BS ISO 29472-2008 + A1-2014 PDF

Full title and description

STB BS ISO 29472:2008 + A1:2014 — Thermal insulating products for building applications — Determination of dimensional stability under specified temperature and humidity conditions. This publication is the British adoption of ISO 29472:2008 together with Amendment 1 (2014), and specifies apparatus, specimen preparation and procedures to evaluate dimensional changes of thermal insulating products when exposed to defined temperature and relative-humidity conditions.

Abstract

ISO 29472:2008 defines test methods to measure dimensional stability of thermal insulating products under specified temperature and humidity exposures. Amendment A1:2014 provides clarifications and technical corrections to the original 2008 text. The combined BS adoption republishes the ISO text for use in the UK market, preserving the international test method and adding national identification.

Scope

This standard specifies the equipment, specimen preparation and test procedures for evaluating dimensional changes (linear and planar) of thermal insulating products when exposed to defined temperature and relative-humidity conditions and durations. It offers a range of test conditions from which appropriate procedures may be selected for product evaluation and comparison; it is applicable to thermal insulating products used in building applications.

Key topics and requirements

• Definition of test specimens and conditioning prior to exposure.
• Specified test atmospheres (temperature and relative humidity) and exposure durations for dimensional stability measurements.
• Apparatus and measuring equipment requirements for accurate length/area change determination.
• Procedures for reporting results and selecting relevant test conditions for specific products.
• Reference to normative values and the role of the amendment in clarifying measurement/tolerance details.

Typical use and users

Used by manufacturers of thermal insulation, testing and calibration laboratories, product conformity assessors, specification writers and building product researchers. The standard is applied when assessing dimensional stability for product development, quality control, third‑party testing and when specifying performance requirements in procurement and construction documentation.

Related standards

Commonly referenced standards in the thermal insulation family include other ISO test methods for mechanical, dimensional and moisture-related properties of insulating products (for example ISO standards addressing tensile strength, dimensional measurement and behaviour under load). National adoptions and related EN/ISO documents address complementary tests such as compressive deformation, thermal expansion and water vapour transmission.

FAQ

Q: What is this standard?

A: It is the international test method ISO 29472:2008 (with Amendment 1:2014) for determining dimensional stability of thermal insulating products under specified temperature and humidity conditions; published in the UK as BS ISO 29472:2008+A1:2014.

Q: What does it cover?

A: It covers specimen preparation, required apparatus, specified exposure atmospheres (temperature and relative humidity), measurement procedures for dimensional change and reporting conventions so that products can be compared and assessed for dimensional stability.

Q: Who typically uses it?

A: Insulation manufacturers, independent testing laboratories, product certifiers, specifiers and researchers use the standard for product development, conformity assessment and quality control.

Q: Is it current or superseded?

A: The original ISO 29472:2008 remains the base standard and was issued with Amendment 1 in 2014; the BS adoption (BS ISO 29472:2008+A1:2014) was published subsequently. Users should check for any later revisions or withdrawals at the issuing body; as of the amendment publication the standard was published/confirmed in force.

Q: Is it part of a series?

A: Yes — it belongs to the family of ISO test methods for thermal insulating products (ISO/TC 163/SC 1) where complementary documents address other mechanical, thermal and moisture‑related test methods for insulating materials.

Q: What are the key keywords?

A: Dimensional stability, thermal insulation, temperature and humidity conditioning, test method, specimen, ISO 29472, A1:2014, BS adoption.
