Foreword
Instead of the standard YS/T 559-2006 "Emission Detector tungsten" (formerly GB/T 16600-1996).
Compared with this standard YS/T 559-2006, the following main changes.
--- The "7.1" in "accurately weighed 0.400g sample" to "5.2" in the "Weigh (0.4 ± 0.001) g sample."
--- The "7.2" in the "sample taken (7.1) and 0.200g buffer (4.21) Research uniform" to "5.3" in the "Take sample (5. 2) and
(0.2 ± 0.001) g buffer (3.21) Research uniform. "
--- The "7.3" in the "After adjusting each number separately weighed 0.400g and 0.200g standard buffer (4.21) Research uniform" to "5.4" in the
"After each take, respectively, said after the calibration standard resolution (0.4 ± 0.001) g and (0.2 ± 0.001) g buffer (3.21) Research uniform."
--- Increasing the foreword, precision and quality assurance and control content, and format of the standard editing.
