Precision and Bias Included, in addition d415 the original data of Test Method E — 71, are data from cooperative testing of a broader xstm of reference materials to expand the element concentration ranges.
The mass fraction ranges of the elements listed have been established through cooperative testing 2 of reference materials. Remember me for one month.
Aatm, it is not required for all applications of this standard. If within the potential range the tube is either too sensitive or too insensitive for the element concentration range, select another photomultiplier. H Resistance, V Peak voltage, V residual 2. Nominal values found to be adequate are listed as follows: The specimen surface should be kept clean because the specimen is the electron emitter, and electron emission is inhibited by oily, dirty surfaces.
Use either a 3, 4, or 5-mm It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. However, if boron nitride disks are used to mechanically restrict the excited area of the sample, a properly excited specimen may not exhibit a dark ring.
However, it is not required for all applications of this standard. The following mold types have been found to produce acceptable samples: NOTE 4—A black deposit builds up on the tip of the electrode, thus reducing the overall intensity of the spectral radiation. This shall be done initially and as often as necessary thereafter to maintain proper alignment.

Excitation and Exposure The specimen thickness can vary significantly according to the design of the spectrometer stand, but a thickness between 10 mm and 38 mm has been found to be most practical.
The specimen thickness can vary significantly according to the design of the spectrometer stand, but a thickness between 10 mm and 38 mm has been found to be most practical. Condition a fresh counter electrode with two to six excitations using the operating conditions in accordance with If readings are not in conformance, repeat the standardization.
Reagents and Materials 7. Automatic sequencing shall be provided to actuate the?
Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. Link to Active This link will always route to the current Active version of the standard. With that equipment, a smooth, white, texture burn without the characteristic dark ring indicates an improperly excited specimen.
The specimen thickness should be between 10 and 38 mm. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.
Center the analytical gap on the optical axes of the spectrometer. The number of acceptable excitations on an electrode varies from one instrument to another, and should be established in each laboratory.
Each laboratory should establish a suitable check procedure. NOTE 10—When parameter values are established, maintain them carefully. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

Using the averages of the data for each point, determine analytical curves as directed in Practices E and E The wall thickness of the mold is approximately 32 mm 11?
