What is a proof test?
In its simplest form, load testing involves applying a load to a structure or piece of equipment. A proof test is a type of load test that demonstrates the fitness of a load-bearing structure. Such tests may be required as part of a thorough examination in line with Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) that place duties on people and companies who own, operate or have control over lifting equipment.
LOLER places emphasis on the experience of a competent person, who makes an informed decision as to what is appropriate based on their training. They determine if a proof test is necessary or helpful to assess a piece of lifting equipment.
A proof test is usually expressed as a percentage of the working load limit (WLL) that equipment is designed to withstand.
The exact requirements of proof testing and the extent of each test can vary depending on standards, equipment or industries involved, as well as individual requirements from customers or as part of manufacturers’ own quality controls.
How to proof test?
Numerous load-testing applications worldwide require a load cell to verify the load applied, from crane testing using water bags and a tension load link to cylinder testing using a hydraulic test rig and a compression load cell.
A load cell allows the test to be accurately measured and recorded. In safety critical industries the requirement to document test procedures and results has never been greater as users of lifting equipment call for more traceability and audit trails.
Proof testing equipment
Straightpoint manufactures a variety of equipment that can be used for proof testing. As referenced at the outset, its Proof Test plus (or SW-PTP) software records data gathered by a Straightpoint Radiolink Plus load cell, load shackle or compression load cell. It then creates a pass or fail certificate that includes test data and graphs charting data from the load versus time throughout a test.
Information can be printed out directly as a PDF report, electronically transmitted or fed to an information centre in the cloud. It is important that there is traceability of proof test certification and that the load cell that did the test was accurate and calibrated. Where a load test is deemed beneficial the aim of Proof Test plus is to make that process more efficient.
