MRTS03 Table 49.5 — acceptance (pull-out) testing
Up to 50 nails: 3 tests · 51–100 nails: 6 tests · Over 100 nails: 6%
Required acceptance tests
6
51 to 100 nails — minimum 6 pull-out tests
Suitability tests
Not specified
MRTS03 prescribes a single acceptance (pull-out) regime at 1.5 × working load. Any pre-construction sacrificial testing is set by the designer or Superintendent.
How it works
The testing rates explained
Both specifications require testing on a proportion of installed production nails, distributed across soil units, wall panels and installation crews rather than clustered in one lot.
01
Count the production nails
Take the total permanent nails or anchors in the lot as shown on the shoring design drawings.
02
Apply the specified rate
MRTS03 Table 49.5: 3 tests below 50 nails, 6 tests for 51–100, and 6% above 100. TfNSW TS 02168.1: a minimum 3% of working nails for acceptance, plus sacrificial suitability nails at the greater of 1% or two per ground type.
03
Distribute the tests
Spread tests across soil horizons, wall heights and shifts so the sample is representative of the whole lot.
