Preface

Within the framework of the NBS Institute for Materials Research the

area of standard reference materials is a broad and important one, including the preparation, characterization, and distribution of a wide variety of materials in such diverse fields as metallurgy, polymers, and inorganic materials. In carrying out such a program there is much interaction with representatives

of industry and science, beginning with discussions as to which primary stand- ard materials will do most to advance technology, the furnishing of materials and fabrication of samples, and the characterization and certification of the materials by cooperative efforts. The many groups participating in a standards program are very interested in detailed information on specific aspects

of the program—but to date there has been no publication outlet for such

written discussions. To meet this need, the NBS Miscellaneous Publication 260 Series has been reserved for papers in the general area of "standard reference materials." This series begins with a descriptive price list of standard materials available. Succeeding publications present the results of studies and investigations undertaken within the Institute for Materials Research with emphasis on the preparation and characterization of standard reference materials. This subject- oriented series provides a means for rapid dissemination of this detailed infor- mation and we hope will stimulate the use of standard reference materials in science and industry. W. Wayne Meinke, Chief

Office of Standard Reference Materials

Standard Reference Materials

Issued by the National Bureau of Standards

This catalog describes the various Standard Reference Materials issued by the National Bureau of Standards. These materials are used to calibrate measurement systems and

provide scientific information that can be referred to a common base. A schedule of prices and quantities is included for each material, as well as directions for ordering. Listed are the types and compositions of those chemical standards that are presently available. Announcements of new standard reference materials are made in the Federal Register, in

scientific and trade journals, and in the Technical News Bulletin of the National Bureau

of Standards. Changes affecting the current status of the various standards will be indicated by an insert sheet available quarterly from the Bureau. Key words: Analysis, catalog, certificate, characterization, composition, price list, property of material, purity of material, standard reference materials, standards.

1. General Information

1.1. Introduction The standard reference materials issued by the National Bureau of Standards, their prices and

directions for ordering, are given in this publication. All types of well-characterized materials are

available for calibrating measurement systems, and providing scientific information that can be

referred to a common base. Other uses include calibration and standardization of spectrometers, spectrographs, colorimeters, meters, Geiger counters, scintillators, ioniza- tion chambers, pyrometers, polarimeters, refrac- tometers, viscometers, and other laboratory and

plant instruments; checking methods of analysis and analytical techniques; standardization of solutions for volumetric analysis and the develop- ment of new or improved methods of analysis, and the evaluation of the accuracy of analytical methods. The first standard materials issued by the Bureau were a small group of metals certified with respect to their chemical composition. Because of their use as standards in chemical

analysis, the term "Standard Samples" was

applied to them. This term was extended first to similar composition standards, and later to cover materials certified with respect to chemical

purity or to some physical or chemical property. By usage the term has been extended also to certain materials that are issued without certifi- cation of composition or properties. More recently, the term "Standard Sample" has been replaced with the more apt description "Standard Refer- ence Material." In this publication the materials are classified into groups according to the purposes for which

they are intended and the kind of certification,

if any, that applies to them. More than 600

different standards of metals, ores, ceramics,

chemicals, and hydrocarbons are now available

for distribution. About 400 of these are certified for chemical composition. Almost half of the composition standards have been prepared specifically for use in spectroscopic analysis. Other

standard materials include those certified for such

properties as acidity (pH), viscosity, freezing- point, density, index of refraction, and heat of combustion. Each standard material is accompanied by a certificate of characterization. An ex- ample of such a certificate is shown in appendix I.

1.2. Standards Out of Stock The preparation of "renewals" is intended to be completed at the time each kind of material becomes exhausted, but owing to delays encountered in obtaining a proper grade of material, and for other reasons, this is not always possible.

If orders are received for standard reference materials that are out of stock, notice will be

mailed to that effect. The composition of a "renewal" will not usually be identical with that

of its predecessor, but it will be quite similar, especially with regard to the characteristic constituent or constituents, and generally the "re- newal" can be used in place of its predecessor.

1.3. New Standards When new standard reference materials or re- newals of old ones are issued, announcement will be made in scientific and trade journals, in the Standard Materials column of National Bureau

of Standards Technical News Bulletin, and in the Federal Register. This information will also be

given in the Quarterlv insert sheet for this catalog (NBS Misc. Publ. 260) available from the Bureau.

