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, this 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

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 Reference 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. 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. 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 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.

2.3.2. 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 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 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 'or 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 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 %2 in in diameter, 4 in long (400 series)

(2) rods Yi 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 % in in diameter and 1091 is Y\t 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.)

3.7. 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 (C1100 series) in the form of

solid sections l}i in sq, in thick, and (2) wrought material (either forged or hot-extruded) in the form of disks l}i 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 % in thick; and others in chill-cast form (1190, 1204, and 1205) as sections 1% inches sq. and % in thick. (Values in parentheses are not certified, but are given for additional information on the composition.) 8RM

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 Ms in and in from each side of the square sample. The center core, in square; and the outer portion, M« 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.

3.17. Hydrocarbon Blends

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.

4.6. Standard Rubbers and Robber 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 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.

4.7. Polystyrene Molecular Weight Standards Two samples of polystyrene are available for use in calibrating non-absolute techniques of measuring the numberaverage (M„) and weight-average (Af„) molecular weights. Also these polymeric samples can be used for determining the

feasibility of some fractionating techniques since the ratios of the M„ Af„, and z-average molecular weight are also given. The intrinsic viscosities at a high rate of shear 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 M9 1.8X10*. The sample was prepared by the polymerization of styrene in benzene using butyl lithium as an intiator. Ash content and volatiles are 0.05 and

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 ancfiero 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. SRM Nos. 2101 2102 2103 2104

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) Shore 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.

PUBLICATION 260-STANDARD REFERENCE MATERIALS

Catalog and Price List of Standard Materials Issued by the National Bureau of Standards New and renewal Standard Reference Materials continuously are being prepared while the supply of others may be exhausted. This Quarterly Addendum is issued to bring the Catalog and

Price List up-to-date as of February 1, 1968. CHANGES IN PURCHASE PROCEDURE

2.3. Terms and Shipping

2.3.1. Domestic Shipments

Shipments of material (other than hydrocarbons, organic sulfur compounds, and radioactive standards) in- tended for the United States, Mexico, and Canada are normally shipped prepaid parcel post (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, and radioactive standards are shipped express collect. No discounts are given on NBS Standard Reference Materials. Shipment will be made from Washington, D. C, approximately two weeks after receipt of your purchase

order. Prices as quoted are subject to change without notice. Prices in effect at time of shipment will be billed to the purchaser, and invoice will follow shipment.

2.3.3. Payment for Foreign Orders The National Bureau of Standards does not reserve materials. Therefore, your order will be subject to adjustment of the numbers of each item ordered depending upon inventory levels upon receipt of your payment.

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 stand- ard rate of U. S. currency. Prices as quoted are subject to change without notice. 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 radioactive standards) in- tended for the United States, Mexico, and Canada are normally shipped prepaid parcel post (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, and radioactive standards are shipped express collect. No discounts are given on NBS Standard Reference Materials. Shipment will be made from Washington, D. C, approximately two weeks after receipt of your purchase

order. Prices as quoted are subject to change without notice. Prices in effect at time of shipment will be billed to the purchaser, and invoice will follow shipment.

2.3.3. Payment for Foreign Orders The National Bureau of Standards does not reserve materials. Therefore, your order will be subject to adjustment of the numbers of each item ordered depending upon inventory levels upon receipt of your payment.

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 stand- ard rate of U.S. currency. Prices as quoted are subject to change without notice. Prices in effect at time of shipment will be billed to the purchaser.

U.S. DEPARTMENT OF COMMERCE

NATIONAL BUREAU OF STANDARDS November 1, 1968

QUARTERLY INSERT SHEETS FOR NBS MISCELLANEOUS

PUBLICATION 260-STANDARD REFERENCE MATERIALS

Catalog and Price List of Standard Materials Issued by the National Bureau of Standards New and renewal Standard Reference Materials continuously are being prepared while the supply of others may be exhausted. This Quarterly Addendum is issued to bring the Catalog and

Price List up-to-date as of November 1, 1968.

1. General Information (ADDITIONAL)

1.4. Standard Reference Materials (SRMs) Transferred to Other Organizations

Under certain circumstances it is more practical for the National Bureau of Standards to transfer the custody and responsibility for the sale and distribution of a particular group of SRMs. Notification of such a transfer

will normally be given under the appropriate section of this catalog. In one case, however, this was not done due

to the reorganization of this catalog.

