ISO 1247-2-21 Aluminium pigments for paints – חֵלֶק 2: Vacuum metallized aluminium pigments

introduction ISO (הארגון הבינלאומי לתקינה) היא ברית גלובלית של גופי תקינה לאומיים (גופים חברי ISO). פיתוח תקנים בינלאומיים מתבצע בדרך כלל באמצעות ועדות טכניות של ISO. כל מוסד חבר המעוניין בנושא שעליו הוקמה ועדה טכנית זכאי להיות מיוצג באותה ועדה. ארגונים ממשלתיים ולא-ממשלתיים בינלאומיים המקיימים קשר עם ISO מעורבים גם הם בעבודה זו. ISO עובדת בשיתוף פעולה הדוק עם הנציבות האלקטרוטכנית הבינלאומית (חברת החשמל) on all matters [...]

Thermal conductivity tester can also be used to measure the thermal conductivity of liquids and gases

A thermal conductivity tester is an instrument used to measure a substance’s ability to conduct heat, and by accurately measuring thermal conductivity, engineers and scientists can better understand the heat transfer properties of materials and make more informed decisions during design and manufacturing. The tester usually consists of a sample chamber, a heat source, and a temperature detector. During the test, the sample is placed in the sample chamber and heated by a heat source. The temperature detector measures the [...]

Test procedure of thermogravimetric analyzer

A thermogravimetric analyzer is an instrument used to measure the mass change of a substance during heating. It can measure the mass lost or gained during the temperature change of a substance, thus providing information about the thermal stability and thermal decomposition behavior of a substance. In the process of use, it is necessary to strictly follow the operating procedures, and carefully analyze and interpret the test results. The main components include heating system, mass measurement system and gas control [...]
