净长度的测定
1 范围
本标准规定了测定环形输送带(拼接)净长度的方法。
本标准适用于除含钢丝绳增强层以外所有构造的输送带。
本标准不适用于ISO 21183-1[3]规定的轻型输送带。
2 装置
2.1 钢卷尺测量,标有毫米刻度。
为了确保测量的准确性,卷尺应经过校准或计量检定。
3 程序
将环形输送带展开,使其平坦且不受张力。
如图1所示,仅用带上的平坦部分,在内壁的一边画一点(即点A)作为测量起始点。
按照如下步骤沿着带子的平坦部分,标出点B。
a) 对于周长不大于30m的带,除最后一次测量的长度可能会少于周长的1/4外,每一次的测量
应在周长的1/4和1/3之间。
b) 对于周长大于30m的带,除最后一次测量的长度可能不足7.5m外,每一次的测量应在7.5m
和带周长的1/3之间。
测量并记录A、B 两点的距离AB。
滚动带子,只沿着带子平坦部分的内壁连续测量。将每个测量结果分别记为AB、BC、CD 等,最后
一直测到XA。
在出现争议的情况下,当供应商和客户达成协议时,测量宜按照ISO 18573[2]中的一个标准环境来
进行。

Preface
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard uses the translation method equivalent to the international standard ISO 16851..2012 "fabric core conveyor belt conveyor belt (splicing) net length
Of the determination "(English version).
This standard is proposed by the China Petroleum and Chemical Industry Association.
This standard is nationalized by the National Technical Committee on Conveyor Belt with Standardized Technical Committee (SAC/TC428/SC1).
The drafting unit of this standard. Shandong Xiangtong Rubber & Plastic Group Co., Ltd., Qingdao Shinkansen Technology Consulting Co., Ltd., Shandong Daoyuan New Energy Section

Fabric Conveyor Belt Conveyor Belt (Splicing)
Determination of net length
1 Scope
This standard specifies the method of determining the net length of the endless conveyor belt (splice).
This standard applies to all conveyor belts other than steel wire reinforcement.
This standard does not apply to light conveyor belts specified in ISO 21183-1 [3].
2 device
2.1 steel tape measurement, marked with a millimeter scale.
In order to ensure the accuracy of the measurement, the tape should be calibrated or measured.
3 procedures
Expand the endless conveyor belt so that it is flat and free from tension.
As shown in Fig. 1, only a flat portion of the belt is used to draw a point (i.e., point A) on one side of the inner wall as a measurement starting point.
Follow the steps below to mark the point B along the flat portion of the tape.
a) For bands with a circumference of not more than 30 m, except that the length of the last measurement may be less than 1/4 of the circumference,
Should be between the quarter 1/3 and 1/3.
b) For bands with a circumference greater than 30 m, except that the length of the last measurement may be less than 7.5 m, each measurement shall be at 7.5 m
And between the circumference of 1/3.
Measure and record the distance between two points A and B AB.
The rolling belt is continuously measured only along the inner wall of the flat portion of the belt. Each measurement result is denoted as AB, BC, CD, etc., and finally
Always measured XA.
In the event of a dispute, when the supplier and the customer reach an agreement, the measurement should be in accordance with ISO 18573 [2] in a standard environment
get on.
