ISO 10289-1999, Methods for testing the corrosion of metals and other inorganic coatings on metal substrates – Test for corrosion tests

preface ISO (International Organization for Standardization) is a global alliance of national standards bodies (ISO member bodies). The development of international standards is usually carried out through ISO technical committees. Each member institution interested in a subject on which a technical committee has been established has the right to be represented on that committee. International governmental and non-governmental organizations liaising with ISO are also involved in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all matters [...]

Application difference between colorimeter and spectrophotometer

How to establish color standards, improve product appearance, color quality control, and computer color matching?Here we have to mention a color detection tool – the color meter. At present, there are many kinds, brands and businesses of color measuring instruments. Some customers are not familiar with color measuring. In the face of various kinds of instruments, will there be a big price gap and different measurement results?Why are some called chromatic aberration instruments, and some called spectrophotometers?What are the differences [...]