If you wish to be placed on a mailing; list to receive these inserts as they are issued, please complete the post card included at the end of

this catalog, detach it, and mail to the National Bureau of Standards. The Office of Standard Reference Materials welcomes suggestions for new standard materials. While it is not possible to produce all of the materials that will be requested by science and industry throughout the country, we will try to make those for which there is the greatest

demonstrated need. Thus we have prepared a "Guide for the Submission of Requests for the Development of New or Renewal Standard Ref- erence Materials" which delineates Bureau pol- icy in this area and establishes a standard format

for such requests. This "Guide" is reproduced

for your information in appendix II (page 40)

of this publication. NBS calibrating and testing services for a wide variety of standards and

instruments are given in a separate publication; NBS Misc. Publ. 250, Calibrating and Testing Services, price $1.00.

2. Purchase Procedure

2.1. Identification of Standards

The standards are listed by groups; the numbers represent the issuance of the first repre- sentative sample of each kind. Renewals are in- dicated by the original number with an added

letter to denote the relation. Thus, 11a is the

first, lib the second, 11c is the third renewal of No. 1 1 Basic Open-Hearth Steel, 0.2 percent

carbon. In this way, a particular number always

represents a material of fixed or approximately

fixed composition. Although renewals are not

identical with their predecessors, they generally can be used in place of them.

2.2. Ordering

Orders should be addressed to the Office of Standard Reference Materials, National Bureau

of Standards, Washington, D.C. 20234, and

should give the amount, catalog number and name of the standards requested. For example:

150 g of No. llh Basic Open-Hearth Steel, 0.2 percent C. The list of standard materials, their numbers, prices and composition or intended

use are given on the pages which follow. These

materials are distributed only in the units listed. Acceptance of orders does not imply acceptance

of any provision set forth in this order contrary

to the policy, practice or regulations of the National Bureau of Standards in the U.S. Government. Prices as listed in this catalog are subject to change without notice. Price changes, when made are first announced in the Federal

Register. Prices in effect at time of shipment

will be billed to the purchaser.

2.3. Terms and Shipping

2.3.1. Domestic Shipments Shipments of material (other than hydrocarbons, organic sulfur compounds and radio- active standards) intended for the United States, Mexico, and Canada are normally shipped pre- paid parcel post (providing that the parcel does not exceed the weight limits as prescribed by

Postal Laws and Regulations) unless the pur- chaser requests a different mode of shipment, in which case the shipment will be sent collect. It is impractical for the Bureau to prepay shipping charges and add this cost to the billing invoice. Hydrocarbons, organic sulfur compounds, rubber compounding materials, viscometer calibrating

oils, and radioactive standards are shipped express

collect. No discounts are given on NBS Standard

Reference Materials.

2.3.2. Foreign Shipments Small shipments will be forwarded as a U.S. Government shipment via International Parcel

Post, providing that the parcel does not exceed

the weight limits as prescribed by Postal Laws

and Regidations to foreign countries. Shipments

exceeding the parcel post weight limit must be handled through an agent (shipping or brokerage

firm) located in the United States as designated by the purchaser. Parcels will be packed for overseas shipment and forwarded via express collect to the U.S. firm designated as agent.

2.3.3. Payment for Foreign Orders Remittances in payment of foreign orders must

be made payable to the National Bureau of Standards, and are required in advance. These

remittances must be drawn on a bank in the United

States and payable at the standard rate of U.S.

currency.

3. Standards of Certified Chemical Composition

3.1. Steels (Chip Form)

This group of standard reference materials has been prepared for the steel industry primarily for use in checking

chemical methods of analysis both for production control, and for customer acceptance. The group consists of nominal

composition steel alloys and is selected to provide a wide range of analytical values for the various elements which are

of vital concern to the chemist. They are furnished in 150 g units of chips, usually sized between 16- and 40-mesh sieves, prepared from selected portions of commercial ingots. Certificates of analyses, provided with these standards, give the composition as determined at the National Bureau

of Standards, and most also include values obtained by industrial and other outside laboratories cooperating in the cer- tification of the standards.

