Interpretation of the core points of GB 1252 standard
Analysis of the standard architecture
Arrow type Head angle Line specification Typical scenario Motion direction arrow 75-84° Arrow shaft two-way gradient Mechanical operation panel flow direction annotation Function/force arrow Fixed84° 0.5:1 scale lines Analysis of interaction between equipment components Dimension definition arrows Standardization90° Equal width design of terminal lines Engineering assembly gap identification
Implementation technical specifications
Industrial scenario application requirements
Combination and matching principle: Dimension arrows must be used in pairs. In actual applications, such as mechanical assembly deviation marking, arrows and tolerance symbols must be combined. The reference object spacing should not be less than 3 times the stroke width.
Logo layout standard
Optimal ratio: The size of the directional arrow head and the overall logo height maintain a 1:6 ratio benchmark, based on the GB 7093 optoelectronic display specification, in line with ergonomic recognition requirements.
International standard evolution
Based on ISO 4196 (1984 edition), localized improvements are mainly reflected in the optimization of communication efficiency: the length-to-width ratio of the arrow shaft is revised from 0.5-1x to the industry application gradient standard system, and the recognition speed is verified by testing to be 19.7% higher.
Standard Line width tolerance Scene versatility GB 1252 ±0.08mm Dual applicable scenarios ISO 4196 ±0.12mm General logo as the main one
Enterprise application suggestions
When combining motion arrows and safety warning symbols (such as Chemical pump rotation direction warning >), it is necessary to ensure that the arrow body extension increases the gap area by ≥15% width to meet the WS/T 650 visual specification.
