ACCEPTANCE TESTING
835.33.01 INTRODUCTION
1. Paintwork shall be subject to visual examination and measurement of the
dry film thickness after the application of each type of coating. Galvanised
surfaces shall be subject to visual examination and measurement of the
galvanising thickness as detailed in this clause.
835.33.02 VISUAL EXAMINATION
1. All surfaces shall be subject to a visual examination after blast cleaning and
after priming and after application of top coats. Each coat of paint shall be
free of cracks and wrinkles and blisters and lumps or any other defects.
Whenever these defects occur the whole paintwork system of the affected
area shall be removed by abrasive blast cleaning as set out in Clause
835.26 and replaced at the Contractor's expense.
835.33.03 MEASURING INSTRUMENT
1. The Contractor shall measure the dry film thickness using a non-destructive
type film thickness gauge. The gauge shall be either:
a. A magnetic instrument used in accordance with AS 1580 - "Methods
of Test for Paints and Related Materials" Method 108.1 except that
gauges of the 'Tinsley' type shall not be used.
or
b. An instrument operating on the eddy current principle and used in
accordance with British Standard 3900 - "Methods of Test for Paints"
Part C5.
835.33.04 PROCEDURE
1. In order to determine the dry film thickness of each coating the following
procedure shall be adopted:
a. Dry film thickness gauges shall be calibrated using shims of known
thickness set on the blast reference sample. The calibration
procedure shall consist of taking not less than 30 readings on the
shim on the reference blast sample and from these determining the
mean reading. This mean reading shall be subtracted from the
known shim thickness to produce a correction factor which shall be
added algebraically to all subsequent readings of dry film paint
thickness in order to obtain the true "above peaks" value.
Alternatively the gauge itself may be adjusted to yield the
appropriate reading equivalent to the known shim thickness. In this
case not less than 30 readings shall be taken until the gauge mean
reading is equivalent to the known shim thickness.
This calibration shall be maintained throughout the duration of the
contract except where blasting techniques or procedures are varied
in which case the calibration procedure shall be repeated.

Page 12 of 18
Specification 835 Protective Treatment of Steelwork – 04/10144 Issued 04/05/2017
b. Readings shall subsequently be taken of the total dry film thickness
after the application of each type of coating.
c. At each stage the Contractor shall use the average reading for that
surface.
d. The dry film thickness for any coating is the difference between the
values obtained for this coating and the average total dry film
thickness at the completion of the preceding coating.
e. Film thickness measurements will be taken at random to suit the
shape of the area being tested and the number of such
measurements shall be given as below:
i. For large flat surfaces like the webs and flanges of beams
the number shall be one per square metre.
ii. For hand railing panels the number shall be six per linear
metre.
iii. For guard railings the number shall be four per linear metre.
iv. For guardrail posts the number shall be four per post.
2. For assessing the compliance of a coating with the thickness requirement of
this Specification all measured values of the dry film thickness on each
surface shall equal or exceed the specified minimum dry film thickness for
that coating. Surfaces not meeting this requirement shall receive further
coats of primer or finishing coat as appropriate to build up the paint
thickness required.
835.34
PROTECTION
1. The paint system shall be fully cured before any components are handled.
It shall be properly protected during all transport and erection procedures to
maintain it in a clean and undamaged condition. In particular proper
precautions are to be taken during lifting operations to ensure a minimum of
damage is caused by slinging or guying or supporting or similar operations.
835.35
SITE REPAIRS
1. Repairs to areas of damaged paintwork shall be carried out at the time of
application of the final finishing coat except that where corrosion of the steel
may occur adequate cleaning and protective priming shall be carried out
immediately.
2. Areas of paintwork which have been damaged and areas of site welded
connections shall be cleaned by power wire brush to AS 1627 Part 2 Class
3 followed by abrasive paper to provide a surface profile. In addition the
edge of the surrounding undamaged paint shall be feathered with abrasive
paper.
3. In areas of site welded connections all weld splatter and slag shall be
removed by mechanical means and all sharp edges and rough welds shall
be rounded off before cleaning.
