Cotton planting and Determination of film thickness limits
1 Scope
This standard specifies the limits for cotton planting and film thickness measurement method.
This standard applies to cotton planting mulch.
2 Film thickness limits
Cotton planting film thickness limit of not less than 0.008mm.
3 Determination
3.1 measuring instrument
3.1.1 thickness gauge with a resolution of 1μm.
3.1.2 The meter should have a planar surface and a lower surface measuring surface flat or convex surface on the measurement, all measuring surface should be
Polished surface.
3.1.3 the vertical measuring surface is a plane/plane, each measuring surface diameter should be 2.5mm ~ 10mm between two parallel plane is not less than
5μm, measured surface should be adjusted to meet the above requirements. Measurement should face between the load applied to the specimen in 0.5N ~ 1.0N.
3.1.4 When the vertical measuring surface is convex/plane, the radius of curvature measurement should be between 15mm ~ 50mm in diameter should be measured at the surface
Not less than 5mm, the face should be measured between the load applied to the specimen in 0.1N ~ 0.5N.
3.1.5 transfer output measured values \u200b\u200bcan use mechanical method (micrometer), an optical method (using a mirror meter) or electrical method (inductive method)
A variety of methods.
3.2 Preparation of the sample
Away from the longitudinal ends of the sample at about 1m, transversely across the width of the test specimens, specimen width 100mm. Except for the submission of folding or packing
Stack samples, specimens should be free of wrinkles, nor should other defects.
3.3 Determination of step
3.3.1 sample at (23 ± 2) ℃ condition conditioning at least 1h, a thin film of humidity, conditioning time and the environment should be the test material
Norms or negotiated by the supply and demand sides.
3.3.2 The measurement should be checked before each measurement sample surface and measuring instrument should be no oil, dust and other contamination.
3.3.3 should be checked before measuring gauge zero. After each set of sample measurements should re-examine its zero point.
3.3.4 should be measured down gently probe to avoid deformation of the specimen.
3.3.5 equidistant length measuring method to determine the position of the point of thickness, as follows.
a) the sample length is less than equal to 300mm, measuring 10 points;
b) in the sample length between 300mm ~ 1500mm, measuring 20 points;
c) the sample length is greater than equal to 1500mm, measured at least 30 points.
The samples did not cut edges should start measuring 50mm away from the edges.
3.4 Data Processing
Measuring the sample thickness is the arithmetic mean of all the measurements.
