What is the Maximum Tolerance in a 30 m Chain?

By Mandeep Kumar|Updated : July 14th, 2022

The value of maximum tolerance in a 30 m chain is ±8 mm. On the other hand, the maximum tolerance in a 5m and 10m chain is ±3 mm, and in a 20 m chain, it is ±5 mm.

Answer: The maximum tolerance in a 30 m chain is ±8 mm.

There are different types of chains that are used for surveying such as Metric chain, Engineer’s chain, Gunter’s chain, Revenue chain, and Steel band. The simplest method of surveying is chain surveying. In this, the measurements are linear. Galvanized mild steel is used for a manufacturing chain that has a number of links in series. The tools required for chain surveying are offset rod, ranging rod, chain, plumb bob, and tape. The revenue chain has 16 links, the engineer’s chain and gunter’s chain have 100 links whereas the metric chain has 100 to 150 links.

Summary:

What is the Maximum Tolerance in a 30 m Chain?

A 30 m chain has a maximum tolerance value of ±8 mm. The links of the chain can be straightened if the length of the chain is found to be short at the time of testing.
