ISO 12570:2000/Amd 1:2013

Overview

ISO 12570:2000/Amd 1:2013 is an important amendment to the international standard focused on the hygrothermal performance of building materials and products. This amendment specifically addresses the determination of moisture content by drying at elevated temperature, refining test parameters to enhance accuracy and reliability. The standard is published by ISO, the International Organization for Standardization, which develops globally recognized technical standards to improve product quality, safety, and efficiency.

This amendment updates the drying temperature range used to measure moisture content in certain building materials, such as cellular plastics, where structural changes may occur during drying. The revision ensures more precise testing aligned with material behavior, which is critical for research, manufacturing, and quality assurance in the building construction sector.

Key Topics

• Hygrothermal Performance: Investigation of materials' behavior relating to moisture and heat transfer, crucial in building envelope design.
• Moisture Content Determination: Essential for assessing material durability, insulation properties, and suitability for various environmental conditions.
• Drying Temperature Adjustment: Amendment changes the drying temperature for certain sensitive materials from 70 ± 2 °C to 65 ± 2 °C to prevent structural alterations during testing.
• Material Sensitivity: Focus on materials like cellular plastics that can experience structural changes within a specific temperature range (65 °C to 105 °C), impacting test results.
• Standardization and Testing Procedures: Prescribes precise test conditions for consistent moisture content measurement across laboratories worldwide.

Applications

• Building Material Testing: Ensures that manufacturers and testing labs can accurately determine moisture levels in products ranging from insulation panels to composites.
• Quality Control: Helps manufacturers maintain consistent moisture specifications, enhancing the performance and longevity of building materials.
• Product Development: Supports R&D in optimizing materials for energy efficiency and resistance to moisture damage.
• Construction Industry: Provides reliable data to architects, engineers, and builders to select appropriate materials for various climate conditions.
• Regulatory Compliance: Facilitates adherence to national and international regulations requiring documented moisture content for specific products.

Related Standards

• ISO 12570 works in conjunction with other complementary standards in the field of thermal performance and moisture measurement, such as:
  • ISO 13788 – Assessment of moisture conditions and surface condensation risk.
  • ISO 10456 – Building materials' thermal insulation properties and design values.
  • ISO 6946 – Building components' thermal resistance and transmittance measurement.
• These standards collectively support robust evaluation of building envelope materials, ensuring energy-efficient and durable construction practices.

By adhering to ISO 12570:2000/Amd 1:2013, professionals in construction and building materials can ensure precise measurement of moisture content through standardized drying procedures, preventing material degradation during testing and improving overall material performance assessments. This supports sustainable building practices and enhances occupant comfort and safety.
