China is one of the most polluted regions in the world with high aerosol loading, following measurements of Chinese Sun Hazemeter
Network (CSHNET; Xin et al.
Transmittance haze and clarity of the neat PLA and PLA/ ATBC/GPOE blown films were measured in an Optical Hazemeter
WGT-S system (Shanghai Precision and Scientific Instrument Co.
Gloss and haze (20[degrees]) measurements were taken prior to and just after AMTEC Kistler testing using a Micro-haze Plus Hazemeter
from BYK-Gardner (Columbia, MD, USA).
The light transmission and haze of EVM vulcanizates were measured with 1 mm sheet on a spherical hazemeter
according to Chinese Standard GB2410-80.
In this way, a simulated gloss-meter or hazemeter
can be used to determine the gloss or haze of any arbitrary BRDF.
The firm also offers the XL-211 Hazegard hazemeter
, which measures and displays the percentage of transmission haze in films and other transparent materials.
The sunphotometers are calibrated using Langley plot calibration (Shaw 1976) and transfer calibration (Brooks and Mims 2001), which is same as the Chinese Sun Hazemeter
Network (Xin et al.
Transmittance and haze of PLA/ACR blends about 1.0 mm in thickness were carried out in an Optical Hazemeter
WGT-S system (Shanghai Precision and Scientific Instrument Co., China).
Results obtained with the high throughput method showed an excellent correlation to results obtained using a hazemeter
, according to ASTM D 1003.
Also on display were a Spectrogard II spectrophotometer and an XL-211 Hazegard Hazemeter
. BYK-Gardner Inc., 2435 Linden Lane, Silver Spring, MD 20910; (301) 495-7150; Fax (301) 585-4067.
Optical properties such as haze, total transmission, and diffuse transmission of samples were measured in a 1-mm-thick injection molded plaques on ColorQuest II Hazemeter
(HunterLab, USA) as per ASTM D1003-95 standard.
