Overview

EN ISO 29770:2022 is a European standard developed by CEN in alignment with ISO 29770:2022 that specifies the equipment, methods, and procedures for the accurate determination of the thickness of thermal insulating products used in floating-floor applications. These products primarily serve to provide impact sound insulation in building constructions. The standard replaces the previous EN 12431:2013 and introduces precise testing conditions, apparatus requirements, and specimen preparation guidelines to ensure consistent, reliable measurement of insulation product thickness.

Key Topics

• Scope and Purpose
  EN ISO 29770:2022 focuses on thermal insulating products designed for floating floors to reduce impact sound transmission. It details controlled procedures for measuring product thickness under specific load conditions, critical for ensuring product performance and compliance.

• Test Equipment and Apparatus
  The standard specifies the usage of:

  • Dial gauges with 0.1 mm accuracy, mounted on rigid frames
  • Rigid, flat base and pressure plates matching or exceeding specimen size
  • Pressure devices capable of exerting pressures of 0.25 kPa, 2 kPa, and 50 kPa
  • Alternatively, a compression-testing machine with force and displacement sensors meeting equivalent accuracy can be used

• Specimen Preparation and Conditioning

  • Test specimens must be square cut, typically 200 mm sides, without edges or structural alteration
  • Conditioning prior to testing requires storage at 23 ± 5 °C, or 23 ± 2 °C with 50 ± 5% relative humidity for accuracy, with adjustments for tropical climates as needed
  • Number of specimens depends on product standards or, lacking these, a minimum of 10 specimens is recommended

• Measurement Procedure

  • Thickness is measured as the distance between the base plate and the pressure plate under specified loads
  • The standard describes measuring thickness under a 250 Pa load (dL), which corresponds to operational pressures in typical floating-floor applications
  • Detailed diagrams illustrate pressure vs time curves to guide consistent measurement and interpretation

• Reporting and Accuracy

  • Test reports must document conditions, specimen details, equipment used, and measured thickness values
  • The standard emphasizes measurement accuracy with clear tolerances on instrument resolution and pressure application
  • Ensures repeatability and comparability across laboratories and manufacturers

Applications

EN ISO 29770:2022 is crucial for manufacturers, testing laboratories, and quality control professionals involved in:

• Building and Construction Industry

  • Ensuring thermal insulation products meet thickness specifications essential for acoustic performance in floating floors
  • Verifying product compliance prior to market entry or installation in residential, commercial, and industrial buildings

• Product Development and Certification

  • Designing new insulating materials with accurate thickness characterization under operational loads
  • Supporting certification and labelling requirements that depend on verified thickness metrics

• Quality Assurance and Standardization

  • Enabling manufacturers to maintain production quality and consistency
  • Providing a standardized benchmark for thickness measurement used across Europe and internationally

Related Standards

This standard references and complements several other key documents related to thermal insulation and testing:

• ISO 29768: Determination of linear dimensions of test specimens for thermal insulating products
• EN 12431:2013: Superseded by EN ISO 29770:2022, previously covering similar thickness determination methods
• Other thermal and acoustic insulation testing standards under ISO/TC 163 and CEN/TC 88 cover additional performance metrics such as thermal conductivity and sound insulation

Using EN ISO 29770:2022 alongside these standards ensures comprehensive evaluation of insulating products for floating-floor applications, supporting regulatory compliance and enhancing building performance.
