This procedure is based on OIMLR35-1:2007 (E) "common tool length measurement" requirement, in accordance with
JJF1002-2010 requirements "national verification procedures to write the rules," the on JJG 4-1999 "steel tape measure" into
Line revision. Compared with JJG 4-1999 "steel tape measure", in addition to editorial changes, the major technical changes are as follows:
--- Remove Strapping steel-related content;
--- Significant increase in the number of steel tape, steel tape rack outline drawings and related metering performance requirements;
--- Increasing the arc foot with steel tape tension at the time of verification is not specified requirements;
--- Increased requirements indication error test, applying a different tension according to the length of the test station;
--- Increased requirements for steel tape subsequent verification error of indication; adjust the steel tape measure centimeter division shows the maximum allowable value
Requirements error;
--- Modified sounding steel tape indication error, measurement error performance requirements of the tension, the abolition of grade Ⅰ, Ⅱ grade
Sounding steel tape of classification requirements;
--- Increasing the error indication data processing formulas;
--- Increasing the length of the steel tape test station requirements;
--- Increased sounding steel tape measure zero error test the metering performance requirements;
--- Removed certified by the stamp requirement.

3.1 tension tension
Straighten foot tape measure belt tension when applied.
3.2 dipstick mound dip-weight
Connected to the foot with the lower end, the quality can be maintained with a heavy foot plumb.
4 Overview
Ordinary steel tape is used to measure the length of the measuring object. Sounding steel tape measure with a ruler by the mound and dipstick combinations
Body to measure the depth of the liquid composition dedicated gages.
The main structural steel tape measure to have a certain elasticity of the entire foot zone (with feet flat or curved foot zone), or roll the metal
Within the framework of foot boxes or plastic material. Steel tape end fitted with ring-pull or hook feet; restrained with tape attached to the control rule
Button means of rolling; steel tape ruler sounding dipstick end with a mound, it is connected with both feet can be fixed,
It may be removable.
Steel tape measure its structure is generally divided into A, B, C, D, E, F six forms, its shape as shown in FIG. 1 to 6 respectively