3.2. Steels (Solid Form)

Several groups of standards have been prepared and designed to meet the basic needs of the steel industry for analytical control primarily by optical emission and x-ray spectroscopic methods of analysis. Both nominal composition and

analytical range standards are provided for ingot iron, low-alloy steel, stainless steel, and tool steel. These standard reference materials are furnished in three basic forms: (1) rods %i in in diameter, 4 in long (400 series)

;

(2) rods x/i in in diameter, 2 in long (800 series); and (3) disks 1^« in in diameter and either % in or % in thick (1100

series or D 800 series). The 400 series is intended for optical emission spectroscopic methods of analysis utilizing the "point-to-point" technique. The 800 and 1100 series are intended for "point^to-plane" optical emission spectroscopic methods of analysis. The D 800 series, and the 1 100 series also, are intended for x-ray spectroscopic methods of analysis. Because of the special homogeneity requirements, most of these materials have been prepared by using the most modern techniques of melting, casting, fabrication, and heat treatment to insure adequate uniformity of composition. The standards are furnished with Certificates of Analyses which give the composition as determined at the National Bureau of Standards; some also include values by outside laboratories cooperating in the certification of the standards. (Values in parentheses are not certified, but are given for additional information on the composition.)

3.2.5. Ferrous Materials (For Oxygen and Nitrogen) These standards are intended to provide materials for checking analytical methods for determining oxygen and

nitrogen only. SRM No. 1041 is supplied in rods 1 in in diameter and 3 in long weighing approximately 300 g. Because the rods

are radially segregated, care must be taken so that the sample used for an analysis represents the entire cross section of the rod. SRM Nos. 1090 to 1092 are intended primarily to provide standards for determining oxygen by the vacuum fusion or inert gas fusion methods. They are supplied in rods 4 in long. Nos. 1090 and 1092 are }i in in diameter and 1091 is Yte in in diameter. (Note that two titanium-base SRMs, Nos. 355 and 356, section 3.11.3, page 18, also are available

for the determination of oxygen.)

Details on the preparation and analysis of SRMs 1090, 1091, and 1092 are given in NBS Misc. Publ. 260-14 "Determination of Oxygen in Ferrous Materials SRM 1090, 1091, and 1092" by Oscar Menis and J. T. Sterling. (See.inside back cover for ordering instructions.)

3.4. White Cast Irons (Solid Form)

These cast iron SRMs were prepared for use in analytical control by rapid instrumental methods. Although often employed in x-ray spectroscopic analysis, they are particularly useful for calibrating vacuum optical emission spectrometers because they permit the determination of carbon, phosphorus, and sulfur, in addition to the metallic elements. These materials are furnished as chill-cast sections approximately l>i in sq and )4 in thick. Details of the preparation and intended use of the standards are in the NBS Misc. Publ. 260-1, Preparation of NBS White Cast Iron Spectrochemical Standards by R. E. Michaelis and LeRoy L. Wyman. (See inside back cover for ordering instructions.)

3.7. Copper-Base Alloys (Solid Form)

Several groups of copper-base alloy standards have been prepared to provide for analytical control by rapid in- strumental methods in the copper industry. These standards are intended primarily for calibration of optical emission and x-ray spectroscopic equipment, and have been prepared in chill-cast form for the producer, and wrought form for the consumer—both forms having identical (or nearly identical) composition. Seven principal copper-base alloys are covered by a "nominal-composition" together with a low- and a high-composition standard. To make the standards more

widely applicable, a number of trace elements were purposely added to the cartridge brass series, and these have been

certified. Three beryllium copper standards have been prepared to be representative of the nominal composition for CABRA alloys 165-170, 25-172, and 10-175, respectively. The materials are furnished in two basic forms: (1) unidirectional chill-cast samples (CI 100 series) in the form of

solid sections 1% in sq, J£ in thick, and (2) wrought material (either forged or hot-extruded) in the form of disks 1% in

in diameter, % in thick (1100 series). Details on the preparation and use of the seven principal copper-base alloys are fiven in NBS Misc. Publ. 260-2, Preparation of NBS Copper-Base Spectrochemical Standards by R. E. Michaelis, LeRoy Wyman, and Richard Flitsch. Methods of chemical analyses employed at NBS for these alloys are described in NBS

Misc. Publ. 260-7 by R. K. Bell. The beryllium copper standards were prepared similar to the other copper-base alloys. Further details on the analysis, where different, will appear in a subsequent 260 series publication. (Values in parentheses are not certified, but are given for additional information on the composition.)

