IEC 60268-2:1987 defines Sound system equipment. Part 2: Explanation of general terms and calculation methods, making it a practical reference for teams that need consistent terminology and calculation approaches in audio system work. As an original edition, it serves as a primary technical document for engineering review, procurement checks, and conformity assessment tasks where clear interpretation of terms and methods is important. It is especially useful when specifications, test reports, and technical documentation must align across design, verification, and compliance workflows.

Overview of IEC 60268-2:1987

The scope of IEC 60268-2:1987 is centered on clarifying general terms used in sound system equipment and on setting out calculation methods that support technical evaluation. That makes it relevant wherever audio equipment performance, system description, or documentation needs to be interpreted in a consistent way. For engineering teams, it can support technical review, documented evaluation, and more uniform comparison of results across projects, laboratories, and procurement specifications. The edition and publication date provide useful context for traceability in controlled document sets.

Compliance applications of IEC 60268-2:1987

This reference is typically consulted in sound system design, product evaluation, and laboratory evaluation workflows where terminology and calculation conventions affect reported results. It may be used when preparing technical documentation for audio equipment, comparing supplier data, or checking that measurements and calculations are presented consistently during verification activities. In procurement and compliance workflows, IEC 60268-2:1987 can help reduce ambiguity when reviewing engineering specifications, test plans, and conformity assessment records connected to sound system equipment.

Importance of compliance with IEC 60268-2:1987

Using IEC 60268-2:1987 in quality workflows helps improve consistency in how sound system terms and calculation methods are applied, which can reduce errors during testing, reporting, and specification review. That consistency supports technical validation, operational consistency, and better alignment between engineering teams, laboratories, and purchasing functions. It can also strengthen regulatory preparation and risk management by making it easier to compare documentation, defend technical assumptions, and maintain traceable compliance references across a product lifecycle.

• Clarifies general terminology used in sound system equipment documentation.
• Supports calculation methods that are relevant to technical review and reporting.
• Helps align test records, product evaluation files, and engineering documentation.
• Useful for procurement and conformity assessment when comparing supplier submissions.
