Understanding Full Material Disclosure: A Closer Look at IPC 1752, IPC 1754, and IEC 62474

Full Material Disclosure (FMD) is a concept that is gaining traction in the manufacturing business world. This concept refers to the disclosure of all materials used in a product or service, including any hazardous substances. It is becoming increasingly important for companies to be transparent about the materials they use in order to ensure safety and reduce environmental impact.

The idea of full material disclosure is to create an environment where businesses are held accountable for the materials they use. This requires companies to disclose information about the ingredients, parts, and components used in the production of their products. This includes the presence of hazardous substances, such as lead, mercury, and other toxins.

FMD standards have been established to ensure that companies are providing accurate and complete information about their products. These standards require companies to disclose all materials used in the production of their products and the processes used to create them. Companies that adhere to these standards demonstrate their commitment to transparency and sustainability, and can help build trust with their customers. Common FMD data exchange standards that are used today include IPC 1752A, IPC 1754 and IEC 62474.

• IPC-1752A is commonly used for REACH and RoHS data exchange and has four classes (Class A, Class B, Class C, and Class D).
• IPC-1754 is tailored for Aerospace and Defense data exchange and has three classes (Class E, Class F, and Class G).
• IEC 62474, developed by the International Electrotechnical Commission, enables users to exchange 100% of product information in XML format, covering substances listed in the Declarable Substance List (DSL).

IPC-1752A Standard: An Overview of Material Declaration for the Electronics Industry

The IPC-1752A standard is a critical standard in the electronics industry, providing guidelines for material declaration in electronic products. The IPC-1752A standard was first introduced in 2006 by the Association Connecting Electronics Industries (IPC) as a means of standardizing the format and content of material declarations. The standard was later revised in 2008, and the most recent revision was in 2018. The standard has evolved over the years, incorporating changes in regulations and industry best practices.

The purpose of the IPC-1752A standard is to provide a standardized format for material declarations, ensuring that suppliers and manufacturers can communicate information about the materials used in their products effectively. The standard aims to provide consistency and clarity in material declarations across the industry, enabling supply chain stakeholders to evaluate and manage environmental and health risks associated with electronic products.

The IPC-1752 standard establishes four classes of Material Declarations. These classes are based on the level of detail provided in the declaration.

• Class A: This class is the most basic level of declaration, where the supplier simply states whether their product meets a defined query list.
• Class B: This class provides a higher level of material declaration, which includes information on the substances that are intentionally added to the product, as well as any substances that are known to be present above certain threshold levels.
• Class C: This class provides a product-level material declaration based on the JIG-101 material list and REACH substance list.
• Class D: This class provides a full material disclosure (FMD) at the homogeneous level, which means that the declaration includes information on all substances in each homogeneous material within the product.

Benefits of using IPC-1752A Standard:

• Enables supply chain stakeholders to effectively manage environmental and health risks associated with electronic products.
• Promotes transparency and sustainability in the industry by providing a standardized format for material declarations.
• Helps companies to identify potential problems before they become an issue, enabling them to take corrective action proactively.

IPC-1754: Standard Format for Material Data Exchange in Aerospace and Defense Industry

The Aerospace and Defense industry is highly regulated, with strict requirements for the materials used in its products. The industry must comply with various global regulations, including EU RoHS, REACH, China RoHS and TSCA, to ensure that the products are safe and environmentally friendly. IPC-1754 helps companies in the industries with deep supply chains and complex bills of materials comply with these regulations by providing a standard format for exchanging material data. This ensures that all necessary information is communicated accurately and efficiently, reducing the risk of non-compliance and improving supply chain transparency.

IPC-1754 has three different classes, each class corresponds to a different level of material disclosure, with Class E being the most basic and Class G being the most comprehensive.

Class E:

• Supplier responds to industry-defined statements regarding substances in their product(s).
• Supplier responds with "True," "False," or "Unknown" responses.

Class F:

• Supplier reports on the presence of industry-defined Declarable Substances List (DSL) substances in their product(s).
• Supplier also reports on the presence of DSL substances in processes required for production and/or maintenance of the product(s).

Class G:

• Supplier submits declaration data for DSL substances and any other substances up to a full substance declaration.
• Supplier may also report on substances used in processes required for production, operations, maintenance, repair, and/or refurbishment of their product(s).

Furthermore, IPC-1754 has several appendices that provide additional guidance and information related to the data exchange process.

Benefits of IPC-1754:

• Improved Compliance: By providing a standardized format for exchanging material data, IPC-1754 helps companies comply with global regulations and customer requirements, reducing the risk of non-compliance.
• Enhanced Supply chain Transparency: The standard improves supply chain transparency, enabling companies to make informed decisions about the materials they use in their products.
• Increased Efficiency: IPC-1754 streamlines the process of exchanging material data, reducing the time and resources needed to manage material data and improving overall efficiency.
• Competitive Advantage: By complying with global regulations and demonstrating supply chain transparency, companies in the Aerospace and Defense industry can gain a competitive advantage and improve their reputation with customers and stakeholders.

IEC 62474 Standard: The Key Standard for Hazardous Substance Disclosure in Electrical and Electronic Products

The International Electrotechnical Commission (IEC) is an international standards organization that develops and publishes standards for electrical, electronic, and related technologies. One of its most important standards is IEC 62474, which deals with product material declaration. The purpose of IEC 62474 is to facilitate the exchange of information on hazardous substances in electrical and electronic products, specifically those listed in the Declarable Substance List (DSL). The DSL is a list of hazardous substances that are regulated by various national and international regulations, including the European Union's RoHS Directive and the REACH Regulation.

Requirements of IEC 62474

IEC 62474 requires organizations to provide material declaration information for each electrical and electronic product they manufacture, assemble, or supply in a standardized format, using the eXtensible Markup Language (XML) data exchange format. This information must include the identity, concentration, and location of any hazardous substances present in the product, as well as any exemptions that may apply. The standard provides guidelines for the exchange of information on the management of hazardous substances throughout the product lifecycle, from design and manufacturing to end-of-life disposal.

Benefits of IEC 62474:

• Provides a common framework for the exchange of information on hazardous substances in electrical and electronic products, which helps to streamline communication and reduce confusion.
• Promotes transparency and accountability in the supply chain, enabling organizations to make informed decisions about the products they use and the suppliers they work with.
