Equipment varies among laboratories. Silver or thoriated tungsten rods are typically used. Current edition approved March 1, Procedure for Excitation and Radiation Measurement Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
A verifier may be used as a calibrant even though it is burned only as a verifier.
Originally approved in Position the specimen so there will be a uniform pattern of excitations around its face. A variety of such systems are commonly used.
Preparation of Samples 9. These reference materials shall be homogeneous, and free of voids or porosity. Excitation and Integration Examine the specimen after each excitation to evaluate the quality of excitation. The radiant energy of selected analytical lines are converted into electrical energies by photomultiplier tubes and stored on capacitors.
Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable.
ASTM International – Standard References for ASTM E – 14
A minimum of three reference materials shall be used for each element. Counter electrodes and argon are described in 7. Typically, every 4 h to 8 h is practical and adequate or if the instrument has been idle for more than 1 hour. The resulting surface should be uniformly plane and free of defects. Repeat standardization as necessary so verifications are within control limits or investigate further for instrument problems. E1806 may be either wet or dry grinding devices.
The samples e108 be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials.
Make a e0186 electrical ground. The discharge is terminated at a predetermined level of accumulated radiant energy from the internal standard iron line or after a fixed integration time.
ASTM E1086 – 14
Automatic sequencing shall be provided to actuate the flow at a given rate for a specific time interval. We are a non-profit group that run this website to share documents. These data were obtained by procedures outlined in Practice E Referenced Documents purchase separately The documents astj below are referenced within the subject standard but are not provided as part of the standard. Flush, s Preburn, s Integration, s 2 10 10 or 15 Argon Flow 0.
Link to Active This link will always route to ast, current Active version of the standard. The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials.
Other material may be used provided asstm can be shown experimentally that equivalent precision and accuracy are obtained. Please fill this form, we will try to respond as soon as possible. The flow rate may be manually or automatically controlled. The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials.
