Masks shall be provided in the spectrometer to eliminate scattered radiation.

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. The ring is placed on a? It is designed for chill-cast, rolled, and forged specimens. This shall be done initially and as often as necessary thereafter to maintain proper alignment. Precision and Bias Each laboratory aatm establish a suitable check procedure.

ASTM-E, –

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. 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. There shall be at least three calibrants for each element, spanning the required concentration range. It is expected that work will be performed in a properly equipped laboratory.

Automatic sequencing shall be provided to actuate the? Better performance is expected when reference materials and specimens are of similar metallurgical condition and composition.

With a thoriated tungsten electrode, it has been reported that a hundred or more excitations can usually e145 made before replacement. Land Use and Development. It is not within the scope of an ASTM test method to prescribe the minute details of the apparatus preparation which may differ not only for each manufacturer, but also for different equipment from the same manufacturer.

Search book title Enter keywords d415 book title search. NOTE 3—A pump with a displacement of at least 0. With that equipment, a smooth, white, texture burn without the characteristic dark ring indicates an e145 excited specimen.

However, because of differences between these CRMs and the production specimens prepared by the sampling procedures recommended for this test method, curves based on CRMs may in very unusual circumstances need to be corrected with values from reference materials made by normal production sampling techniques and analyzed in accordance with Test Methods E 30, Eand E The specimen thickness can vary significantly according to the design of the spectrometer stand, but a thickness between 10 mm and 38 mm aetm been found to be most practical.

The mass fraction ranges of the elements listed have been established through cooperative testing 2 of reference materials.

Link to Active This link will always route to the current Active version of the standard. Its approximate range shall be from Excitation and Exposure The following mold types satm been found to produce acceptable samples: Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. These cover all or part of the concentration ranges listed in 1.

NOTE 2—Clean the excitation chamber when the counter electrode is replaced.

ASTM E415 – 17

The absorption of the radiation by air in this region is overcome by evacuating the spectrometer and? Cut asym 13 to mm 1? Molecular gas impurities, nitrogen, oxygen, hydrocarbons, or water vapor, either in the gas system or from improperly prepared specimens should be minimized.

Additional data for withinlaboratory variability of results, obtained by analyzing three specimens of one material in seven laboratories in accordance with source conditions speci? This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
