ANNOUNCEMENTS

U.S. announcements which follow concern notification of changes in services and information about future NBS Measurement Seminars.

Specific technical questions regarding the services described in DEPARTMENT these announcements should be referred to the points of contact

indicated. General policy questions regarding NBS measu'^ement services should be referred to the Office of Measurement Services at Qp the address above.

It should be recognized that in many cases where NBS calibration

OOMMEROE services are no longer advertised in SP 250, special arrangements can usually still be made on a case-by-case basis (NBS workload permitting)

if it can be shown that there is a critical need for an NBS calibration.

1. CLASSIFICATION OF NBS SERVICES (W&B)

NBS has recently imposed new Bureau-wide quality control requirements for all services described in this Appendix (this excludes Other NBS Services listed in Section 9.0). The NBS services listed in this Appendix will henceforth be categorized as Calibrations, Measurement Assurance Programs, or Special Tests. Calibration and Measurement Assurance Program services are identified by a H following

the SP 250 number. All other services listed are Special Tests. Details on the meaning attached to these distinctions can be obtained from the technical points of contact in the Appendix. Additional

information will be published in the next Edition of SP 250 which should be available in the Fall of

1982.

2. REDUCTION OF LITTLE USED SERVICES (W)

Several advertised services for which there is little or no demand have been removed from this

Appendix. However, they may be available as a special test if needed. For futher information please

refer to the points of contact listed. The items which were removed are:

1.3N Haemacytometers

Contact: W. Haight, Dimensional Calibrations, 301-921-2216.

3.2X Measurement assurance programs for dc voltage ratio, phase I (Transport ratio standard)

3.2Y Measurement assurance programs for dc voltage ratio, phase II (Transport measuring circuit)

Contact: N. Belecki, Electrical Measurements and Standards Division,

301-921-2715.

8.3H Correction factor for an electrometer and one associated cavity

ionization chamber, one beam quality

8.31 Correction factor for an electrometer and one associated cavity

ionization chamber, each additional beam quality

NOTE: Although these services will no longer be listed as separate items

they will continue to be provided under 8.3B and C. Contact: R. Loevinger, Dosimetry Group, 301-921-2364.

3. LENGTH CALIBRATION SERVICES (ITEM 1.3) (W)

Due to the lack of demand the following calibration services will be eliminated by January 1, 1983:

1.3B Thermal expansion of length standards

1.3D Gage block thermal expansion

1.3E Gage block comparator stulus tip radius

For further information contact: W. C. Haight, 301-921-2216.

4. CHANGE IN DESIGNATION FOR NEAR AND VACUUM ULTRAVIOLET (ITEMS 7.6-7.7) (W)

RADIOMETRIC STANDARDS, BASIC PHOTOMETRIC CALIBRATIONS AND

RADIOMETRIC AND PHOTOMETRIC GAGE CALIBRATIONS

Due to administrative changes at NBS items listed under 7.5, 7.6 and 7.7 have been relabeled. This

has changed our numbering system as follows:

OLD SP 250 NUMBERS NEW SP 250 NUMBERS

7.5 S-Z 7.6 A-D

7.6 A-M 7.7 A-M

7.7 B-F 7.7 N-R

5. BETA-PARTICLE EMITTING SAMPLES (ITEMS 8. 2P-R) (W)

Due to the small demand for these services, beta-particle solution calibrations will not be offered

as routine tests after December 1983.

NBS MEASUREMENT SEMINARS

Seminars and workshops on the topics listed below have been announced for the 1983 series of NBS Measurement Seminars.

The seminars and workshops are NBS activities that provide advice and assistance on measurement and

calibration so that laboratories outside NBS can make measurements consistent with national standards

as maintained by NBS. Participation is open to a limited number of persons from measurement and

standards laboratories who meet appropriate prerequisites relating to education, work experience, and current professional activity.

