GB/T 24514-2009 《Zinc and/or aluminium based coatings on steel - Determination of coating mass per unit area and chemical composition - Gravimetry, inductively coupled plasma atomic emission spectrometry and flame atomic absorption spectrometry》 Related products

GB/T 24514-2009 for zinc-based and/or aluminum-based platings on steel surfaces. The standard provides for the determination of platings mass and chemical composition per unit area by weight method, inductively coupled plasma atomic emission spectroscopy (AES) method and flame atomic absorption spectroscopy (AAS) method. Platings mass and composition affect the protective performance and service life of steel. This standard provides a unified method for related testing, which helps enterprises control steel platings mass and plays a key role in product quality control and mass improvement in steel manufacturing, construction and other industries.
