Full title and description

STB UNE-EN 442-2:2015 — Radiators and convectors — Part 2: Test methods and rating. This is the Spanish national adoption (UNE-EN) of the European standard (EN 442‑2) that specifies laboratory test procedures and rating methods for permanently installed radiators and convectors fed with water or steam (temperatures below 120 °C).

Abstract

EN 442-2 defines the test arrangement, measurement procedures, admissible tolerances and sampling criteria used to determine the rated (standard) thermal output and other performance characteristics of radiators and convectors intended for permanent installation in buildings. The part excludes fan‑assisted appliances, trench convectors and independent (self‑contained) heating appliances and requires manufacturers to provide unified product data so correct application is ensured.

General information

• Status: Active / Adopted as UNE-EN (confirmed edition retained in national catalogues).
• Publication date: 4 November 2015 (UNE adoption; EN technical text published as EN 442‑2:2014/2015 in national catalogs).
• Publisher: AENOR (Asociación Española de Normalización y Certificación) — national publication as UNE-EN 442-2:2015.
• ICS / categories: 91.140.10 — Central heating systems / Heat emitters.
• Edition / version: UNE-EN 442-2:2015 (identical/adopted from EN 442‑2 technical text).
• Number of pages: Approximately 80–83 pages (commonly listed as c. 80–82 pages in national catalogues).

Scope

This part of EN 442 specifies the laboratory arrangements and the methods of test to be used to determine the standard thermal output and other characteristics (e.g. characteristic curve, rated output at specified ΔT values) of metal radiators and convectors permanently installed in building works and supplied from a remote heat source with water or steam at temperatures below 120 °C. It sets admissible tolerances, criteria for sample selection and provisions for verifying ongoing production conformity. Fan‑assisted units, trench convectors and self‑contained appliances are excluded.

Key topics and requirements

• Definition of test rig and laboratory arrangements for thermal output measurement.
• Determination of rated thermal output (standard output) at reference ΔT (e.g. 30 K and 50 K) and provision of characteristic curve parameters (coefficient K and exponent n).
• Admissible tolerances on measured values and dimensional/production tolerances for conformity assessment.
• Sampling rules and criteria for type testing and for demonstrating conformity of ongoing production.
• Requirements for test reports and manufacturer information to be supplied with the product (catalogue data, characteristic curves, operating conditions).
• Specific exclusions and applicability limits (fan‑assisted and trench units, independent heaters).

Typical use and users

Primary users are radiator and convector manufacturers, independent testing laboratories, conformity assessment bodies, HVAC design engineers, product certifiers and procurement/specification teams. The standard is used to produce rated output data for product datasheets, to support declarations of performance (DoP) and CE marking where applicable, and to verify production conformity during factory surveillance or type testing.

Related standards

EN 442 is a multi‑part series. The principal related documents are EN 442‑1 (Part 1: Technical specifications and requirements) and earlier parts that were superseded; national adoptions (UNE‑EN 442‑1:2015 / UNE‑EN 442‑2:2015) provide the paired specification and test method texts used together. Other complementary standards and regulations relevant to product safety, materials and construction products regulation are referenced in the normative text.

FAQ

Q: What is this standard?

A: STB UNE-EN 442-2:2015 is the national adoption (UNE‑EN) of the European standard EN 442‑2 defining test methods and rating procedures for radiators and convectors installed in building heating systems.

Q: What does it cover?

A: It covers laboratory arrangements, measurement procedures, tolerances, sampling and reporting rules used to determine rated thermal output and related performance information for radiators and convectors (water/steam below 120 °C). It excludes fan‑assisted units, trench convectors and self‑contained heaters.

Q: Who typically uses it?

A: Manufacturers, test laboratories, HVAC designers, certifiers and procurement/specification professionals use the standard to generate and verify declared thermal output data and to support conformity procedures.

Q: Is it current or superseded?

A: The UNE adoption shown is UNE‑EN 442‑2:2015 (publication/adoption in 2015) and national catalogues list the edition as active; some national listings note confirmation dates (for example confirmation in 2020). Users should check the national standards body catalog for the most recent confirmation or revision status before compliance work.

Q: Is it part of a series?

A: Yes — EN 442 is a multi‑part European standard. Part 1 covers technical specifications and requirements; Part 2 covers test methods and rating. Earlier EN/ national parts were consolidated and updated in the EN 442 series revisions.
