What is ISO 21809-3:2016 ?

ISO 21809-3:2016 is a technical specification that outlines the method for measuring the physical thickness of a coating applied on a substrate. It is an essential parameter that affects the functionality, durability, and appearance of coated products. To ensure the desired performance of coatings, it is crucial to maintain the specified thickness within acceptable limits, as defined by ISO 2284:2016.

ISO 2284:2016 provides a standardized approach to measure and evaluate coating thickness accurately. The standard outlines various non-destructive measurement techniques and specifies the requirements for their calibration and verification. These techniques include magnetic, eddy current, ultrasonic, and X-ray methods. By following the guidelines outlined in ISO 2284:2016, industries can ensure consistency and reliability in coating thickness measurements.

Moreover, ISO 2284:2016 also addresses the selection of appropriate instruments, the preparation of test specimens, and the interpretation of measurement results. It emphasizes the importance of proper training for operators who perform coating thickness measurements. Adhering to this standard enables organizations to meet customer expectations, comply with regulations, and improve the overall quality of their products.

ISO 17827-3:2016 is a technical specification that defines the method for measuring the performance of writing instruments. As technology advances, it becomes increasingly important to have standardized testing methods to evaluate the quality and performance of various products, including writing instruments. ISO 17827-3:2016 provides manufacturers and users with a set of guidelines and parameters for assessing the performance of different types of writing instruments.

The purpose of ISO 17827-3:2016 is to establish a uniform and objective approach to evaluating the performance of writing instruments. It sets out specific requirements and test methods for measuring essential characteristics such as ink flow, writing length, and line width consistency. These parameters help determine the usability, durability, and overall quality of a writing instrument. By adhering to these standards, manufacturers can ensure that their products meet minimum requirements, while consumers can make informed decisions when purchasing writing instruments.
