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 standard 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 information and we hope will stimulate the use of standard reference materials in science and industry.

Standard Reference Materials

Issued by the National Bureau of Standards

A descriptive listing is given of the many different Standard Reference Materials issued by

the National Bureau of Standards to calibrate a measurement system, or to produce scientific data that can be referred to a common base. A schedule of prices and amounts, as well as directions

for ordering, is included. For composition standards summary tables of analyses are presented,

to indicate the type of standards presently available. Announcements of new standard reference materials will be made in the Federal Register, in scientific and trade journals, and in the Technical News Bulletin of the National Bureau of Standards. The current status of the various standards will be indicated by an insert sheet available quarterly from the Bureau.

1. General Information

1.1. Introduction

This publication lists the standard reference

materials issued by the National Bureau of Standards, their prices and directions for ordering.

The NBS Standard Reference Materials Program

provides all types of well-characterized materials

that are needed to calibrate a measurement system or to produce scientific data that can be readily re- ferred to a common base. Some of the principal uses of NBS standard

reference materials are : Calibrating and standardizing spectrometers, spectrographs, colorimeters, pH

meters, Geiger counters, scintillators, ionization

chambers, pyrometers, polarimeters, refractometers,

viscometers, and other laboratory and plant instruments; checking methods of analysis and analytical

techniques; standardizing solutions for volumetric

analysis; developing new or improved methods of analysis and evaluating 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 ex- tended 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 certi- fication of composition or properties. More recently,

the term "Standard Sample" has been replaced with

the more apt description "Standard Reference

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 500 different standards

of metals, ores, ceramics, chemicals, and hydrocarbons are now available for distribution. About

380 of these are certified for chemical composition.

Some 177 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

example 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 be- comes 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.

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 Quarterly

insert sheet for this catalog 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.

1
The Office of Standard Reference Materials wel- comes 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 Reference Materials" which delineates

Bureau policy 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 instrument* are given in a separate publication; NBS Miao. Publ. 260, Calibrating and Testing Services, price 70 cents.

2. Purchase Procedure

2.1. Identification of Standards

The standards are listed by groups; the numbers

represent the issuance of the first representative

sample of each kind. Renewals are indicated 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. 11 Basic

Open-Hearth Steel, 0.2 percent carbon. In this way, a particular number always represents a

material of fixed or approximately fixed composition.

(providing that the parcel does not exceed the

weight limits as prescribed by Postal Laws and

Regulations) unless the purchaser 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.

2.2. 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, number and name of the standards

requested. For example: 150 grams of No. llg

Basic Open-Hearth Steel, 0.2 percent C. The fist 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.

2.3. Terms and Shipping

2.3.1. Domestic Shipments

Shipments of material (other than hydrocarbons,

organic sulfur compounds and radioactive standards)

intended for the United States, Mexico, and

Canada are normally shipped prepaid parcel post

2.3.2. Foreign Shipments

Small shipments will be forwarded as a United

States Government shipment via International

Parcel Post, providing that the parcel does not

exceed the weight limits as prescribed by Postal

Laws and Regulations 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 United States 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 United States

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 alleys 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 certification 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 Vn inch in diameter, 4 inches long (400

series); (2) rods /l 2 inch in diameter, 2 inches long (800 series); and (3) disks 1 1£ inches in diameter and either % inch or inch

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 1100 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 a certificate of analysis which gives 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.)

Carbon Steels (Certified for Oxygen and Nitrogen Only)

This group of standards is intended to provide material of known composition for checking analytical methods for the de- termination of oxygen and nitrogen only. The materials are supplied in rods one inch in diameter and three inches long. Because some of these materials are radially segregated, care must be taken so that the sample used for the analysis represents the entire cross section of the bar.

3.3. Cast Iron (Chip Form)

This group of standard reference materials is similar to the steels described in 3.1 and has been prepared for use in checking chemical methods in the cast iron industry. These materials, except White Iron No. 3a, are furnished as 150 g portions in the form of chips, usually sized between 16- and 25-mesh sieves. They are prepared from thin-wall cylindrical castings specially made

for this purpose by lathe cutting the chips with a multiple-tooth cutting tool. Supplied with each material is a Certificate of Analyses listing the composition as determined at the National Bureau of Standards and by outside laboratories.

