IEC 62368-1

IEC 62368-1 is an international safety standard that defines a unified framework for evaluating risks associated with audio, video, information, and communication technology equipment. It was developed to address the convergence of technologies that were previously covered by separate safety standards, particularly as digital, networked, and multimedia products began to overlap in function and design.

Rather than focusing on specific construction rules or prescriptive design details, IEC 62368-1 establishes a principles-based model for understanding how energy sources within equipment can lead to injury, damage, or other harm under certain conditions. The standard is structured around identifying types of energy, understanding how that energy can be transferred, and describing the kinds of safeguards that conceptually interrupt or limit harmful outcomes.

Purpose and background

The standard was created by the International Electrotechnical Commission as a successor framework to earlier product-specific safety standards. Historically, information technology equipment and audio-video equipment were evaluated under separate documents, even as the products themselves became functionally indistinguishable. IEC 62368-1 emerged to provide a single, technology-neutral reference that could remain applicable as product categories evolve.

Its purpose is not to redefine what products do, but to redefine how safety is described across a broad and changing equipment landscape. By focusing on underlying hazards rather than legacy product classes, the standard aims to remain stable even as implementation technologies change.

Scope and positioning

IEC 62368-1 applies broadly to equipment intended for use in information processing, communication, and audio-video contexts. This includes products that combine multiple functions or that do not fit neatly into older category boundaries. The standard is positioned as a horizontal safety document, meaning it spans multiple equipment types rather than addressing a single niche.

The scope is intentionally defined at a conceptual level. It outlines the kinds of hazards considered relevant, the general conditions under which those hazards may arise, and the high-level logic by which safety is evaluated. It does not function as a product manual, manufacturing specification, or operational guide.

Hazard-based safety concept

A defining characteristic of IEC 62368-1 is its hazard-based safety approach. Instead of prescribing fixed construction requirements, the standard organizes safety around the interaction between energy sources, the environment, and people or property. Energy is categorized by its potential to cause harm, and safety is framed in terms of preventing or limiting the transfer of that energy to a level that would be injurious.

This conceptual structure allows the standard to describe safety outcomes in a way that is independent of specific technologies. Electrical, thermal, mechanical, chemical, and radiated energy sources are all addressed within a single explanatory framework.

Relationship to earlier standards

IEC 62368-1 is widely recognized as replacing earlier international safety standards that separately addressed information technology equipment and audio-video equipment. Its development reflects a consolidation of safety philosophy rather than a simple revision of technical limits. The standard inherits concepts from its predecessors while reorganizing them into a unified model intended for long-term applicability.

Role within the standards landscape

Within the broader ecosystem of international standards, IEC 62368-1 serves as a reference point for understanding safety expectations for modern electronic equipment. It is frequently cited alongside other IEC and ISO documents that address specific components, environments, or risk domains, but it remains distinct in its focus on overall hazard structure rather than detailed implementation.

The standard’s influence lies in how it frames safety thinking across converged technologies, rather than in prescribing detailed design actions.
