Full title and description
DIN EN 45501:2016-03 — Metrological aspects of non-automatic weighing instruments; German version of EN 45501:2015. This document specifies metrological and technical requirements, tests, type-approval and verification procedures for non-automatic weighing instruments (NAWIs) used for commercial and regulatory purposes.
Abstract
EN 45501:2015 (adopted in German as DIN EN 45501:2016-03) is the European standard adapted from OIML Recommendation R76‑1 (2006). It defines classification, metrological requirements (units, scale intervals, maximum permissible errors), performance under influence factors (temperature, vibration, electromagnetic disturbances), and the tests required for type approval and initial/periodic verification of NAWIs. The standard supports conformity with EU legal‑metrology directives.
General information
- Status: Current (German adoption of EN 45501:2015).
- Publication date: 2016-03 (DIN publication 1 March 2016; original EN version 2015).
- Publisher: Deutsches Institut für Normung (DIN) — German version of the CEN/CENELEC EN standard.
- ICS / categories: 17.100 (Measurement of force, weight and pressure); commonly also referenced with 17.060 (measurement of mass, density, etc.).
- Edition / version: German version of EN 45501:2015 (Edition 1 of EN 45501:2015).
- Number of pages: 164 pages (DIN published German text).
Scope
The standard applies to non-automatic weighing instruments (NAWIs) that require an operator during the weighing process to decide that the weighing result is acceptable. It covers single-range, multi-interval and certain special-purpose instruments, defining metrological characteristics, influence quantities, required performance, and the tests for type evaluation, pattern approval and verification to meet legal‑metrology requirements in the EU. The text is an adaptation of OIML R76‑1 (2006) and intended to align with EU directives on NAWIs.
Key topics and requirements
- Definitions and classification of NAWIs (single-range, multi-interval, multiple‑range, special-purpose instruments).
- Metrological characteristics: maximum capacity, minimum capacity, scale interval (d), discrimination, resolution and repeatability requirements.
- Maximum permissible errors (MPE) and performance criteria under influence quantities (temperature, vibration, overload, electromagnetic disturbances).
- Type approval / type evaluation tests: administrative, constructional and metrological tests, endurance and influence tests, software/module evaluation where applicable.
- Initial and subsequent verification procedures, marking and documentation required for legal use.
Typical use and users
Manufacturers and designers of weighing instruments, conformity assessment bodies, notified bodies and national metrology/verification authorities use this standard for product design, type approval, and legal verification. Calibration and testing laboratories, system integrators, and large end users (commerce, industry, retail, transport) rely on the requirements for procurement and quality assurance of legally controlled weighing equipment.
Related standards
EN 45501:2015 is based on OIML R76‑1 (2006) (OIML recommendation for NAWIs) and supersedes older EN 45501:1992. It is related to EU legislation for NAWIs (for example Directive 2009/23/EC and the measuring instruments directive framework) and to other EN/OIML documents addressing modules, software, and specific instrument types.

FAQ
Q: What is this standard?
A: DIN EN 45501:2016-03 is the German adoption of EN 45501:2015, titled "Metrological aspects of non-automatic weighing instruments". It sets metrological and technical requirements and test procedures for NAWIs.
Q: What does it cover?
A: It covers classification of NAWIs, metrological characteristics (capacity, scale interval, resolution), maximum permissible errors, influence factor tests (temperature, vibration, EMC), and procedures for type evaluation, initial verification and marking/documentation for legal use.
Q: Who typically uses it?
A: Instrument manufacturers, conformity assessment and notified bodies, national metrology/verification authorities, calibration laboratories, and procurement/quality teams in industries and commerce that require legally compliant weighing equipment.
Q: Is it current or superseded?
A: EN 45501:2015 is the current European edition; the German adoption (DIN EN 45501:2016-03) is current and replaced the earlier EN 45501:1992. Users should always check national registers or the publisher for any corrigenda/amendments or later revisions.
Q: Is it part of a series?
A: Yes — EN 45501 is the primary European standard for NAWIs and is linked to OIML R76‑1 (the corresponding OIML recommendation). There are related national/adopted versions and additional EN/OIML documents covering modules, software and specific instrument classes.
Q: What are the key keywords?
A: NAWI, non-automatic weighing instrument, weighing scale, balance, MPE, verification, type approval, legal metrology, OIML R76.
