Foreword
This Standard modified EN 12608 “Unplasticized polyvinyl chloride (PVC-U)
profiles for the fabrication of windows and doors - Classification, requirements
and test methods” (2002 EN version) developed by European Technical
Committee for Standardization; and revised GB/T 8814-1998 “Unplasticized
polyvinyl chloride (PVC) profiles for the frames of doors and windows”.
The main differences between this Standard and EN 12608 are as follows.
- CHANGE climate classification to time classification of artificial weathering
aging (known as aging for short hereafter);
- Part of the test methods adopt the national standard;
- ADD Chapter 7 “Inspection rules” and Chapter 9 “Packing, transport, and
storage”;
- ADD the requirement for deviation from straightness of gauze fan;
- DELETE Appendix B “Allowable deviation of standard colors”;
- DELETE Appendix C “Calculation methods for determination of radiation
intensity and exposure time of artificial aging test”.
The main differences between this Standard and GB/T 8814-1998 are as
follows.
- DELETE the requirements of Rockwell hardness, tensile yield strength,
elongation at break, oxygen index, high-low temperature repeated
dimensional change rate;
- ADD the classification of aging time, the classification of drop hammer
impact of main profiles, and the classification of wall thickness of main
profiles;
- ADD the requirements for the material of profiles;
- For main profiles, ADD the requirement of weldability;
- For main profiles, ADD the requirement of permanent marking;
- Some items add the requirements for auxiliary profiles;
- DETERMINE the sight and non-sight surfaces of profiles;
- INCREASE the aging time to 4000 h or 6000 h;

3 Terms and definitions
6.4 Deviation from straightness
6.4.1 Sample preparation
From each of three profiles, CUT out a sample with a length of (1000 ଴ାଵ଴) mm.
6.4.2 Test procedures
PLACE the concave surface of the sample on a Level 3 or higher standard
platform. USE a feeler gauge with a precision of at least 0.1 mm to measure
the maximum clearance between the profile and the platform; then, MEASURE
the surface perpendicular to the first measurement; TAKE the maximum of the
three samples.
6.5 Mass of main profile
6.5.1 Sample preparation
From each of three profiles, CUT out a sample with a length of 200 mm~300
mm.
6.5.2 Test procedures
USE a balance with a precision of not less than 1 g to weigh the mass of the
profile; USE a measuring tool with a precision of at least 0.5 mm to measure
the length of the profile; TAKE the average of the three samples.
6.6 Dimensional change rate after heating
6.6.1 Sample preparation
In machining manner, from each of three profiles, CUT out a sample with a
length of (250±5) mm; on the sight surface specified by the sample, DRAW two
marking lines with a spacing of 200 mm. The marking line shall be perpendicular
to the longitudinal axis. The distance between each marking line and the end of
the sample is about 25 mm. And in the middle of the marking line, MARK the
measuring line which is perpendicular to and intersects the marking line. A pair
of marking lines are made on each of the two opposite largest sight surfaces of
main profile; while the marking line is made on only one surface of auxiliary
profile.
6.6.2 Test equipment
Electrothermal blower box; thermometer with a division value of 1 °C.
6.6.3 Test procedures
in an electrothermal blower box with a temperature of (150±2) °C; PLACE it for
30 ଴ାଷ min; TAKE it out together with the glass plate; COOL it to room
temperature; and visually OBSERVE whether bubbles, cracks, pits, or
separations occur.
6.9 Aging test method
The aging test, according to the provisions of Method A in GB/T 16422.2-1999,
is carried out. The black panel temperature is (65±3) °C; the relative humidity
is (50±5) %. The aging surface is the sight surface of profile. The aging time of
Classification M is 4000 h; the aging time of Classification S is 6000 h.

breadth b is (6.0±0.2) mm. The height h is the original height of profile. The
notch bottom radius rN is (0.25±0.05) mm. The notch remaining breadth bN is

αcN - Impact strength, in kilojoules per square meter (kJ/m2);
Ec - The calibrated energy absorbed when the sample fractures, in Joules (J);
h - The height of sample, in millimeters (mm);
bN - The bottom remaining breadth of sample notch, in millimeters (mm).
The inspection results of appearance and dimension are determined according
to Table 6.
7.3.1.2 Determination of profile and material properties
In the test results of profile and material properties, if there are unacceptable
items, from the original batch, it shall randomly draw double samples. The items
shall be re-inspected. If the re-inspection results are all acceptable, the profile
and material properties shall be acceptable; if there are still unacceptable items
in the re-inspection results, the profile and material shall be unacceptable.
7.3.2 Determination of acceptable batch
If the inspection results of appearance, dimension, profile, and material
properties are all up to standard, then the batch shall be acceptable; if one item
is not up to standard, the batch shall be unacceptable.
8 Marking
8.1 Marking
8.1.1 Protective film of sight surface
The sight surface of main profile shall be covered with protective film. On the
protective film, there shall be at least this Standard’s code, factory name, factory
site, telephone, trademark, etc.
8.1.2 Certificate of qualification
The profile, when it comes out of factory, shall have a certificate of qualification.
The certificate of qualification shall include at least the mass per meter,
specifications, and production date.
8.2 Permanent marking of main profile
The main profile, along the length of the profile on the non-sight surface, at
intervals of 1 m, shall have at least one set of permanent markings, which shall
include classification of aging time, classification of drop hammer impact, and
classification of wall thickness, etc.
9 Packing, transport, and storage
9.1 External packing