Hydrocarbon Blends

Standard samples of hydrocarbons of certified purity which were prepared by NBS in cooperation with the American Petroleum Institute are now available only as API Standard Samples from: API Samples

Attn: A. J. Streiff Carnegie-Mellon University Schenley Park

Pittsburgh, Pennsylvania 15213

Telephone: AC 412 621-2600 Ext. 531 Complete information concerning these standards may be obtained from the API Samples office.
CHANGES IN PURCHASE PROCEDURE

2.3. Terms and Shipping

2.3.1. Domestic Shipments

Shipments of material (other than hydrocarbons, organic sulfur compounds, and radioactive standards) in- tended for the United States, Mexico, and Canada are normally shipped prepaid parcel post (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, and radioactive standards are shipped express collect. No discounts are given on NBS Standard Reference Materials. Shipment will be made from Washington, D. C, approximately two weeks after receipt of your purchase

order. Prices as quoted are subject to change without notice. Prices in effect at time of shipment will be billed to the purchaser, and invoice will follow shipment.

2.3.3. Payment for Foreign Orders The National Bureau of Standards does not reserve materials. Therefore, your order will be subject to adjustment of the numbers of each item ordered depending upon inventory levels upon receipt of your payment.

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 stand- ard rate of U.S. currency. Prices as quoted are subject to change without notice. Prices in effect at time of shipment will be billed to the purchaser.

These chill-cast 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, phoshorus, and sulfur in addition

to the metallic elements. These materials are furnished as chill-cast sections approximately 1% in. sq. and Y2 in. thick. Details of the preparation and intended use of the standards are in the NBS Misc. Publ. 260-1, Preparation of NBS White

3.25. High-Purity Metal Materials (New Standard Reference Materials)

These standards are intended to meet the urgent need of analysts working at trace level concentrations of elements in high-purity metal materials. The standards should serve not only for important benchmarks in calibra- tion of equipment but also for development of new or improved methods and techniques in extending the sensitivity of detection in the determination of trace constituents in various materials by chemical, optical emission and

solids mass spectrochemical, activation, and resistivity methods.

3.25.1. Platinum These standards have been established to provide homogeneous reference materials for the analyses of highpurity platinum. Designated SRM No. 680, High-Purity Platinum and SRM 681, Doped Platinum, the materials are available in wire form, 0.020 inch (0.51 mm) in diameter, and are issued in two lengths, 4 in (10.2 cm) and

39.4 in (1.00 meter), designated L-1 and L-2, respectively. Both standards have been certified for a dozen impurity

elements which in general range from a fraction of a part per million (by weight) in the high-purity platinum

to about 10 in the doped platinum. A Certificate of Analysis supplied with the standards gives the range of values reported which represents the present state of the art in the cooperating laboratories for the various trace determinations. SRM No. Kind Price

3.25.2. Zinc These zinc metal standards have been prepared to provide research materials characterized with respect to trace impurity elements for use primarily in extending analytical methods for trace element determinations. Additionally, the materials are expected to serve in furthering research in physical measurement systems with in- creased correlation between physical and chemical characterization. Designated SRM No. 682, High-Purity Zinc, and SRM No. 683, Zinc Metal, the materials are available in the form of semicircular bar segments about 2%

in in diameter, 1 in deep at mid-diameter, and % in long. The same starting material was used in the preparation of both standards; however, the High-Purity Zinc, SRM 682, was further purified by vapor distillation, zone

refining, and degasification. The total impurity content of SRM No. 683 is estimated to be about 25 ppm (wt) whereas the total impurity content of SRM No. 682 is near 1 ppm (wt). A Certificate of Analysis supplied with the standards gives the recommended values for the elements deter- mined (Ag, Cd, Cu, Fe, and Sn in both standards, and additionally Pb and Tl in SRM No. 683), and estimated upper limits of concentration for all other elements detected as being present by either neutron activation analysis, spark source mass spectrometric analysis, or both.

3.25.3. High-Purity Gold

This standard has been established to provide a homogeneous reference material of high^purity gold. It is issued in two forms, wire and rod. The wire form, designated SRM 685-W, is 1.4 mm (0.055 in) in diameter and

10.2 cm (4 in) long. The rod form, designated SRM 685-R, is 5.9 mm (0.23 in) in diameter and 2.5 cm (1 in) long. The wire form is intended for applications such as spark-source mass spectrometry where the low level of

impurities should make it useful for evaluating instrument and system blanks. The rod form is intended for use

in other methods of characterization and in other scientific applications. A Certificate of Analysis supplied with the standard gives the "state of the art" information on the composition, including values for Cu, In, Fe, O, and Ag, and estimated upper limits of concentration for 21 additional elements which were detected by spark source mass spectrometry.
