Intentionally added: Substance deliberately used in the formulation of a material or component, where the presence of the substance in the final product provides a specific characteristic, appearance, or quality.Nanomaterials: A natural, incidental, or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50 percent or more of the particles in the number size distribution, one or more external dimensions are in the size range 1 nm–100 nm. In addition, fullerenes, graphene flakes, andsingle-wall carbon nanotubes with one or more external dimensions below 1 nm should be considered as nanomaterials.Non-use: Substance must not be intentionally or unintentionally added and is not detected using current or specified analytical methods.Packaging: Packaging materials used to enclose or protect Apple products during shipment to the end-customer. Packaging shipped to suppliers or OEMs (e.g., tape and reel, trays), and packaging materials used to encapsulate board-level electrical components such as integrated circuits are not included in this definition.Per- and Polyfluoroalkyl Substances (PFAS): Substances that contain one or more perfluoroalkyl moieties, –CnF2n+1.Personal protective equipment (PPE): Equipment for protecting workers from exposure to hazardous materials in the workplace specific to the job function.ppm: Parts per million by weight of a substance; equivalent to 1 mg/kg or 0.0001 percent by weight.Processed chlorine free (PCF): Packaging material produced with pulp from virgin and/or recycled content that has been bleached without any type of chlorine, or that has not been bleached at all. Recycled content may have originally been bleached with chlorine or chlorine derivatives.Test Report Mapping (TRM): The form used to map test reports to declared materials. The TRM form is created in and exported from the FMD Portal and replaces the Material Content Declaration (MCD) form. The TRM form and mapped test reports are collected by Apple manufacturing partners to document compliance of the parts and materials used in Apple products. The information required to create a TRM form for Apple’s manufacturing partners is the foundation of an FMD declaration required by Apple. These processes have been harmonized to eliminate duplicative work and align requirements across the Apple supply chain.Totally chlorine free (TCF): Packaging material produced with pulp from virgin content that has been bleached without any type of chlorine, or that has not been bleached at all. material.
