Standardization will be done anytime veri? Included, in addition to the original data of Test Method E — 71, are data from cooperative testing of a broader range of reference materials to expand the element concentration ranges.
Natural Salt Spray Testing of various powder coated, painted, galvanized components. Land Use and Development. As the voice of the U.

In general this condition will not affect analytical performance for the? Active view current astm e of standard. Precision and Bias These cover all or part of the concentration ranges listed in 1. The following mold types have been found to produce acceptable samples: NOTE 10—When parameter values are established, maintain them carefully.
NOTE 13—The range of anode to cathode potentials for a given tube should be speci? Other internal standard and analytical lines, such as those listed in Table 2, may be used provided that it can be shown experimentally that equivalent precision and accuracy are obtained.
Repeat with different random sequences at least two times.
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. The specimen thickness should be between 10 and 38 mm.
NOTE 2—Clean the excitation chamber when the counter electrode is replaced. If you feel that your comments asgm not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Note 1The concentration ranges of the elements listed have been established through cooperative testing of reference e41-08. It is assumed that all who use this test method will be analysts capable of performing common laboratory procedures skillfully and safely. The specimen surface should be kept clean because the specimen is the electron emitter, and electron emission is inhibited by oily, dirty surfaces.
Means of changing the? There shall be at least three calibrants for each element, spanning the required concentration range. Excitation and Exposure The discharge is terminated at a predetermined intensity time integral of a selected iron line, or at a predetermined time, and the relative radiant energies or concentrations of the analytical lines are recorded.
E Standard Terminology Relating to Metallography. Work Item s – proposed revisions of this standard.
With a thoriated tungsten electrode, it has been reported that a hundred or more excitations can usually be made before replacement.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. However, it astk not required for all applications of this standard. Each laboratory should establish a suitable check procedure. Salt Spray Testing Equipment Model: A number in parentheses indicates the year of last reapproval. It is assumed that all who use this test method will be analysts capable of performing common laboratory procedures skillfully and safely.
Subscription pricing is determined by: B Quantitative range in accordance with Practice E Digital Torque Wrench Calibrator Model: Proceed to Checkout Continue Shopping. The potentials on the capacitors may be read directly, or a number of different readout systems may be employed which asgm linear or logarithmic functions of the potentials and which may be displayed as relative numbers or as numbers calibrated directly in terms of percent.
Calibration, Standardization, and Veri? Use either a 3, 4, or 5-mm Today, some 12, ASTM standards are used around the world to improve astm e quality, enhance safety, facilitate market access and trade, and astm e consumer confidence.
Notch broaching with 25HRC Application: NOTE 4—A black deposit builds up on the tip of the electrode, thus reducing the overall intensity of the spectral radiation. Clean the lens or protective window after approximately to excitations to minimize axtm losses.
Load Capacity KN Max. Need more than one copy? Enter your account email address to request a password reset: Condition a fresh counter electrode with two to six excitations using the operating conditions in accordance with Periodic calibration of static type Torque wrenches. Secondary slit width is 50 to ? The number of acceptable excitations on an electrode varies from one instrument to another, and should be established in each laboratory.