Microwave Antenna Measurements

Accurate means of measurement of antenna gain, pattern, and polarization are generally available

from about 500 MHz to about 75 GHz. However, measurements of all three characteristics may not

be practical for a given antenna because the measurement accuracy, capability, and cost depend

on the frequency, type and size of antenna, and the parameters to be measured. Therefore, a particular measurement must be negotiated in advance. The following methods and facilities

are used for these measurements.

( 1 ) PI anar Near Field Scanni ng Method

With this technique, gain, pattern and polarization parameters are calculated from

near-field amplitude and phase measurements taken over a plane area close to the test

antenna. The absolute gain can be determined to within ±0.15 dB, polarization axial

ratio to within about ±0.10 dB/dB and side lobe levels can be obtained down to -50 or -60 dB. (The exact uncertainties will depend on the frequency, type, and size of antenna, etc.) Antennas with apertures up to about 3.5 m in diameter can be managed. Measurements can be made from 750 MHz up to 75 GHz, with best results achieved above

1 GHz.

(2)11 Extrapol ati on Range Measurements

In this method, the received signal transmitted between a pair of antennas is measured as

a function of the separation distance between the antennas. The antennas need not be identical, and no assumptions concerning the polarization are required. The method is not well suited for pattern measurements, but it is the most accurate technique known for absolute gain and polarization measurements. Above 1 GHz, the accuracies are typically

±0.08-0.10 dB for gain measurements, and ±0.05 dB/dB for polarization axial ratio measurements. There are uppersize limitations associated with existing NBS extrapolation

ranges. These limitations depend on the type of antenna, the frequency, and the desired measurements and accuracies. Therefore, negotiations must be conducted prior to submitting antennas for calibration to ascertain if all requirements can be met.

4.3 IMPEDANCE OR ADMITTANCE

(Capacitance, inductance, resistance, conductance, Q, dissipation factor impedance magnitude,

phase angle. Voltage Standing Wave Ratio (VSWR), reflection coefficient, return loss). Items 4.3A, B and C utilize lumped parameter measurement techniques such as bridges, LCR Meters and resonance methods over the frequency range from 30 kHz to 250 MHz. Item 4.3F utilizes the distributed parameter measurement approach employing an automatic network analyzer (ANA) over the frequency range 0.1 to 18 GHz. In the range from 0.1 to 0.25 GHz where there is overlap between lumped and distributed parameter capabilities, NBS will choose the best

method for the item to be calibrated. Items 4.3G and 4.3H pertain to rectangular waveguide

items.

NBS Special Publication 260, "Standard Reference Materials," lists and describes the Standard

Reference Materials (SRM's), Research Materials (RM's), and General Materials (GM's) currently

distributed by the National Bureau of Standards, as well as many of the materials currently in preparation. SRM's are used to calibrate measurement systems and to provide a central basis

for uniformity and accuracy of measurement. The unit and quantity, the type, and the certified

characterization are listed for each SRM, as well as directions for ordering. The RM's are issued to meet the needs of scientists engaged in materials research and are issued with a "Report of Investigation." The GM's are standardized by some agency other than NBS. NBS acts only as a distribution point and does not participate in the standardization of these materials. Announcements of new products are made by mail to those who have requested such information

The research and testing facilities for structural engineering include a 53-MN (12 million-lbf)

capacity universal testing machine believed to be the largest in the world. A significant

addition to the nation's facilities for research and testing in the field of large structures,

this unique machine is available to do work for the entire technological community upon consideration of requests on a case-by-case basis. This hydraul ical ly operated machine is a vertical, four screw type with the main fixed platen flush with the floor. It is capable of applying 53 MN (12 x 10^ Ibf) in compression to test speciments up to 17 m (58 ft) in height and

27 MN (6 X 10® Ibf) in tension to speciments up to 16 m (53 ft) in length. To extend the versatility of the machines, the reinforced concrete foundation incorporates a floor tie-down

system which can accommodate test specimens for transverse loading up to 27 m (90 ft) in length.

Calibration of all load ranges indicates that they exhibit error generally no greater than 0.5 percent of the applied load. A more detailed description of this facility is presented in NBS Special Publications 355.
