適用范圍: This International Standard defines the test equipment and procedures to be used to determine the performance of bar code scanning and decoding equipment. It deals with bar code scanning and decoding equipment both as integrated reading systems and as discrete units. It defines performance of the equipment in a particular configuration (e.g. a specific model) irrespective of the individual components used. It also defines in a normative annex operational parameters for the test equipment, and describes, in an informative annex, a means of classifying scanners.

術(shù)語(yǔ)	描述
接觸式掃描儀 Contact scanner	一種掃描器，其掃描動(dòng)作發(fā)生在掃描器與符號(hào)的實(shí)際或近接觸中（例如 wand 或 light pen）。
解碼冗余度 Decode redundancy	在解碼器接受有效解碼之前獲得的相同解碼的預(yù)定數(shù)量。例如，解碼冗余度為 2 需要兩個(gè)相同的解碼。
出口窗口 Exit window	從閱讀圖中測(cè)量數(shù)據(jù)點(diǎn)的位置，在掃描器出口端最近的點(diǎn)。

條碼掃描儀單軸、雙軸、三軸讀取模式	用于掃描和解碼條碼的設(shè)備，支持不同方向和角度的讀取。
