1. What information does the U-Spec provide?

The U-Spec provides data on all materials present within the unit product, as mass (g) and as % of unit total mass. If a material is not listed it is not present in the product. However, in some cases trace substances-of-concern or C2E List may be declared in the U-Spec.

2. Is the U-Spec a recognised standard?

The U-Spec is based on the principles of “Good Declaration Practice” (GDP). Standardization has been submitted to IEC (DKE K135, DIN 19220 (CDV 7/307 IEC)). The DIN 19220 national standard defines the process of declaration of substances in products of the Electrical and Electronic Industry without addressing detailed named substances. It organizes a hierarchy and data structure for reporting/declaration purposes. An international IEC standard is expected by 2005.

3. Which companies recognize the U-Spec as a means of materials declaration?

Audi, BMW, DaimlerChrysler, Magneti Marelli, Siemens VDO, VDA, AMD, Bosch, Fujitsu Semicon, Freescale (formerly Motorola), Panasonic, Philips, Texas Instruments, STMicroelectronics, Johnson Control, Osram, Murata, Vishay, VOGT electronic and many more have accepted the U-Spec as the standard for the declaration of material content in semiconductor & passive products.