3.8. High Temperature Alloys (Solid Form)

High temperature alloy standards have been prepared to meet the critical needs of industry and government, partic- ularly the Department of Defense and the aerospace industries, for alloys of this type. These standards are useful

in instrument calibration, primarily for optical emission and x-ray spectroscopic methods of analysis. Some samples are issued in the wrought form (1184, 1185, 1193, 1194, and 1195); some as disks 1% inches in di- ameter and s/i in thick; and others in chill-cast form (1190, 1204, and 1205) as sections l}i inches sq. and % in thick. (Values in parentheses are not certified, but are given for additional information on the composition.) SRM

3.13. Zinc-Base Die-Casting Alloys and Zinc Spelter (Solid Form)

These standards are intended for instrument calibration by optical emission spectroscopic methods of analysis primarily for ASTM alloys AG40A and AC41A. The materials are supplied as bar segments 1% in square and % in thick. They were prepared by a continuous chill-casting process. The certified portion of each standard is that part included between M« in and >>i« in from each side of the square sample. The center core, Ms in square; and the outer portion, Me in from the outer surface, are parts which may differ in composition for some elements from the certified portion, and should not be used. A Certificate of Analysis supplied with the standard gives the chemical composition determined, at the National Bureau of Standards, and all except the spelter include values obtained by outside laboratories cooperating in the certifi- cation of the standards.

(Values in parentheses are not certified, but are given for additional information on the composition.)

These standard hydrocarbon blends were prepared for calibration of mass spectrometric and other instrumental procedures used in the analysis of gasolines, naphthas, and blending stocks. Each SRM comprises ten ampoules, each ampoule containing about 0.03 ml of the blend. To retard the effects of possible fractionation of the components after the ampoule is opened, each ampoule is intended to provide material for only one calibration analysis. For the individual components present in the mixtures in the amount of 10 percent or less, the limits of error in composition are not greater than ± 0.01 percent and for components present in over 10 percent, the limits of error are not greater than ± 0.10 percent. The composition of each blend is given in volume percent. A certificate is supplied with each of these samples.

These standards have been established to provide the rubber industry with standard materials for rubber compounding. They are useful for the testing of rubber and rubber compounding materials in connection with quality control of raw

materials and for the standardization of rubber testing. Each material has been statistically evaluated for uniformity by mixing rubber compounds and vulcanizing them in accordance with ASTM Designation D-15 and determining the stress-strain properties of the resulting vulcanizates.

Certificates are issued for the rubbers since the properties of different lots are not the same. Replacement lots of rubber compounding materials impart essentially the same characteristics to rubber vulcanizates so that certificates are not issued

for these materials.

4.10. Color Standards for Spectrophotometer-Tristimiilus Integrator Systems

This set of 5 transparent colored glass standards is available to check the performance of spectrophotometer-tristimulus

integrator systems, the automatic recording and computing devices used in routine color measurements. The set consists of

five 2-inch square glass filters (approximately 3.0 mm thick) with polished faces. A chart of tristimulus values for CIE

sources A, B, and C, representing incandescent-lamp light, noon sunlight, and average daylight; and a detailed report on the changes in tristimulus values caused by errors in the 100-percent and zero adjustments of the photometric scale, wavelength errors, slit-width errors, errors due to stray energy, and inertia errors of the recording mechanism, are furnished with

each set of glasses. Through the use of these standards the user of a spectrophotometer-integrator combination will be able not only to determine when the instrument goes out of adjustment, but also from the pattern of the discrepancies between measured and reported tristimulus values, to obtain some clue as to the type of maladjustment. The glasses are available only in sets of five.

