NATIONAL BUREAU OF STANDARDS

The National Bureau of Standards' was established by an act of Congress March 3, 1901.The Bureau's overall goal is to strengthen and advance the Nation's science and technologyand facilitate their effective application for public benefit. To this end, the Bureau conductsresearch and provides: (1) a basis for the Nation's physical measurement system, (2) scientific

and technological services for industry and government, (3) a technical basis for equity in trade,

and (4) technical services to promote public safety. The Bureau consists of the Institute forBasic Standards, the Institute for Materials Research, the Institute for Applied Technology,

the Institute for Computer Sciences and Technology, and the Office for Information Programs.

THE INSTITUTE FOR BASIC STANDARDS provides the central basis within the UnitedStates of a complete and consistent system of physical measurement; coordinates that system

with measurement systems of other nations; and furnishes essential services leading to accurate

and uniform physical measurements throughout the Nation's scientific community, industry,

and commerce. The Institute consists of a Center for Radiation Research, an Office of Meas-urement Services and the following divisions:

Applied Mathematics — Electricity — Mechanics — Heat — Optical Physics — NuclearSciences " — Applied Radiation " — Quantum Electronics — Electromagnetics " — Timeand Frequency " — Laboratory Astrophysics " — Cryogenics

THE INSTITUTE FOR MATERIALS RESEARCH conducts materials research leading toimproved methods of measurement, standards, and data on the properties of well-characterized

materials needed by industry, commerce, educational institutions, and Government; provides

advisory and research services to other Government agencies; and develops, produces, anddistributes standard reference materials. The Institute consists of the Office of Standard

Reference Materials and the following divisions:

Analytical Chemistry — Polymers — Metallurgy — Inorganic Materials — ReactorRadiation — Physical Chemistry.

THE INSTITUTE FOR APPLIED TECHNOLOGY provides technical services to promotethe use of available technology and to facilitate technological innovation in industry and

Government; cooperates with public and private organizations leading to the development of

technological standards (including mandatory safety standards), codes and methods of test;

and provides technical advice and services to Government agencies upon request. The Instituteconsists of a Center for Building Technology and the following divisions and offices:

Engineering and Product Standards — Weights and Measures — Invention and Innova-tion —• Product Evaluation Technology — Electronic Technology — Technical Analysis— Measurement Engineering — Structures, Materials, and Life Safety * — BuildingEnvironment * — Technical Evaluation and Application * — Fire Technology.

THE INSTITUTE FOR COMPUTER SCIENCES AND TECHNOLOGY conducts researchand provides technical services designed to aid Government agencies in improving cost effec-tiveness in the conduct of their programs through the selection, acquisition, and effective

utilization of automatic data processing equipment; and serves as the principal focus within

the executive branch for the development of Federal standards for automatic data processing

equipment, techniques, and computer languages. The Institute consists of the following

divisions:

Computer Services — Systems and Software — Computer Systems Engineering — Informa-tion Technology.

THE OFFICE FOR INFORMATION PROGRAMS promotes optimum dissemination andaccessibility of scientific information generated within NBS and other agencies of the FederalGovernment; promotes the development of the National Standard Reference Data System and

a system of information analysis centers dealing with the broader aspects of the National

Measurement System; provides appropriate services to ensure that the NBS staff has optimumaccessibility to the scientific information of the world. The OflRce consists of the followingorganizational units:

Office of Standard Reference Data — Office of Information Activities — Office of TechnicalPublications — Library — OflSce of International Relations.

Reference tables for several thermoelements versus platinum (Pt-67) are given with valuesof the thermoelectric voltage as a function of temperature in degrees Fahrenheit. Only tables forstandard letter-designated thermoelements are included: Types BP, BN, JP, JN, KP (same asEP), KN, TP, and TN (same as EN). These tables supplement those given in NBS Monograph125 and were calculated from the power series expansions presented in that Monograph. They arebased upon the absolute electrical units and the International Practical Temperature Scale of1968 (IPTS-68).Key words: Base metal alloys; noble metal alloys; temperature scale; temperature standards;thermoelements ; thermometry.

Introduction

Reference tables giving corresponding values of

thermoelectric voltage and temperature for thermo-

elements versus platinum provide the manufacturers

of thermocouple wire with a basis for the production

control of their products. The production of thermo-couple wire with thermoelectric properties controlled

to conform to specified tabular values insures inter-

changeability. Reference tables for thermoelements

are also used by science and industry in the testing

and calibration of commercial thermocouple wire and

in the preparation of purchase specifications for it.

This supplement to NBS Monograph 125^ "Thermo-couple Reference Tables Based on the IPTS-68,"

gives reference tables for standard letter-designated

thermoelements versus platinum (Pt-67) with values

of the thermoelectric voltage as a function of tempera-

ture in degrees Fahrenheit. Reference tables for

thermoelements were included in NBS Monograph 125with temperature in degrees Celsius. While the trend

in U.S. industry is expected to be towards the usage

of Celsius temperatures in their transactions, manyindustries are still a number of years away from sucha practice. Therefore, this supplement was preparedto serve the needs of U.S. industry during the transi-

tion period. Its preparation was recommended byCommittee E-20 on Temperature Measurement ofthe American Society for Testing and Materials(ASTM).Tables are given for the following standard letter-

designated thermoelements: Types BP, BN, JP, JN,KP (same as EP), KN, TP, and TN (same as EN).As discussed in NBS Monograph 125, tables for TypeRP, RN, SP, and SN thermoelements are not neces-

sary. Hence, none are included for these types in thissupplement. The tables for Type JP and JN thermo-elements merely give average values for industrial ma-terials, which have a wide variability. They do NOTcontain standardized values. Neither the ASTMnor the ISA recognize Type JP or JN thermo-elements as standardized materials.The typical nominal compositions and representa-

tive trade names for the standard letter-designatedthermoelements are given in table 1. Additional infor-mation on the thermoelements can be found in NBSMonograph 125. Items covered there include recom-mended temperature ranges, special precautions onusage, effect of impurities, and limits of error.The values in these reference tables are calculated

from the power series expansions given in NBS Mono-graph 125. They are based upon the absolute electricalunits and the International Practical TemperatureScale of 1968 (IPTS-68). Values of Fahrenheit tem-perature (tp) are related to International Practical

Celsius Temperatures (fss) by

"The letter designations used in this Supplement follow the recommendations of ASTM Committee E-20 on Temperature(

Measurement. The letter type, e.g.. Type TP, designates the thermoelectric properties of the thermoelement with respect toplatinum, not the precise chemical composition. Thermoelements of a given type may have variations in composition as longas the thermoelectric properties of thermocouples formed from them and their mating thermoelement remain within establishedlimits of error. As indicated in ASTM Standard E230-72, thermocouples and matched thermocouple wire are supplied to es-tablished limits of error. However, limits of error for individual thermoelements with respect to platinum are establishedonly for Types KP and KN. They are supplied, by common practice, to an emf tolerance that is equivalent to one half thelimit of error for the Type K thermocouple.

Registered Trademarks:' Trademark—Wilbur B. Driver Co." Trademark—Kanthal Corp.* Trademark—Driver-Harris Co.* Trademark—Hoskins Manufacturing Co.The use of trade names does not constitute an endorsement of any manufacturer's products. All materials manufactured in

compliance with the established thermoelectric voltage standards are equally acceptable.
