Aeronautical glass optical performance test method1 ScopeThis standard specifies the terms and definitions of aerospace glass, test environmental conditions, haze, light transmittance, optical distortion, optical angular deviation and binocular Test method for optical properties such as parallax. This standard applies to organic or inorganic aerospace transparent parts of single or laminated structure.2 Normative referencesThe following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 2410 transparent plastic transmittance and haze determination3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Transmittance luminoustransmittance The ratio of the luminous flux through a transparent material or transparent member to the luminous flux incident on a transparent material or transparent member is expressed as a percentage. 3.2 Haze haze The ratio of the scattered light flux to the direction of the incident light transmitted through the transparent material or the transparent member to the direction of the incident light is expressed as a percentage. 3.3 Optical distortion opticaldistortion When viewed through transparent materials or transparent parts, the geometry of the object is deformed. 3.4 Optical angular deviation opticalangulardeviation The amount of change in the angle of light travel after passing light through a transparent material or a transparent piece. 3.5 Binocular parallax binoculardeviation The difference between the two optical angular deviations when the eyes are viewed through the transparent material or the transparent member. Note. In the measurement, the binocular parallax is the optical angular deviation produced by two points of the two parallel rays passing through the glass representing the average distance (63.5 mm) of the eyes of the person. Difference.4 Test environmental conditionsExcept for special requirements, the test shall be carried out under the following environmental conditions. a) Ambient temperature. 20 °C ± 5 °C; b) relative humidity. 40% RH ~ 80% RH; ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 37831-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 37831-2019_English as soon as possible, and keep you informed of the progress.
