안녕하세요 UPC(주) 품질관리부에 근무 하는 오정연입니다.

저희 회사에서 납품 하는 업체에서

내후성 test 후 물성 강도를 측정하는 시험을 해야한다고 통보 받았습니다.

현제 저희 회사 장비로는 실험이 불가능하여 실험 가능 여부를 알고자 합니다.

첨부파일에서 4.1.1 4.1.3를 할수 있는지 알고 싶습니다.

4.0 TEST METHODS

4.1 Weathering Tests: This test method applies to
polymeric-based barriers.

4.1.1 General: Three samples, each measuring 18
inches by 48 inches (457 mm by 1219 mm), are required.
One sample shall be used for preparing control specimens
and shall be conditioned at 73/F (23.7/C) and 50 percent
relative humidity for a minimum of 40 hours. Two samples
shall be exposed to ultraviolet light, followed by exposure to
accelerated aging in accordance with Sections 4.1.2 and
4.1.3 of this criteria.

4.1.2 Ultraviolet Light Exposure: Two 18-inch-by-48-
inch (457 mm by 1219 mm) samples shall be exposed to
light from ultraviolet sun lamps for 210 hours (10 hours per
day for 21 days) in an enclosure as depicted in Figure 1.
Ultraviolet light exposure shall be directed on the sample
surfaces that will be exposed to sunlight in normal
application. Lamps and enclosure shall be adjusted so the
specimen temperature is between 135/F and 140/F (57/C
and 60/C). Sunlamp bulbs shall be General Electric Type
H275 RUV (275 W) or equivalent bulbs, providing UV
characteristics of 5.0 W/m2/nm irradiance at a wavelength of
315 to 400 nm at 1 meter.

4.1.3 Accelerated Aging: Three 10-inch-square (254
mm2) specimens shall be cut from the ultraviolet-lightexposed
samples. The three specimens shall be subjected
to 25 cycles of drying and soaking as follows:
1. Oven drying at 120/F (49/C) for three hours, with all
surfaces exposed.
2. Immersion in room-temperature water for three
hours, with all surfaces exposed.
3. After removal from the water, specimens are blotted
dry, then air-dried for 18 hours at a 75/F ± 5/F (23.8/C ±
2.8/C) room temperature, with all surfaces exposed.
