IEC 60107-4:1988/AMD1:1999 is a technical amendment connected to the parent document IEC 60107-4:1988, addressing recommended methods of measurement on receivers for television broadcast transmissions. It specifically concerns electrical measurements on multichannel sound television receivers using the two-carrier FM-system, making it relevant for test planning, documented evaluation, and compliance workflows where receiver performance must be assessed against a defined method. For engineering teams and laboratories, IEC 60107-4:1988/AMD1:1999 helps align technical review activities with a consistent measurement reference.

Purpose of IEC 60107-4:1988/AMD1:1999

The purpose of IEC 60107-4:1988/AMD1:1999 is to modify the parent measurement guidance for television broadcast receivers so that electrical testing of multichannel sound designs using the two-carrier FM-system can be handled in a clearer and more consistent way. As an amendment, it should be used together with IEC 60107-4:1988 during technical assessment, laboratory evaluation, and conformity assessment preparation. It supports organizations that need a reliable reference for comparing results across testing workflows and engineering documentation.

Compliance applications of IEC 60107-4:1988/AMD1:1999

This reference is useful where receiver testing, product evaluation, or certification support depends on defined measurement methods for broadcast television equipment. It may be applied in laboratory environments, quality workflows, and procurement review when teams need to confirm that multichannel sound television receivers are assessed using the correct electrical measurement approach. IEC 60107-4:1988/AMD1:1999 is especially relevant for organizations maintaining technical compliance records, preparing test reports, or validating operational consistency across repeated measurements.

Benefits of IEC 60107-4:1988/AMD1:1999

Using IEC 60107-4:1988/AMD1:1999 helps reduce ambiguity in measurement practice by tying the updated requirements to a specific parent document and test context. That supports better testing consistency, more dependable engineering validation, and stronger conformity assessment preparation. It can also improve procurement decisions by giving teams a clear technical document for review against internal specifications and external compliance expectations. For organizations managing risk management and documented evaluation, it provides a focused reference for electrical measurement methodology.
