Radio Frequency Measurements for Selected Manufacturing and Industrial Environments using a PN Code Sounding methodology. The resulting measurements include complex impulse responses and spectrum analysis traces. Complex impulse responses were validated using both ray tracing and an outdoor two-ray reference facility. This data is meant to serve as a reference of how radio waves at 2.4 GHz and 5 GHz propagate in industrial environments.

SRM 1297 Stainless Steel (SAE 201) - 'This Standard Reference Material (SRM) is intended for use in optical emission and x-ray spectrometric methods of analysis. It is in the form of a disk approximately 32 mm in diameter and 19 mm thick. This data is public in the Certificate of Analysis for this material.

Standard Reference Material 131h Refined Cast Iron - This Standard Reference Material (SRM) is intended primarily for use in validation of chemical and instrumental methods of analysis. It can be used to validate value assignment of in-house reference materials and, if necessary, to calibrate carbon/sulfur analyzers. A unit of SRM 131h consists of a bottle containing 100 g of chips. This data is public in the Certificate of Analysis for this material.

SRM 2452 Hydrogen in Titanium (Nominal Mass Fraction 60 mg/kg) - This Standard Reference Material (SRM) is intended for use in the evaluation of methods and the calibration of equipment used in the determination of hydrogen in titanium alloy. SRM 2452 consists of one bottle containing 10 g of titanium alloy chips. This data is public in the Certificate of Analysis for this material.
