QBT1474 Drawing Ruler" series of standards consists of seven markings: QR/T 1474.1 Drawing ruler straight ruler QB/11474.2 Drawing room instrument QB/T1474.3 Final drawing ruler scale QB/T1474.4 Final drawing ruler T-square QB.T1474.5 Drawing ruler QB/T1474.6 Drawing ruler template QE1474.7 Drawing ruler only, inspection and adjustment rules: marking, packaging, inspection, and processing. This standard provides four items for QB series 1474. This standard is a reduction of 10B/T1474.4-19926-1992. Compared with QR/T1474.4-1992, this standard has been revised and revised in terms of normative reference documents and test methods. This standard was proposed by the China Association for Sporting Goods Standardization Center. This standard is under the responsibility of the China Association for Sporting Goods Standardization Center. QB/T1474.4—2005 is the standard prepared by Haizhou Stationery Co., Ltd. It is manufactured by Dongguan IQ Stationery Co., Ltd., Shanghai Huakang Sports Products Co., Ltd., Guangzhou Huijian Office, and other Japanese products manufacturers, including Tianyi Sports Products Co., Ltd. and 1 Oil Stationery Factory. This standard was first issued in April 1992, and this is the first revision: This standard is implemented by the Ministry of Light Industry, replacing the original light industry standard QB/T1474.4-2009 issued by the Ministry of Light Industry.

2 Normative non-application documents
The above-listed clauses become non-approved clauses through the month of this standard. All documents with the date of application are called applicable documents after the test. The receipt (six pairs of teeth are not aligned or revised) are not applicable to this standard. However, the parties that have reached an agreement on the standard are encouraged to study whether to make these parts effective. The reference parts are not considered! The new ones are suitable for the standard: QB/T1474.200 Drawing size code, inspection planning, marking, packaging, delivery, storage 3 classification

Chinese chemical A cross-correlation
: The surface of the ruler is sensitive to the freezing point, the effect of the effect is not clear, and the head, impurities and bubbles are not clearly indicated. 4.6.2
4. 6.3 The surface should be satisfactory and effective.
1B4 The surface should have a small pressure line
5 The edge should be slippery: there should be no missing
5 Test method
Test conditions
The product should be tested after 24h in an environment with a temperature of ± 2°C. 5.2 The length and width of the line pattern are different. The width difference is measured by the actual and speed numbers (mm). The results should be consistent with the appearance of the platform. 5.3 The straight edge and the straight edge are measured according to the point. The length of the edge and the main size are measured in the month. The main size is the most important. The result is consistent with the production 4.2: 5.4 The surface of the German Qing
chooses the micro-precision card. The scale surface should be on the main size. The work surface and the T-pole are called the consideration of the large interval: Bin language set should be consistent with the table specification
55 The working edge straight line is installed
and the main size is relatively sensitive to the first-level precision single level. The room scale is used to measure the action and the half or layer of human stimulation. The result is consistent with the implementation Table 3 starts
5 indication deviation
full length indication version, may be core engineering scale of the continuation of a scale of equal position and teaching alignment, but this scale end from the steel only read to eliminate: for the full length of the careful source difference.
electric use value deviation car: the brick material written tile fall so careful for the real number of the heart to read the ratio and determination note but the value in the table 4 is consistent with the current
