When purchasing polyethylene tarpaulin, size is an important selection indicator. According to plastic tarpaulin wholesalers, there are generally six points that need to be paid attention to when measuring polyethylene tarpaulin:
(1) Measurement of rope diameter: According to GB/T8834-2006, take the average of three measurement data as the measurement result, accurate to 0.1mm.
(2) Measurement of rope length: measure the length of the rope with a steel tape with a division value of 1mm and a measuring range larger than the measured size. The length of the angle rope and the end rope are the distance from the end of the rope loop to the end of the rope, waist The length of the rope and the pressure rope is the distance between the two ends after unfolding. Take the average of three measurement data as the measurement result, accurate to 10mm.
(3) Measurement of eye circle specifications: Measure 3 eye circles with a vernier caliper, and take the average of the three measurement data as the measurement result. The inner and outer diameters are accurate to 0.1mm, and the thickness of the steel plate is accurate to 0.01mm.
(4) Measurement of eye circle spacing: use a steel tape with a division value of 1mm and a measuring range larger than the measured size to measure the distance between the centers of adjacent eye circles, and take the average of the three measurement data as the measurement result, accurate to 10mm.
(5) Measurement of the length and width of the tarp: use a steel tape with a division value of 1mm and a measuring range larger than the measured size to measure the length and width three times at equal intervals, and take the average value as the measurement result, accurate to 10mm.
(6) Measurement of other dimensions: measure with a steel tape with a division value of 1mm and a range larger than the measured size, and take the average of the three measurement data as the measurement result, accurate to 1mm.
