Causes of Variation in Chemical Analyses and Physical Tests of Portland Cement

Causes of Variation in Chemical Analyses and Physical Tests of Portland Cement

Date: April 27, 1961
Creator: Bean, B. Leonard & Dise, John R.
Description: Report discussing variations in comparative tests of portland cements that could lead to the rejection of a material fully conforming to specification requirements, or the acceptance of a material with undesirable chemical or physical properties. Many of the causes for variation in chemical analyses and physical test results are listed in this discussion, and remedies for some of the more frequently encountered deficiencies in apparatus and methods are suggested.

Colors of Signal Lights: Their Selection, Definition, Measurement, Production, and Use

Colors of Signal Lights: Their Selection, Definition, Measurement, Production, and Use

Date: April 3, 1967
Creator: Breckenridge, F. C.
Description: Report discussing the selection, specifications, and use of signal-light colors. It discusses the nature of the problem, and the mathematical representation, recognition, production, control, and use of such colors. The characteristics of different types of chromaticity boundaries and the purpose and effect of the requirement for similarity of chromaticity characteristics are given special consideration. The treatment is varied according to the intended use. The discussion of the control of colors and the section on the use of colors are nontechnical, whereas the section on the production of signal colors is designed for the colorimetrist who is faced with the problem of selecting limit filters or drafting a specification.

Corrected Optical Pyrometer Readings

Corrected Optical Pyrometer Readings

Date: April 21, 1961
Creator: Poland, D. E.; Green, J. W. & Margrave, J. L.
Description: Report presenting a table of corrected optical pyrometer readings which enables optical pyrometer users to convert observed temperature immediately to the true temperature, if the effective emissivity of the material being observed is known. The table gives observed temperatures from 1,000 to 3,000ºK in increments of 5 degrees, from 3,000 to 5,000ºK in increments of 10 degrees, from 5,000 to 10,000ºK in increments of 50 degrees, and from 10,000 to 39,900ºK in increments of 100 degrees. For these, true temperatures are tabulated for 49 emissivities ranging from 0.02 to 0.98 in increments of 0.02.
