ISO 4650:2026 - Rubber — Identification — Infrared Spectrometric Methods

Rubber — Identification — Infrared Spectrometric Methods

ISO 4650:2026 delivers a state-of-the-art framework for identifying rubber types using both transmission and attenuated total reflectance (ATR) infrared spectroscopic methods. Applicable to a wide array of rubber materials—including raw rubbers, vulcanized or unvulcanized mixes, and thermoplastic elastomers—this qualitative standard is essential for ensuring material authenticity and traceability across the supply chain.

Key technical updates in this edition include revised reference spectra, extended coverage of rubber types (M, O, Q, R, T, U, and TPE groups), and clarified procedures for analyzing blends and pyrolysates. Professionals responsible for material validation—especially in automotive, industrial, and medical device sectors—are directly impacted.

Manufacturers must ensure sample preparation and instrument calibration align with the updated procedures. This not only strengthens quality control but also supports regulatory compliance and fosters supplier confidence.

Key highlights:

• Revised reference spectra for improved accuracy
• Expanded methodology, covering both raw and compounded rubbers
• Enhanced guidance for ATR and pyrolysis-based analyses

EN ISO 844:2026 - Rigid Cellular Plastics: Determination of Compressive Properties (ISO 844:2026)

Rigid Cellular Plastics - Determination of Compressive Properties (ISO 844:2026)

A cornerstone for quality assurance in the plastics industry, EN ISO 844:2026 (aligned with ISO 844:2026) outlines precise methods for measuring compressive strength, strain, stress at 10% strain, and compressive modulus in rigid cellular plastics. The standard introduces two distinct test procedures:

• Procedure A: Uses compression plate displacement to measure nominal properties.
• Procedure B: Utilizes extensometers for conventional property determination.

This edition brings critical terminology clarity (e.g., compressive strain), new details for conditioning and required apparatus, and revised criteria for reporting force-drop and specimen preparation. Implementing these protocols ensures accurate, repeatable testing for applications ranging from insulation foams to engineering panels.

Compliance is required for manufacturers, quality teams, researchers, and testing laboratories producing or relying on cellular plastic components. Adherence to EN ISO 844:2026 safeguards product consistency, supports third-party certifications, and streamlines routes to market.

Key highlights:

• Dual procedure options for robust compressive evaluation
• Updated terms and definitions for industry clarity
• Forced withdrawal of conflicting national standards by January 2027

ISO 9782:2026 - Plastics — Reinforced Moulding Compounds and Prepregs — Determination of Apparent Volatile-Matter Content

Plastics — Reinforced Moulding Compounds and Prepregs — Determination of Apparent Volatile-Matter Content

The revised ISO 9782:2026 standard specifies methodology for determining the apparent volatile-matter content in pre-impregnated yarns, tapes, sheets (SMC), and fabrics—covering both unidirectional and multidirectional fibre-reinforced prepregs with thermosetting resin matrices.

This edition introduces greater accuracy requirements (balance to ±0.1 mg), mandates a minimum of three test specimens, and provides clear procedural instructions—such as optimal specimen placement for heat exposure—to yield consistent, actionable results. The standard is crucial for composite manufacturers, material suppliers, and technical auditors concerned with controlling the quality and performance of advanced moulding compounds.

Proper determination of volatile content ensures suitable processability, storage stability, and superior end-use performance, particularly in aerospace, automotive, marine, and industrial composites.

Key highlights:

• Enhanced weighing precision for improved result reliability
• Detailed specimen handling and conditioning guidelines
• Tailored for all thermosetting resin types (excluding unimpregnated fibers)

ISO 22785-6:2026 - Paints and Varnishes — Coatings on Plastics and Composites — Part 6: Stone-Chip Resistance Testing

Paints and Varnishes — Coatings on Plastics and Composites — Part 6: Stone-Chip Resistance Testing

With the increasing use of plastic and composite substrates in automotive, transportation, and consumer goods, ISO 22785-6:2026 brings targeted test procedures for evaluating the stone-chip resistance of coatings applied to these materials. The standard comprehensively addresses both the substrate influence and the impact modes—offering stationary multi-impact tests, single-impact (guided), and single-impact (free-flying) protocols.

This first edition enables users to replicate real-world damage scenarios (such as road chippings or debris impact) and evaluate coating durability, adhesion, and protective quality. Laboratories, coating developers, OEMs, and Tier-1 suppliers must implement these methods to ensure their coatings maintain functional and aesthetic properties under harsh service conditions.

Key highlights:

• Newly developed multi-impact and single-impact test options
• Detailed substrate preparation and conditioning guidance
• Critical for automotive, transport, and high-performance plastics sectors
