keywords?

A: Luer, Luer lock, 6% taper, conical fittings, lock fittings, syringe connectors, leakage test, gauging, ISO 594, EN 1707, BS EN 1707.
