: Soil identification and evaluating the load-bearing capacity of subgrade layers under heavy traffic.
The CIE 542 is a colorimetry standard developed by the International Commission on Illumination (CIE), a non-profit organization that aims to promote international cooperation and standardization in the field of lighting and color. The CIE 542 standard provides a framework for measuring and expressing the color properties of objects, materials, and light sources.
Many university libraries and IHS Markit (now part of S&P Global) hold the historical CIE 542 document. For most practical purposes, the IEC 60381 series is the legally authoritative replacement. cie 542
First and foremost, a critical clarification: is not an active, standalone standard published by the International Commission on Illumination (CIE), which typically handles lighting and colorimetry. Instead, "CIE 542" is most commonly an industry shorthand, a typographical variant, or a legacy reference to IEC 60542 (formerly known as CIE 542 in certain European documentation systems, particularly in French or German contexts).

In the world of industrial instrumentation, process control, and automation, standards are the silent guardians of safety, reliability, and interoperability. Among the myriad of technical documents published by the International Electrotechnical Commission (IEC) and other bodies, the term frequently surfaces—often surrounded by confusion. Instead, "CIE 542" is most commonly an industry
