Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard was revised based on YY/T 0654-2008. Compared with YY/T
0654-2008, in addition to the editorial modifications, the main technical changes
are as follows.
- modified the applicable scope as automatic biochemical analyzer for
quantitative analysis of various samples by ultraviolet-visible
spectrophotometry;
- in normative references, modified GB/T 14710 “The environmental
requirements and test methods for medical electrical equipment” to GB/T
14710 “Medical electrical environment requirements and test methods.’
- deleted GB/T 2829 “Sampling procedures and tables for periodic inspection
by attributes (Apply to inspection of process stability)” from normative
references;
- deleted YY 0466 “Medical devices - Symbols to be used with medical device
labels labelling and information to be supplied” (ISO 15233.2000, IDT)
from normative references;
- modified the sample carryover rate as not exceeding 0.1% and modified its
test methods (see 5.8, 6.7);
- adjusted the UREA (urea) test range in the intra-assay precision of clinical
projects to 7.0 mmol/L ~ 11.0 mmol/L (see 5.10);
- added the requirements and test methods for applicable provisions of GB
4793.9 and YY 0648 in safety requirements (see 5.13, 6.12);
- added GB/T 18268.1, GB/T 18268.26 electromagnetic compatibility
requirements and test methods (see 5.14, 6.13);
- in the absorbance stability test method, the potassium dichromate solution
used at a wavelength of 340 nm was changed to a yellow orange G
solution (see 6.4);
- in the absorbance repeatability test method, the potassium dichromate
solution used at a wavelength of 340 nm was changed to a yellow orange
G solution (see 6.5);
- the accuracy and repeatability of the test method is modified by the
manufacturer to choose one of two methods (see 6.8);
