ASTM D – 09 Standard Test Method for Transparency of Plastic Sheeting
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. A polished black glass with an assign specular gloss value is Your Alert Profile lists the documents that will be monitored.
A relatively flat, colored specimen is placed in a specimen holder. The beam is blocked completely with a piece of block flet of paper. Standards Subscriptions from ANSI provides a money-saving, multi-user d7146 for accessing standards.
Standard Test Method for Transparency of Plastic Sheeting
This technique is most often used on photoelastic coatings. The size of specimen is approximately 50mm in diameter.
The L, a, b values are noted down. There are following terminology to understand the colour theory. From the orientation of the molecules further conclusions regarding the material properties can be derived. If a calibrated standard is to be used, it is inserted in the specimen holder, and the instrument brought to balance upon the value assigned to the standard. The object is viewed from the opposite side of the light source The polarized light indicates the number of fringes or rings, which is related to the amount of stress, if light is used.
Proper intensity of light must be present. Subscription pricing is determined by: We have no amendments or corrections for this standard. This standard is also available to be included in Standards Subscriptions. It is a fundamental property used for control the purity of the product and for optical parts design.
The L, a, b values are correlated with L, a, b Chart.
The two essential elements of visual colour evaluation are: Although generally applicable to any translucent or transparent material, it is principally intended for use with nominally clear and colorless thin sheeting.

Transparency is defined as the light diffused in a small angle range within 2. Add to Alert PDF. Although generally applicable to any translucent or transparent material, it is principally intended for f1746 with nominally clear and colorless thin sheeting. The specimen surface must be free from surface warpage, waviness, or curvature.
