HD 478.2.5 S1:1993 - Overview

Standard reference: HD 478.2.5 S1:1993 (adopted as SIST HD 478.2.5 S1:2002)
Title: Classification of environmental conditions - Part 2: Environmental conditions appearing in nature - Section 5: Dust, sand, salt mist
Organization: CLC / CENELEC

This standard presents the characteristics of dust, sand and salt mist appearing in nature, and describes the influences from these environmental factors to which products are liable when stored, transported or used. It is a classification guidance document for designers, test engineers and procurement specialists who need to account for natural particulate and saline environments in product specification and protection.

Key Topics

• Characterisation of environmental agents: Describes natural occurrence and behaviour of dust, sand and salt mist, including their physical and chemical aspects as they affect products.
• Environmental influences: Explains how exposure during storage, transportation and use can affect materials, components and assemblies (e.g., abrasive wear, contamination, corrosive attack).
• Classification approach: Provides a framework for classifying severity or types of dust, sand and salt-mist environments to support consistent specification of environmental requirements.
• Specification input: Intended to support selection of protective measures, materials and design features by clarifying expected environmental conditions.

Note: the standard focuses on classification and descriptive guidance rather than prescriptive laboratory test methods.

Applications

This standard is useful for:

• Design and reliability engineers specifying environmental robustness for electronics, mechanical systems and enclosures.
• Manufacturers and OEMs that need to define storage, transport and operational environmental requirements.
• Test laboratories and quality teams when planning environmental testing and aligning test levels with real-world dust/sand/salt-mist exposures.
• Procurement and asset managers writing contracts and conditions for equipment intended for coastal, desert or dusty inland locations.

Practical uses include developing protective enclosures, selecting corrosion-resistant materials and planning maintenance strategies to mitigate dust, sand and salt-mist impacts.

Related standards

• Other parts of the HD 478 classification series (Part 2 other sections) for comprehensive environmental condition classification.
• Commonly used alongside environmental testing standards (for example, general environmental testing standards such as IEC 60068) and corrosion or ingress-protection guidance when defining test programs and acceptance criteria.
