Detailed Standards Coverage

ISO 844:2026 – Testing Rigid Cellular Plastics for Compressive Properties

Rigid cellular plastics — Determination of compressive properties

This eighth edition of ISO 844 specifies comprehensive methodologies for determining the compressive strength, strain, stress at 10% nominal compressive strain, and compressive modulus in rigid cellular plastics. Two clearly differentiated procedures are outlined:

• Procedure A: Uses compression plate displacement for nominal property determination, suitable for general quality assurance.
• Procedure B: Relies on extensometer readings to capture actual specimen deformation, yielding conventional property values.

The standard addresses testing apparatus, specimen requirements, and precision guidelines, enabling manufacturers and testers to produce accurate and reproducible data. Notable updates in 2026 include refined terminology, clarification of “nominal” versus “conventional” values, and modified test principles for increased industry alignment.

Who Should Comply: Manufacturers of rigid cellular plastics, QA labs, research institutions, and procurement specialists requiring validated product data for construction, insulation, or packaging applications.

Implementation Implications:

• Ensures consistent measurement for product comparison and certification
• Supports regulatory submissions and client specifications
• Harmonizes updated terminology (e.g., “force-drop” replaces older “necking” term)

Key highlights:

• Dual procedures for broad applicability (A: nominal, B: conventional)
• Updated strain definitions and calculation methods
• Enhanced reproducibility and clarity in reporting

ISO/TR 19032:2026 – Polyethylene Reference Film for Weathering Assessment

Plastics — Use of polyethylene reference film (PERF) for monitoring laboratory and outdoor weathering conditions

This technical report details the use of polyethylene reference film (PERF) as a benchmark material for monitoring and comparing the environmental ageing (weathering) of plastics, whether tested in laboratory simulation or real outdoor conditions. Perf serves as a standardized material whose degradation under UV and thermal exposure is well characterized and can be quantitatively tracked via changes in the carbonyl index using FTIR (Fourier Transform Infrared) spectroscopy.

The document covers:

• Preparation and properties of reference materials
• Standardized FTIR protocols for measuring carbonyl group formation
• Implementation guidance for artificial (e.g., xenon-arc, UV lamp) and natural exposure tests

Who Should Comply: Material developers, QA/test laboratories, and manufacturers seeking to validate the weathering performance of plastic products, coatings, or ingredients.

Implementation Implications:

• Allows direct comparison of accelerated and natural weathering results
• Facilitates benchmarking across laboratories and between material batches
• Supports claims of material durability and compliance to performance requirements

Key highlights:

• Defines PERF material characteristics for consistent results
• Detailed procedure for measuring photo-oxidation (carbonyl index)
• Harmonizes laboratory and field weathering monitoring

ISO 24829:2026 – Aldehydes and Ketones Content in Polyether and Polymer Polyols

Plastics — Polyether polyols and polymer polyols — Determination of aldehydes and ketones

As the polyurethane supply chain grows in response to automotive and consumer demands, ISO 24829 addresses increasing calls for analytical rigor in measuring volatile organic compounds (VOCs) in raw materials. This standard specifies precise high-performance liquid chromatography (HPLC) methods for quantifying formaldehyde, acetaldehyde, acrolein, and acetone in polyether and polymer polyols.

This standard is vital for industries where emissions control and material purity are tightly regulated, such as automotive interiors, furniture, adhesives, and molded foams.

Who Should Comply: Polyol manufacturers, polyurethane producers, automotive suppliers (OEMs), and labs certifying raw materials for low emissions and quality assurance.

Implementation Implications:

• Provides reproducible, sensitive VOC measurement protocols
• Enables manufacturers to meet strict OEM and regulatory requirements
• Supports industry efforts toward sustainability and consumer safety

Key highlights:

• Specifies calibration, sample preparation, and HPLC analysis
• Covers all major industry-relevant aldehydes and ketones
• Includes quality criteria for method precision and reporting
