NIST XCOM: Photon Cross Sections Database - SRD 8
Data provided by National Institute of Standards and Technology
A web database is provided which can be used to calculate photon cross sections for scattering, photoelectric absorption and pair production, as well as total attenuation coefficients, for any element, compound or mixture (Z <= 100) at energies from 1 keV to 100 GeV. XCOM provides two forms of output: (a) tables which correspond closely in format to existing tables in the literature; (b) graphical display of the tabular data.

NIST/ASME Steam Properties Database - SRD 10
Data provided by National Institute of Standards and Technology
The NIST/ASME Steam Properties Database is based upon the International Association for the Properties of Water and Steam (IAPWS) 1995 formulation for general and scientific use for the thermodynamic properties of water, this updated version provides water properties from the international standards over a wide range of conditions. Version 3.0 incorporates new IAPWS standards adopted in 2008 for the viscosity and for the melting and sublimation curves and in 2011 for the thermal conductivity.

NIST/EPA Gas-Phase Infrared Database JCAMP Format - SRD 35
Data provided by National Institute of Standards and Technology
This data collection contains 5,228 infrared spectra of different compounds along with chemical structures for most of them. Spectra are provided on a CD-ROM in the JCAMP-DX (Joint Committee for Atomic and Molecular Physical Data 'Data Exchange') format. Chemical structures are provided in the MOL-file format. The IR data originated from two sources, from the so-called 'EPA Vapor-Phase IR Library' and from NIST laboratories.

NIST Heat Transmission Properties of Insulating and Building Materials Database - SRD 81
Data provided by National Institute of Standards and Technology
NIST has accumulated a valuable and comprehensive collection of thermal conductivity data from measurements performed with a 200-mm square guarded-hot-plate apparatus. The guarded-hot-plate test method is arguably the most accurate and popular method for determination of thermal transmission properties of flat, homogeneous specimens under steady state conditions. Several organizations, including ASTM and ISO, have standardized the method.