4.11. The ISCC-NBS Centroid Color Charts

The ISCC-NBS centroid colors are available to illustrate a characteristic color for each of the ISCC-NBS color-name

blocks in the Color Names Dictionary, NBS Circular 553. This chart set along with the table containing the history of the color-names project, the centroid number and the Munsell renotation of each of the 251 color chips included, constitute the Supplement to the Color Names Dictionary. Each chart set contains 18 constant-hue centroid color charts. These centroid

colors represent a systematic sampling of the whole color solid, each color of which has been carefully measured. Each

centroid color has its own specification and can be used as a color standard. The centroid color charts can also be used for approximate color specifications wherever the ISCC-NBS color designations are applicable, for statistical studies of trends

in industrial color usage, or for planning lines of merchandise intended to have coordinated colors. SRM Nos. Kind Price per set 2106 $5.00

Standard Reference Materials 1018 and 1019 are issued for evaluating the effective openings of testing sieves in the

size range U.S. Standard No. 8 through No. 70. These standards are used by placing the entire sample on a clean sieve or on the top of a stack of clean sieves and shaking them in a shaking device or by hand. Each of the sieve fractions of glass spheres is weighed to the nearest 0.01 gram, and the weight percent retained on each sieve is calculated. The effective opening of each sieve is then determined from the calibration data on the certificate supplied with each sample. The

reproducibility of calibrations made with these standards varies from ±2 to ±5 percent of the nominal width of the

sieve openings. SRM 1003 is furnished to calibrate equipment used to determine particle sizes in the 5 to 30 micron range. A certificate

U.S. DEPARTMENT OF COMMERCE—NATIONAL BUREAU OF STANDARDS

INSTITUTE FOR MATERIALS RESEARCH

OFFICE OF STANDARD REFERENCE MATERIALS

GUIDE FOR THE SUBMISSION OF REQUESTS

FOR THE DEVELOPMENT OF NEW OR

RENEWAL STANDARD REFERENCE MATERIALS

August 20, 1964

Introduction The National Bureau of Standards presently has available more than 500 standard reference materials. It

is also working on the development of about 50 new ones and has on hand requests for the preparation of many others. The requests have always far exceeded the Bureau's capacity to produce and certify these materials. Policy One of the main functions of the NBS Institute for Materials Research is to develop, produce, and dis- tribute standard reference materials which provide a basis for comparison of measurements on materials and

aid in the control of production processes in industry. To help carry out thi - function the Office of Standard

Reference Materials evaluates the requirements of science and industry for carefully characterized reference

materials, and directs their production and distribution. Emphasis is given to providing NBS Standard Refer- ence Materials (a) where attainment of needed accuracy of analysis or accuracy of measurement of characteristics is not economically or technically feasible elsewhere, and where such accuracy is generally important to

users, (b) where industry-wide standards for commerce are needed from a neutral supplier who is not otherwise

available, and (c) where continuing availability of highly characterized material from a common source is important to science or industry. The National Bureau of Standards recognizes the need for broadening the present program on reference

materials to include all types of well-characterized materials that can be used to calibrate a measurement system

or to produce scientific data that can be readily referred to a common base. With this broadening, however, it

still remains apparent that the demand for new Standard Reference Materials will continue to far exceed the Bureau's capacity for development. Therefore, requests for new Standard Reference Materials which will have

limited use and for which the need is not very great will have to be passed by in favor of requests clearly showing a critical need. For the purpose of determining which requests are to receive top priority, the National Bureau of Standards will need, and will rely heavily upon, the information supplied by industry, either through

its own representatives or through interested committees, such as those of the American Society for Testing and Materials, the American Standards Association, the International Organization for Standardization, etc. Accordingly, while the Bureau welcomes all requests for the development of new Standard Reference

Materials, it will help both the Bureau, and industry as well, if requests are accompanied by such information

as will permit an assessment of the urgency and importance of proposed new reference materials. Information Needed

Those requesting the development of new Standard Reference Materials should supply as much as possible

of the following information:

(1) Short title of Standard Reference Material.

(2) Purpose for which the new standard material is needed.

(3) Reasons why the new standard material is needed.

(4) Special characteristics and/or requirements for the material. Include additional requirements and

reasons, if more than one standard material is necessary for standardization in this area.

(5) Your estimate of the possible present and future (10 year) demand for this new standard in your own

operations and elsewhere.

(6) Whether this standard, or a similar standard, can be produced by, or obtained from, a source other than the National Bureau of Standards. If so, give reasons to justify its preparation by NBS.

(7) Miscellaneous pertinent comments to aid justification for the new standard reference material, such

as: (a) an estimate of the range of application, monetary significance, and scientific and/or technological significance including when feasible estimates of the impact upon industrial productivity or growth, and (b) supporting letters from industry leaders, trade organizations, interested committees and others.
