Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 4028-1994 "Test position marker timing equipment" compared with GB/T 4028-1994, the main editor
Changes are as follows.
--- Adjust the order in Chapter 1 of the statement;
--- Increase in Tables 1 to 3 of table title.
This standard uses the translation method identical with ISO 3158. 1976 "chronographs inspection position marker."
This standard made the following editorial changes.
--- To Chapter 1, "Scope" fully reflects the content standards, supplemental comment text on Article 4 Content of the description;
--- In order to facilitate text editing and more neatly arranged, we will examine the location of the content layout to a table.
The standard proposed by China National Light Industry Council.
This standard by the National Standardization Technical Committee clocks (SAC/TC160) centralized.

--- GB/T 4028-1994.
Timing equipment inspection location marker
1 Scope
This standard specifies the definitions and timing equipment inspection mark position, regardless of the timing equipment type, structure or size.
NOTE. This standard applies to the position of the pointer timing equipment inspection mark, also applies to the inspection position mark timekeeping instrument or movement unconventional dial.
2 Definitions
Timing equipment or movement position is based on the gravitational direction opposite to the Z-axis direction based (Figures 1 and 2), with the angle λ
And θ to mark defined angle λ and θ as follows.
2.1 angle λ is timing devices around the X-axis perpendicular to the dial counterclockwise angle of rotation (see Figure 1).
λ ranges. 0 ° ≤λ < 360 °.
2.2 angle θ is timing equipment around an axis perpendicular to the ZX plane rotation angle (see Figure 2).
a) θ > 0 ° is the highest point on the dial away from the moment the viewer direction of rotation;
b) θ < 0 ° is the highest point on the dial is rotated in the moment direction towards the observer;
Range c) θ is. -90 ° ≤θ≤ 90 °.
Figure 1 Figure 2 Angle λ angle θ schematic
2.3 When λ = 0 ° and θ = 0 °, should coincide with the Z-axis direction (for unconventional dial timing devices or via the shaft of 6.00 and 12.00
Heart, Chapter 4 shall be specified).
