Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part

1.Structure and Drafting Rules of Standardization Documents" drafted. This document replaces GB/T 13982-2011 "Reflection and Transmission Screens". Compared with GB/T 13928-2011, except for structural adjustment In addition to editorial changes, the main technical changes are as follows:

--- Changed part of the "scope" (see Chapter 1, Chapter 1 of the.2011 edition);

--- Added some terms and definitions (see 3.2, 3.13, 3.18~3.20);

--- Changed the "classification" of the screen (see 4.2,

4.2 of the.2011 edition);

--- Increased the requirements and test methods for the polarization ratio of the transmission screen (see 5.25.2, 6.24.2);

--- Added the requirements and test methods for "restricted substances" (see 5.26, 6.25);

--- Changed the brightness coefficient requirements of different types of screens (see 4.2, 5.1.1, 4.2,

5.1.1 of the.2011 edition);

--- Added quantitative requirements and test methods for screen "color reproduction" (see 5.5, 6.4);

--- "Color temperature difference" in "Reverse (transmitted) light color" is listed as a separate technical requirement, and the requirements are improved (see 5.6);

--- Changed the "durability" requirements and test methods (see 5.13, 6.12, 5.12,

6.10 of the.2011 edition);

1 Scope

GB/T 13982-2022 is the Chinese national standard on reflective and transmitting projection screens, in the field of image technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 14 October 2022 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2023. Classification: ICS 37.060.10, CCS N42. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.
