2 Normative reference documents

This document has no normative references.

3 varieties

3.1 smart glass smartglass Under the action or excitation of external energy fields such as electricity, light, heat or special gases, it can cause transmission, reflection or absorption of light in a specific waveband. Glass products whose chemical properties have changed and can remain or be reversed after these effects are eliminated. 3.1.1 active smart glass activesmartglass Glass products that change their optical properties under the controlled action of an external electric field or certain gases. 3.1.2 Passive smart glass passivesmartglass Glass that changes its optical properties when excited by the natural environment temperature field or light radiation without consuming any electrical energy products. 3.2 photochromic glass photochromicglass Glass that causes reversible reactions in certain materials under photon excitation, thereby causing changes in optical properties in specific wavelength bands products. 3.3 thermochromic glass Under the influence of the temperature field of the natural environment, the phase change, structure or aggregation state of the material is reversibly changed, which can cause light in a specific waveband. Glass products with changed chemical properties. 3.4 electrochromic glasselectrochromicglass Under the action of an external electric field, reversible chemical reactions occur inside certain materials, and molecules or particles are oriented and arranged, resulting in changes in optical properties. Altered glassware. 3.4.1 suspended particle dimming glass suspended-particledevices Glass products whose optical properties change are made by using the principle that suspended particles will be oriented when an electric field is applied.
