• Comprehensive instructions for visualizing PSDs across all particle size ranges, regardless of the analysis method employed (e.g., sieving, light scattering, image analysis).
• Guidance for representing both normalized and non-normalized distributions, as well as two-dimensional distribution mapping (size and shape).

This latest revision significantly enhances the scope of the previous edition with expanded definitions, new mathematical formulae, additional graphical representations (including for multidimensional and separated particle systems), and more robust annexed examples.

Industries affected: Chemical processing, pharmaceuticals, environmental monitoring, materials science, food technology, mining, and any domain dealing with powders, emulsions, or aerosols.

Regulatory landscape: This document often underpins contractual delivery, inter-laboratory data reporting, and regulatory submission formats internationally.

Key highlights:

• Universal, method-neutral guidance and terminology for PSD visualization
• Extended methods for logarithmic and two-dimensional graphical representation
• Direct support for digital data management and cross-platform results comparison

EN IEC 60068-2-30:2025 - Environmental Testing—Cyclic Damp Heat

Environmental testing - Part 2-30: Tests - Test Db: Damp heat, cyclic (12 h + 12 h cycle)

EN IEC 60068-2-30:2025 addresses the suitability of components, assemblies, and packaging for use, transport, and storage under conditions of periodically cycling temperature and high humidity—conditions known to challenge the reliability of sensitive materials and electronics through phenomena such as condensation and corrosion.

• Refined requirements for test chamber design, operation, and monitoring
• New temperature tolerance limits reflecting current climatic reliability demands
• Updated figures, conditioning limits, and measurement procedures for improved clarity
• Expanded and clarified requirements for intermediate test measurements and reporting
• Guidance for variant test cycles, both for energized and non-energized specimens

Its adoption is central for sectors where field reliability and accelerated aging assessments are critical, including automotive, aerospace, defense, telecommunications, and consumer electronics manufacturing.

Implementation context: EN IEC 60068-2-30 is widely referenced in supply chain quality contracts and regulatory acceptance of component durability under challenging climatic conditions.
