Full title and description

STB DIN EN 12320 E 2020-10 — Building hardware — Padlocks and padlock fittings — Requirements and test methods. This designation refers to the German/European draft publication (E DIN EN 12320:2020‑10 / prEN 12320:2020) presenting requirements, classifications and test procedures for mechanical padlocks and padlock fittings, in bilingual (German/English) form.

Abstract

EN 12320 specifies performance requirements and test methods for padlocks and padlock fittings used in buildings and for general use. It covers mechanical performance (strength, function, durability), security grading by simulated-attack tests, and corrosion resistance (with cross-reference to corrosion test methods). The 2020-10 “E” version is a draft/national publication that was issued in 2020 and later superseded by the formal DIN EN publication in 2022.

General information

• Status: Draft national publication (E DIN EN 12320:2020-10) — issued in 2020 and later withdrawn/superseded by the subsequent DIN EN edition (see replacement note).
• Publication date: Issued 2020-10 (date of this E DIN EN draft entry: 01 October 2020; AENOR notes date of issue as 2020-09-04).
• Publisher: DIN (German adoption of the CEN/EN document) — this file is a German/English (DIN EN) release of the European standard.
• ICS / categories: 91.190 (Building accessories / building hardware).
• Edition / version: E DIN EN 12320:2020-10 (draft / prEN 12320:2020 designation).
• Number of pages: 63 pages (as listed for the 2020-10 electronic/print release); later final national adoption editions list different page counts.

Scope

This document applies to mechanical padlocks and padlock fittings intended for building and general use. It specifies test methods and performance requirements addressing strength, security (graded by simulated attack), function, durability and corrosion resistance (the latter often referenced to EN/ISO corrosion standards). Excluded items are cables and chains; detailed sampling, classification and marking requirements are included in the standard text.

Key topics and requirements

• Classification of security into six grades based on performance (attack) tests.
• Performance requirements and test methods for strength, durability and operational function.
• Corrosion-resistance categories (with cross-reference to relevant corrosion test standards).
• Marking and information to be supplied (identification, grade, manufacturer).
• Sampling, test rig arrangements and sequence of tests for type approval and production checks.
• Requirements for padlock fittings and form-on-supply (dimensions, materials, constructional details).

Typical use and users

Primary users are padlock and building-hardware manufacturers, test and certification laboratories, specifiers and purchasers of security hardware, architects and building product compliance engineers, and procurement teams for buildings and infrastructure. The standard is used for product development, type testing, third‑party certification and contract specification.

Related standards

Standards commonly referenced together with EN 12320 include EN 1303 (cylinders for locks — requirements and test methods), EN 1670 (corrosion resistance of building hardware) and other EN standards for locks and hardware performance and testing; earlier and later editions of EN 12320 (2001, 2012, 2021/2022 national adoptions) provide historical context and may be referenced for legacy products.

FAQ

Q: What is this standard?

A: EN 12320 is a European standard that sets requirements and test methods for mechanical padlocks and padlock fittings used in buildings and general applications. The designation shown (STB DIN EN 12320 E 2020-10) refers to the German/European draft release published in October 2020.

Q: What does it cover?

A: It covers classification, performance requirements and the test procedures needed to assess strength, security (attack resistance), function, durability and corrosion resistance of padlocks and their fittings. It specifies marking and sampling rules for type testing and production control.

Q: Who typically uses it?

A: Manufacturers of padlocks and hardware, testing and certification bodies, specifiers, architects, procurement departments and compliance engineers use the standard to design, test, verify and specify padlock performance.

Q: Is it current or superseded?

A: The E DIN EN 12320:2020-10 entry is a draft/national publication issued in 2020 and later withdrawn/superseded by the subsequent national adoption of the final EN edition (listed as DIN EN 12320:2022-03 / EN 12320:2021 in national catalogs). Users should consult the final adopted edition (DIN EN 12320:2022 / EN 12320:2021) for the current normative text.

Q: Is it part of a series?

A: EN 12320 is part of the building‑hardware family of EN standards; it is linked to other lock and hardware standards (for example EN 1303 for cylinders and EN 1670 for corrosion testing) and exists in multiple editions (2001, 2012, draft 2020, and the later 2021/2022 adoption).

Q: What are the key keywords?

A: Padlocks, padlock fittings, security grade, durability, corrosion resistance, test methods, classification, marking, DIN EN 12320, building hardware.
