DIN EN ISO 29767 2019-11 PDF

Full title and description

DIN EN ISO 29767:2019-11 — Thermal insulating products for building applications — Determination of short-term water absorption by partial immersion. This is the German (EN) adoption of ISO 29767:2019 and specifies the test arrangement and procedures to determine short-term water uptake of thermal insulation specimens by partial immersion (intended to simulate a 24 h rain exposure during construction).

Abstract

The standard defines equipment, specimen preparation, test conditions and calculation procedures for measuring short‑term water absorption of thermal insulating products by partial immersion. Results are reported as mass increase per unit area (or alternative format where applicable), and the procedure is intended to reproduce water uptake caused by a 24‑hour rain period on exposed products during erection or construction.

Scope

This standard applies to thermal insulating products for building applications and specifies the apparatus and procedures for determining short-term water absorption by partial immersion. It is intended for products that may be exposed to rain or wetting during handling, transport or construction and simulates the water uptake expected from a 24‑hour rain event. It does not cover long‑term water absorption or all product types where different test methods may be more appropriate.

Key topics and requirements

• Definition of test apparatus and fixtures for partial immersion.
• Specimen selection, conditioning and preparation (dimensions, cutting and surface condition).
• Test procedure for partial immersion, immersion depth and test duration representative of short‑term exposure (24 h simulation).
• Calculation and expression of results (mass increase, normalized to specimen area or other specified basis).
• Requirements for environmental and laboratory conditions during testing (temperature, humidity).
• Normative references and reporting requirements for reproducibility and traceability.
• Notes on applicability limits and interpretation of results for different insulation materials.

Typical use and users

Used by manufacturers of thermal insulation, independent testing laboratories, certification and conformity-assessment bodies, product developers and material researchers to evaluate short-term water uptake performance. Architects, specifiers and building envelope engineers may reference the test results when selecting insulation products for applications where temporary wetting during construction is a concern.

Related standards

Replaces and updates earlier national/EN tests (for example DIN EN 1609:2013 was replaced by the EN ISO adoption). The document is produced in cooperation between CEN/TC 88 and ISO/TC 163/SC 1; related ISO and EN standards on thermal insulation test methods and long‑term water absorption should be consulted for comprehensive assessment.

FAQ

Q: What is this standard?

A: DIN EN ISO 29767:2019-11 is the German national adoption of ISO 29767:2019 — a standardized test method for determining short‑term water absorption of thermal insulating products by partial immersion.

Q: What does it cover?

A: It covers apparatus, specimen preparation and a defined partial‑immersion test procedure (intended to simulate a 24‑hour rain period) and gives instructions for calculating and reporting the resulting water uptake. It is focused on short‑term exposure rather than long‑term saturation.

Q: Who typically uses it?

A: Insulation manufacturers, independent test laboratories, certification bodies, product developers, and building professionals (architects, specifiers and engineers) who need to assess a product’s susceptibility to short‑term wetting during construction or handling.

Q: Is it current or superseded?

A: The 2019 edition (ISO 29767:2019 / EN ISO 29767:2019) is the current edition that replaces the 2008 edition (ISO 29767:2008). National adoption as DIN EN ISO 29767 was published in November 2019. Standards are subject to periodic review (typically every five years) so users should check national catalogues for any subsequent revisions.

Q: Is it part of a series?

A: It is part of the body of ISO/CEN test methods for thermal insulating products and complements other ISO/EN standards that address different performance characteristics (thermal resistance, long‑term water absorption, fire behaviour, dimensional stability, etc.). It replaces earlier national EN methods for short‑term water absorption.

Q: What are the key keywords?

A: Short‑term water absorption, partial immersion, thermal insulation, test method, 24‑hour rain simulation, EN ISO, DIN, specimen preparation.
