The traditional and not so common techniques used to mitigate

the onset and progress of corrosion are all based on the classic

methods: change materials, change the environment, apply a

coating or use electrochemical controls. The effectiveness of each

method can be observed using a corrosion management plan and

measured using a programme such as an inspection survey or

more sophisticated corrosion monitoring.

Corrosion monitoring can be defined as any method used to

observe, measure and analyse the progress of corrosion. It

involves myriad variables – materials, measurement techniques,

instrumentation, budgets, standards, logistical support, data

analysis, communication and, critically, information management.

Real value is gained from corrosion monitoring initiatives when

the information gathered over a period is translated into effective

corrosion mitigation/control programmes.

Each local seminar programme will be available by visiting

www.corrosion.com.au or by emailing aca@corrosio

n.com.au.

Alternatively, this will be emailed to you following your registration.

The registration form can be found on the reverse of this page.

The traditional and not so common techniques used to mitigate

the onset and progress of corrosion are all based on the classic

methods: change materials, change the environment, apply a

coating or use electrochemical controls. The effectiveness of each

method can be observed using a corrosion management plan and

measured using a programme such as an inspection survey or

more sophisticated corrosion monitoring.

Corrosion monitoring can be defined as any method used to

observe, measure and analyse the progress of corrosion. It

involves myriad variables – materials, measurement techniques,

instrumentation, budgets, standards, logistical support, data

analysis, communication and, critically, information management.

Real value is gained from corrosion monitoring initiatives when

the information gathered over a period is translated into effective

corrosion mitigation/control programmes.

Each local seminar programme will be available by visiting

www.corrosion.com.au or by emailing aca@corrosio

n.com.au.

Alternatively, this will be emailed to you following your registration.

The registration form can be found on the reverse of this page.

Asset integrity is an important factor in the efficient

operation of mining facilities; particularly when poor

water quality (hypersaline conditions), frequent wet/dry

cycling, high UV, high temperature and excessive debris

collection on exposed surfaces are almost continuous

factors promoting corrosion and durability issues to

metallic, concrete and non-metallic structures on site.

Consequently there are many strategies (simple and

not so simple) being employed to ensure that the plant

items are operated in a safe, efficient, durable and cost

effective manner.

These strategies include the use of management

systems as well as the physical processes of design,

fabrication and corrosion management methods. All of

these strategies are important and are inter-related.

The Australasian Corrosion Association’s Mining

Industry Technical Group is hosting a seminar to

enhance corrosion awareness and to encourage

dialogue on the various aspects of efficiently mitigating

corrosion, with a special focus on the peculiar

demands imposed by mining and mineral processing

activities. The seminar will be of value to anyone

(Maintenance and Operations related managers,

operators, superintendents, supervisors etc.) involved

in optimising mining operations to ensure that plant

safety and availability is not compromised by corrosion.

Certification Program Working toward Professional Development in Corrosion

The Australasian Corrosion Association Inc

Work experience and work in responsible chargeWork experience in corrosion or corrosion

related field is defined as practical experience

in corrosion mechanisms, causes, control and

monitoring. It covers the investigation, design or

implementation of corrosion control. The work

must be technical in nature (not sales for example)

and in the corrosion field. Metallurgy, welding

inspection, Non Destructive Testing (NDT) etc,

are not acceptable, except when directly related

to corrosion.Work in responsible charge in corrosion or a

corrosion related field is, work experience as defined

above, which includes a level of responsibility

requiring technical judgement. The applicant

must be in technical control and have technical

responsibility. Work such as design, specification,

and failure analysis etc are considered responsible

work in charge, as opposed to routine testing or

application of corrosion control measures, ie painting

or installing anodes. Affect on ACA MembershipACA accreditation as a Corrosion Technician/

Technologist will have no affect on a member’s

privileges including their right to vote, hold any

office or participate in any associated activity.

Application procedureA completed application form with accompanying

payment and documentation should be sent to the

ACA Certification Scheme, PO Box 112, Kerrimuir

VIC 3129 or faxed to +61 3 9890 7866. Your application will be initially assessed and

you will be contacted if any further information is

required. The ACA will contact your referees and

then forward your application to the Certification

Review Board (which meets periodically - approx

every 3 months) for assessment. You may be

contacted by the ACA or one of the Certification

Review Board members if further information is

needed to properly assess your application. Once

reviewed, you will receive notification by letter as to

the Certification Review Board’s decision.For further information on the Certification Rules,
