Full title and description

STB DIN 32508:2000-12 — Micro devices for brazing and welding with own hydrogen and oxygen production: mechanical and gas-engineering requirements, testing and marking. This record corresponds to the DIN original titled "Mikro-Löt- und -Schweißgeräte mit eigener Wasserstoff-/Sauerstoff-Erzeugung – Mechanische und gastechnische Anforderungen, Prüfung, Kennzeichnung."

Abstract

This standard specifies basic mechanical, gas-technology and safety related requirements, test methods and marking/identification rules for small oxy‑hydrogen (H2/O2) micro‑brazing and micro‑welding devices that generate their own hydrogen and oxygen on demand. It covers construction and gas-handling aspects relevant to safe and reliable operation of such units.

General information

• Status: Current (DIN entry shows the 2000 edition as the established document and notes replacement of an earlier 1993 edition).
• Publication date: 2000-12 (December 2000).
• Publisher: Deutsches Institut für Normung (DIN).
• ICS / categories: 25.160 — Welding, brazing and soldering (including subcategories for welding equipment and brazing/soldering).
• Edition / version: DIN 32508:2000-12 (this edition, replacing DIN 32508:1993-04).
• Number of pages: 6 pages.

Scope

The standard applies to compact micro‑brazing and micro‑welding devices that produce oxyhydrogen gas by electrolysis of water (on‑demand H2/O2 generation) and are intended for precision joining tasks. It defines required mechanical construction features, gas‑engineering safety and sealing measures, functional tests and marking/identification to ensure safe operation and traceability. It does not replace broader electrical safety or electromagnetic compatibility standards that may also apply to powered equipment.

Key topics and requirements

• Mechanical construction and robustness requirements for micro‑torch units and housings.
• Gas‑engineering requirements for on‑site H2/O2 production, hoses, valves and flow control to prevent unsafe gas accumulation.
• Performance and type/acceptance tests to verify safe generation, delivery and combustion of the oxyhydrogen flame.
• Marking, labelling and identification requirements to provide manufacturer, model and safety information.
• Basic safety and user‑information provisions (warnings, instructions for use, maintenance recommendations).

Typical use and users

Typical users include manufacturers of micro‑welding/brazing equipment, workshop technicians, jewelers, electronics and precision‑component assemblers, repair specialists, quality and compliance engineers, and testing/inspection bodies responsible for equipment acceptance and maintenance.

Related standards
