What is ISO 2106:2019 Anodizing of aluminium and its alloys — Determination of mass per unit area (surface density) of anodic oxidation coatings — Gravimetric method?
ISO 2106:2019 is a standard published by the International Organization for Standardization (ISO) that specifies a gravimetric method for the determination of the mass per unit area (surface density) of anodic oxidation coatings on aluminium and its alloys. The standard applies to anodizing coatings that are formed by the anodic oxidation of aluminium and its alloys in electrolytes, and which are subsequently sealed if required.
The gravimetric method outlined in ISO 2106 involves the following steps:
Cleaning of the sample: The aluminium sample is first cleaned to remove any dirt, grease or other contaminants that may affect the accuracy of the measurement.
Anodizing of the sample: The cleaned sample is then anodized in a suitable electrolyte solution under controlled conditions. The anodizing process creates a porous oxide layer on the surface of the aluminium sample.
Sealing of the sample (optional): If required, the anodized sample is then sealed in a suitable solution to close the pores of the oxide layer.
Weighing of the sample: The anodized and sealed sample is then weighed using a calibrated balance. The difference in weight between the anodized and unanodized samples gives the mass of the anodic oxide coating.
Calculation of surface density: The mass of the anodic oxide coating is then used to calculate the surface density of the coating. Expressed in units of mass per unit area (e.g. g/m2 or mg/cm2).
This standard provides a standardized method for the gravimetric determination of the mass per unit area of anodic oxidation coatings on aluminium and its alloys. This helps to ensure consistent and reliable measurement of the surface density of these coatings. Which is important for quality control and performance evaluation in a range of industries. Including aerospace, automotive, and construction.
Requirements of ISO 2106:2019
ISO 2106:2019 specifies the following requirements for the gravimetric method used to determine the mass per unit area (surface density) of anodic oxidation coatings on aluminium and its alloys:
Sample preparation: The aluminium sample must be properly cleaned to remove any dirt, grease or other contaminants that may affect the accuracy of the measurement.
Anodizing conditions: The anodizing process must be carried out under controlled conditions. Including the use of a suitable electrolyte solution, temperature, and voltage. The anodizing conditions should be selected to produce a coating of uniform thickness and quality.
Sealing conditions (if required): If the anodic oxidation coating is required to be sealed, the sealing process should be carried out under controlled conditions to ensure the integrity of the coating.
Weighing conditions: The anodized and sealed sample must be weighed using a calibrated balance that is capable of measuring the required accuracy.
Calculation of surface density: The mass of the anodic oxide coating is used to calculate the surface density of the coating. Expressed in units of mass per unit area.
Reporting: The results of the gravimetric method should be reported in a manner that is consistent with the requirements of ISO 2106:2019. Including units of measurement and the precision of the measurement.
Benefits of this standard
ISO 2106 provides several benefits for the determination of the mass per unit area (surface density) of anodic oxidation coatings on aluminium and its alloys using the gravimetric method:
Standardization: The standard provides a standardized method for the determination of the surface density of anodic oxidation coatings on aluminium and its alloys. This helps to ensure consistent and reliable measurement of the surface density of these coatings. Which is important for quality control and performance evaluation in a range of industries. Including aerospace, automotive, and construction.
Accuracy: The gravimetric method outlined in ISO 2106:2019 is considered to be one of the most accurate methods for the determination of the mass per unit area of anodic oxidation coatings. So, the use of a calibrated balance helps to ensure that the measurement is carried out with the required level of accuracy.
Efficiency: The standard provides guidance on the appropriate anodizing and sealing conditions, which helps to ensure that the process is carried out efficiently and effectively. This can help to reduce the time and resources required for the measurement while still producing accurate results.
International recognition: The standard is recognized internationally. Which means that companies and organizations around the world can use consistent methods for the determination of the surface density of anodic oxidation coatings on aluminium and its alloys. Thus, this can help to facilitate trade and improve the quality of industrial products across different countries and regions.
Who needs ISO 2106:2019?
