Instruments and apparatus for physical or chemical analysis, viscosity, porosity, expansion, surface tension, heat, sound, or light measurement

1. Scope and Applicability

This PCR applies to the foreground manufacture and factory-gate release of finished instruments and apparatus whose principal function is physical or chemical analysis, measurement or checking of viscosity, porosity, expansion, surface tension or similar properties, or measurement or checking of quantities of heat, sound, or light. It covers electrically powered and non-electrical products only when their declared principal function and product classification fall within CPC 48253.

The PCR is production-data-first. It defines a mass-normalized foreground data package for a declared model or model family. It does not supply default use profiles, service lifetimes, calibration intervals, consumable demand during use, or end-of-life scenarios. Those aspects require a product-specific study or an applicable product-specific rule.