3.4. White Cast Iron (Solid Form)

This group of white cast iron standards has been prepared for the cast iron industry to meet the urgent needs for analytical control by rapid instrumental methods. Although they are often employed in x-ray spectroscopic analysis, these standards are

also particularly useful for the primary calibration of vacuum optical emission spectrometers in that they permit the determination

of carbon, phosphorus, and sulfur in addition to the other metallic elements. These materials are furnished as chill-cast sections approximately \}4, inches square and % inch thick. Details of the preparation and intended use of the standards will be found in the National Bureau of Standards Misc. Publ. 260-1, Preparation

of NBS White Cast Iron Spectrochemical Standards by R. E. Michaelis and LeRoy L. Wymau (1964). The standards are fur- nished with a provisional certificate of analyses.

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

3.7. Copper-Base Alloys (Solid Form)

Several groups of copper-base alloy standards have been prepared to provide for analytical control by rapid instrumental 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. The materials are furnished iu two basic forms: (1) unidirectional chill-cast samples (CllOO series) in the form of solid sections l\i inches square, % inch thick, and (2) wrought material (either forged or hot-extruded) in the form of disks 1J4 inches

in diameter, ^ inch thick (1100 series). Details on the preparation and use of the materials can be found in National Bureau of Standards Misc. Publ. 260-2, Preparation of NBS Copper-Base Spectrochemical Standards by R. E. Michaelis, LeRoy L. Wyman,

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

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

These standards, widely used in the automotive industry, 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 % inches square and % inch thick. They were prepared by a continuous chill-casting process. The certified portion of each standard is that part included between %, inch and % inch from each side of the square sample. The center core, % inch square; and the

outer portion, %8 inch 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 composition as determined at the National Bureau of Standards,

and all except the spelter include values obtained 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.)

4.6. Standard Rubbers and Rubber Compounding Materials

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 ac- cordance 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. .

Also these polymeric samples can be used for determining the feasibility of some fractionating techniques since the ratios of the Mn , Mw, and z-average molecular weight are also given. The intrinsic viscosities at a high rate of sheer both in benzene and cyclohexane are also stated. In addition, these samples represent highly purified polystyrene samples for polymeric research requiring the following chemical characteristics: Standard 705 has a relatively narrow molecular weight distribution with a Mw 1.8 X 106

. The sample was prepared by the polymerization of styrene in benzene using butyl lithium as an initiator. Ash content and volatiles are 0.05 and 0.5 percent, re- spectively. The polystyrene is in pellet form, each pellet weighing about 10 mg. Standard 706 has a reasonably broad molecular weight distribution, the ratio Mw/M„ being 2.1, and an Mw of 2.7 X 10'. The sample was prepared by the thermal polymerization of styrene at 140 °C to 37 percent conversion. Ash content and volatile content are 0.001 percent and 0.8 percent respectively. The polystyrene is in pellet form, each pellet weighing about 80 mg.

4.8. Viscometer Calibrating Liquids

These oils are not intended for use as permanent viscosity standards, are not suitable for stockroom items, and should be

ordered only for immediate use. They are available only in containers of normal 1-pint capacity, as this quantity is sufficient for the calibration of most viscometers. In cases where a larger quantity (duplicate sample) is required, a nominal explanation of the need for the larger quantity must be given in the order or an accompanying letter. All available liquids are hydrocarbons

and are listed below. Because of the nature of the materials, all samples will be shipped by railway express, express charges collect

.

4.8.1. CGS Units

Oils for use with viscometers calibrated in CGS units are supplied with a report containing values for viscosity, kinematic

viscosity and density at the listed temperatures. Viscosity values at other temperatures in the range of 20 to 100 °C (30 to 100 °C

for oil P) are supplied as a special service. For oils D through N, the charge for this special service is $15.00 per sample per temperature. For oils OB and P, the charge is $32.00 per sample per temperature. These special service charges are in addition

to the charge for the sample and usual report. Further details on the composition and properties of these oils, a description of the procedure used in their calibration, and

a discussion of their use in the calibration of capillary viscometers, is given in NBS Monograph 55, "NBS Viscometer Calibrating

Liquids and Capillary Tube Viscometers" by R. C. Hardy (1962).

4.10. Color Standards for Spectrophotometer-Tristimulus 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 tri- stimulus 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 speetrophotometer-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.

4.18. Glass Spheres for Sieve Calibration

These standards are issued for evaluating the effective openings of testing sieves in the size range U.S. Standard No. 8 through No. 270. 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 cali- bration 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.

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 distribute 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 this 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 Reference 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 develop- ment. 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 de- termining 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 sig- nificance including when feasible estimates of the impact upon industrial productivity or growth, and (b) sup- porting letters from industry leaders, trade organizations, interested committees and others.
