Plastics — Methods of exposure to laboratory light sources — Part 3: Fluorescent UV lamps
ISO 4892-3:2016 specifies methods for exposing specimens to fluorescent UV radiation, heat and water in apparatus designed to simulate the weathering effects that occur when materials are exposed in actual end-use environments to global solar radiation, or to solar radiation through window glass.
The specimens are exposed to fluorescent UV lamps under controlled environmental conditions (…
Radio frequency identification of animals — Code structure
This International Standard specifies the structure of the radio-frequency (RF) identification code for animals. RF identification of animals requires that the bits transmitted by a transponder are interpretable by a transceiver. Usually, the bit stream contains data bits, defining the identification code and a number of bits to ensure correct reception of the data bits. This International…
Fine bubble technology — Evaluation method for determining gas content in fine bubble dispersions in...
This international standard specifies the evaluation methods for hydrogen content in UFB dispersions.
The titration (oxidimetry) method can be used as a quick method to estimate the hydrogen content in hydrogen UFB dispersions. The detection limit is 0.1 mg/L, and the accurate range is between 0.2 mg/L and 1.6 mg/L. The existence of oxidizing or reducing substances in dispersions influences…
