Foreword
This Standard replaces YY 0242-1996 Polypropylene material for manufacture
of infusion, transfusion and injection equipment for medical use.
Compared with YY 0242-1996, the main changes of this Standard are as
follows.
— ADJUST from mandatory standard to recommended standard.
— ADD the performance requirements of the polypropylene random
copolymer (PP-R) for medical use.
— DIVIDE the PP-H and PP-R materials for medical use INTO the
polypropylene material for manufacture of infusion, transfusion and for
injection equipment.
— REVISE the test item “Cleanliness (color granules and irregular granules)”
to “Granule appearance (color granules)”.
— REVISE the test item “Izod impact strength” to “Notched izod impact
strength”. REVISE the unit from “J/m” to “kJ/m2”. Respectively REVISE
the PP-H index and PP-R index to “≥ 2.0kJ/m2” and “≥ 3.0kJ/m2”.
— For the polypropylene material for manufacture of injection equipment,
REVISE the test item “Transmissivity” to “Haze”. The index is less than
or equal to 15%.
— REVISE the test item “Melt flow rate” to “Melt mass-flow rate”. MODIFY
the index to (0.8-1.2) nominal value (provided by the supplier).
— INCREASE the index of heavy metal content to 1.0μg/mL.
— ADD the “UV absorption rate”.
This Standard was proposed by and shall be under the jurisdiction of the
National Standardization Technical Committee for the Infusion Equipment for
Medical Use (SAC/TC106).

5 Test methods
5.1 Determination of limiting values
Use rounding-off values to determine the test results according to the provisions
specified in the Article 5.2 of GB/T 1250-1989 if necessary.
5.2 Sample preparation
5.2.1 Injection sample preparation
PREPARE the injection samples according to the provisions specified in the
Article 3.2 of GB/T 2546.2-2003.
The Type 1A samples specified in the ISO 527-2.1993 refer to the Type A
samples that are prepared by using the Type A moulds specified in the standard
of GB/T 17037.1-1997. The Type B samples prepared by using the Type B
moulds refer to the strip samples in size of 80mm × 10mm × 4mm.
The injection samples in size of 60mm × 60mm × 1mm, which are prepared by
using the Type D1 moulds specified in the standard of GB/T 17037.3-2003, can
be used for haze determination.
5.2.2 Preparation of compression molding samples
The preparation of compression molding samples shall be conducted according
to the Article 3.3 of GB/T 2546.2-2003.
5.3 Sample status-conditioning and standard test environment
The sample status-conditioning shall be conducted according to the provisions
of GB/T 2918-1998. The temperature of status-conditioning shall be within the
range of 23°C ± 2°C. The conditioning time shall be at least 40h, but shall not
be longer than 96h.
All the tests shall be conducted in the standard environment (23/50) specified
in the GB/T 2918-1998. The environment temperature t shall be within the range
of 23°C ± 2°C. The relative humidity shall be within the range of 50% ± 10%.
5.4 Physical and mechanical properties
5.4.1 Granule appearance
5.4.6 Notched izod impact strength
According to the provisions of the Article 5.2.1, USE Type B moulds to prepare

on the strip samples within 1h to 4h after the injection molding. PROCESS Type
A notches specified in the GB/T 1843-1996. The strip samples with notches
shall be used as the test samples for conducting the notched izod impact test.
CONDUCT status-conditioning to the test samples according to the provisions
specified in the Article 5.3.
CONDUCT the test according to the provisions specified in the GB/T 1843-1996.
5.4.7 Haze
According to the provisions of the Article 5.2.1, USE Type D1 moulds to prepare
