Foreword
GB/T 14233 "Test methods for infusion, transfusion, injection equipments for medical use"
is divided into two parts.
— Part 1. Chemical analysis methods;
— Part 2. Biological test methods.
This Part is Part 1 of GB/T 14233.
This Part replaces GB/T 14233.1-1998 "Test methods for infusion, transfusion, injection
equipments for medical use-Part 1. Chemical analysis methods". In considering that the
GB/T 14233.1-1998 has been widely cited by many product standards, in order to avoid
the confusion due to changes of the clause numbers, the clause numbers in this Part are
kept as unchanged as possible to the corresponding clause numbers in the previous
version. Therefore, the contents which need to be modified are revised under the previous
clause numbers. For newly-added contents, new clause numbers and methods are added
on top of previous clause numbers.
Compared with GB/T 14233.1-1998, this Part has the following major changes.
— MODIFY solution preparation and expression methods;
— ADD preparation methods of test solutions - for products such as irregular products
with short service time (shorter than 24 hours) and larger volume, irregular-shape
products with longer service time (longer than 24 hours), and water absorbing
materials;
— ADD turbidity and luster test methods;
— MODIFY test methods for chloride, pH value, heavy metal, ammonium, zinc, ignition
residue, ethylene oxide residue content;
— ADD atomic fluorescence spectroscopy test method;
— DELETE sulphate test method.
This Part was proposed by the State Food and Drug Administration.
This Part is under the jurisdiction of National Technical Committee on Medical Syringes of
Standardization Administration of China.
Drafting organization of this Part. Jinan Quality Supervision and Inspection Center for
Medical Devices.
Chief drafting staffs of this Part. Luo Hongyu, Pan Huaxian, Shi Yanping, Sun Guangyu, Li
Kefang, Qin Dongli, Liu Bin, Liu Lili, and Guo Lun.
The previous standard replaced by this Part are.
- GB/T 14233.1-1993;
- GB/T 14233.1-1998.
Test Methods for Infusion, Transfusion, Injection Equipments
for Medical Use - Part 1. Chemical Analysis Methods
1 Scope
This Part of GB/T 14233 specifies the chemical analysis methods for infusion, transfusion,
injection equipments for medical use.
This Part is applicable to the chemical analysis for infusion, transfusion, injection and
supporting equipments for medical use made of medical macromolecular materials. The
chemical analysis for other medical macromolecular products may also adopt this Part for
reference.
2 Normative references
The articles contained in the following documents have become part of this Part when
they are quoted herein. For the dated documents so quoted, all the modifications
(excluding corrections) or revisions made thereafter shall not be applicable to this Part.
For the undated documents so quoted, the latest editions shall be applicable to this Part.
GB/T 601 Chemical reagent - Preparations of Standard volumetric solutions
GB/T 6682 Water for Analytical Laboratory Use - Specification and Test Methods (GB/T
6682-2008, ISO 3696.1987, MOD)
Pharmacopoeia of People's Republic of China (2005 Edition) Volume II
3 General Rules
3.1 All analysis in this Part shall be carried out and based on 2 parallel test groups. The
test results shall be within the allowable relative deviation limits. Arithmetic mean shall be
adopted as the test result. If one result is qualified and the other one is unqualified, the
results shall not be averaged. And tests shall be re-performed.
3.2 Unless otherwise specified, all reagents used in this Part are analytical pure.
3.3 Unless otherwise specified, all test water in this Part shall meet the requirements of
Class II water in GB/T 6682.
3.4 Term "room temperature" in this Part refers to 10 ºC ~ 30 ºC.
3.5 Term "accurate weighing" in this Part refers to weighing to the accuracy of 0.1mg.
3.6 Term "accurate measuring" in this Part refers to measure with pipette meeting the
requirements of the accuracy specified by corresponding national standards.
3.7 Gravimetric method constant weight refers to that the mass difference of test
substance between 2 consecutive flamings or dryings shall not exceed 0.3mg.
3.8 Unless otherwise specified, all glass vessels used in this Part are borate glass
containers.
4 Preparation of Test Solution
4.1 During the preparation of test solution, it shall simulate as possible the conditions
endured during the product usage process (such as the application area, time and
temperature of the product). Simulated leaching time shall not be shorter than the product
normal usage time. Where the service time of products is relative long (longer than 24
hours), test solution shall be prepared in consideration of accelerated test conditions,
however, the feasibility and rationality shall be verified.
4.2 Methods used for preparing test solution shall meet as possible that all tested surfaces
of samples SHOULD be extracted.
4.3 It is recommended to choose the preparation method of test solution from Table 1.
iodide. Dissolve it in 10mL water. Slowly add saturated water solution of mercury
bichloride and stir at the same time until generating red precipitation and without
dissolution. Add and dissolve 30g of potassium hydroxide. Add 1mL or more saturated
water solution of mercury bichloride. Dilute it to 200mL with adequate amount of water.
Lay it aside to precipitate. Take the supernatant liquor for use. Inspection. Take 2mL of the
above-prepared solution. And after adding 50mL of water with 0.05mg ammonia, the
solution shall present yellow-brown color immediately.
Ammonium standard stock solution (0.1 mg/mL). Weigh 0.297g of ammonium chloride.
Dry to constant weight at 105ºC~110 ºC. Dissolve it in water and dilute to 1000mL.
Ammonium standard solution. Accurately measure ammonium standard stock solution
before use. And dilute it to the required concentration.
5.8.3 Test procedure
Accurately measure 10mL of test solution. Pour it into a 25mL Nessler tube. Take another
25mL Nessler tube. Add 10mL of ammonium standard solution. Respectively add 2mL of
sodium hydroxide solution (40g/L) into above-mentioned two tubes to make the solution
alkaline. Dilute the solution to 15mL with distilled water. And then add 0.3mL of Nessler
reagent.
Inspect the solutions after 30s. Compare the colors of test solution and control solution.
5.9 Some heavy metal elements
5.9.1 Atomic absorption spectrophotometer method
5.9.1.1 Instrument
Atomic absorption spectrophotometer shall be operated according to the instrument’s
instructions when using.
5.9.1.2 Analysis method (standard curve method)
Within the recommended concentration range of instrument, prepare at least five standard
solutions of which the concentrations are incremented in sequence and which contain the
elements to-be-determined. Use the solvent which is used in standard solution
preparation to adjust the absorbance to zero. Determine the absorbance of each standard
solution. And draw the standard curve of absorbance to concentration.
Atomic fluorescence spectrophotometer shall be operated according to the instrument’s
instructions when using.
7.3.3 Analysis Method
Within the recommended concentration range by instrument, prepare at least five
standard solutions (containing to-be-determined elements) of which the concentrations
are incremented in sequence. Use the solvent which is used to prepare standard solution
to zero-set the absorbance. And then measure the absorbance of each standard solution
in turn. And make the standard curve relative to the concentration.
Measure the test solution prepared and blank control solution. Find out the corresponding
concentration on the standard curve according to absorbance. Calculate the content of
elements...
