Rubber latex—Determination of density between 5℃ and 40℃

This standard is a method standard for the determination of latex density, specifying the principles and specific methods for measuring the density of various types of latex within the temperature range of 5°C to 40°C. The standard describes and details two main measurement methods: one based on Archimedes' principle using the buoyancy method (typically employing a direct-reading electronic densitometer as the core instrument), and the other using the classic density bottle method (with its main instruments including a precision density bottle and an analytical balance). This standard is applicable to natural latex, synthetic latex, and other types, providing a unified and scientific testing basis for latex production, quality control, and trade.
