ASTM D4214 Measurement of Coating Thickness Laboratory Testing Service: A Comprehensive Guide

The ASTM D4214 Measurement of Coating Thickness testing service is governed by a range of international and national standards, including ISO 2362, ASTM D4214, EN 1353, and TSE 1116. These standards specify the requirements for measuring coating thickness using various methods, including magnetic induction, eddy current, and ultrasound.

The legal and regulatory framework surrounding this testing service is governed by laws and regulations in different countries and regions. For example, in the European Union, the measurement of coating thickness is regulated by the Machinery Directive (2006/42/EC) and the Low Voltage Directive (2014/35/EU). In the United States, the Occupational Safety and Health Administration (OSHA) requires employers to ensure that employees are not exposed to hazardous materials, including those used in coating processes.

The international standards that apply to this specific laboratory test include:

  • ISO 2362: Metallic and other inorganic coatings - Measurement of thickness by the magnetic induction method

  • ASTM D4214: Standard Test Methods for Coating Thickness and Film Thickness Measurement (Nonmagnetic Coatings)

  • EN 1353: Metallic and other non-metallic coatings - Measurement of coating thickness by the eddy current method

  • TSE 1116: Metallic and other inorganic coatings - Measurement of coating thickness by the magnetic induction method

    • Standard development organizations, such as ASTM International and ISO, play a crucial role in developing and maintaining standards for measurement of coating thickness. These organizations bring together experts from industry, academia, and government to develop and update standards that reflect the latest technology and best practices.

    Standards evolve and get updated regularly to reflect changes in technology, materials, and testing methods. For example, ASTM D4214 was revised in 2018 to include new test methods for measuring coating thickness using advanced technologies such as X-ray fluorescence (XRF) and atomic absorption spectroscopy (AAS).

    Standard compliance is essential for industries that require accurate measurement of coating thickness, including aerospace, automotive, and construction. Compliance with international standards ensures that products meet regulatory requirements and are safe for use.
