Part 8:

Dev elopment of specifications for new w ork and maintenance

T his part of ISO 12 4 deals with the development of spe ific tions for cor osion prote tion of

ste l structure , using prote tive paint systems It relate to new work and maintenanc in the

work shop or on site and is also appl c ble to the cor osion prote tion of individual components

T his part of ISO 12 4 conc rns the cor osion protection of ste l structures ex os d to different

cor osion stre s s by environments such a indoors, open-air and immersion in water or burial in

soi , a w el a spe ial stre s s, for example due to medium or high temperature T he ne d for

different durabi ity range is considered

Ste l surfac s that have been hot dip-galvanized, metal-sprayed, zinc-ele troplated or

sherardized, and previously painted ste l sur a e , are also covered by this part of ISO 12 44

In annex B, referenc are s for a s s ing the qual ty of the cor osion prote tion work and the

performanc of the prote tive paint systems us d are de lt with A nnexe C and D provide

detai ed flow charts f or planning new work and maintenanc , which should be taken into a count

when w riting a specific tion

If extreme cor osion stre s s or high temperatures oc ur, or the prote tive paint systems are to

be us d on other substrate such as non-fer ous metals or concrete, the spe ific tions wi have

to tak e this into ac ount T his part of ISO 1294 may also be us d a a guide in such c s s

For the purpos s of this part of ISO 12 44, the fol owing definitions apply in addition to thos

given in ISO 12 44-1

and which wi therefore require a spe ific protective paint system spe ific tion

NOTE F r e ample, a storag tan w il hav e more than o e co stitu nt eleme t, a it comprises internal

and e ternal surfaces, an p s ibly also su p rt ste lw ork

3.2 dry f ilm thick nes (DFT ): T he thickne s of a coating remaining on the surfac when the

coating ha hardened

NOTE F r d tai s, se ISO 12 4 -5:19 8, su clause 5.4

spe ific tions (3.8.1 to 3.8.4)

3.5 maintenance: T he sum of al me sure , as covered by ISO 12 4 , which ensure that the

function of the protection of the ste l structure against cor osion is maintained

NOTE Mainte ance inclu es b t is n t lmite to paint w ork Such paint w ork c n b patch painting (re air

of d gradate sp ts/area of th coating system), patch paintin fol ow ed b ov rpaintin of th structure,

or total re aintin

3.6 nominal dry f ilm thicknes (NDFT): The dry film thick ne s spe ified for ea h coat or for the

whole paint system to a hieve the required durabi ity

NOTE F r d tai s se ISO 12 4 -5:19 8, su clause 5.4

3.7 project: T he whole of the work for which the spe ific tion (3.8) is being developed T he

proje t may include one or more structure

3.8 specif ic tion: A te hnic l document de cribing al the requirements that are to be obs rved

when a ste l structure is to be prote ted against cor osion by using protective paint systems

Such a document consists of s veral individual spe ific tions - project spe ific tion, prote tive

paint system spe ific tion, paint work specific tion, inspe tion and a s s ment spe ific tion - a

defined in 3.8.1 to 3.8.4

3.8.1 project specif ic tion: T he spe if ic tion that de cribe the project and the requirements

relating specific l y to it

NOTE Th specifi r of a project sp cific tio may, for e ample, b th ow ner of th structure to b

protecte or th prime co tra tor

Trang 11

3.8.2 protectiv e paint sy stem specif ic tion: T he spe ific tion that de cribe the preparation of

the surfac of the structure and the prote tive paint system(s) f or the structure, in conformity

w ith the proje t specific tion (3.8.1)

NOTE Th sp cifi r of a protectiv paint system sp cific tio may, for e ample, be a paint man facturer

3.8.3 paint w ork specif ic tion: T he specif ic tion that de cribe the way the paint work is to be

c r ied out, in conformity with the proje t specific tion (3.8.1) and the prote tive paint system

spe ific tion (3.8.2) a w el a w ith the inspection and a s s ment specific tion (3.8.4)

NOTE Th sp cifi r of a paint w ork sp cific tio may, for e ample, b a paint ap lc tion compan

3.8.4 inspection and a ses me t specif ic tion: T he spe if ic tion that de cribe how inspe tion

and as e sment are to be c r ied out

3.9 specif ier: A ny ne re ponsible for the development of a spe ific tion

3.10 st ucture: A ste l construction (for example a bridge, a factory bui ding, a storage tank or

an off shore construction) consisting of more than one constituent element (3.1) There may be

one or more structure in any given proje t (3.7)

4 How to dev elop a specif ic tion f or new w ork or maintenance

It is re ommended that the spe ifier considers the information given in claus 5, and e tabl she

which spe ific tion(s) apply/appl e to the proje t or constituent element to be prote ted Then,

the spe ifier should chec in the respe tive table, item by item, which of the items l sted are to be

tak en into a count in the spe ific tion T he various items are supported by detai ed information

given in the "Remark s" column in tables 1 to 4, and in the annexe

W hen writing a spe ific tion f or new work or maintenanc , it is important to chos the most

suitable prote tive paint system T o achieve this al relevant parameters shal be tak en into

consideration, for example:

- required durabi ty;

- environmental conditions and spe ial stre s s;

- sur a e preparation;

- different generic ty es of paint;

- number and ty e of coats [priming coat(s) intermediate coat(s) and top coat(s) ;

- methods of appl c tion and appl c tion requirements;

- plac of appl c tion (shop or site)

- s affolding requirements;

- requirements regarding (future) maintenanc (if any)

- he lth and s fety requirements;

- environmental prote tion requirements

T he e parameters are de cribed in detai in ISO 12 4 -1 to ISO 1294 -7 In this part of ISO 12 4 ,

only such information is given w hich is considered to be particularly important to the spe ifier

In the drafting of a specific tion for maintenanc work on a structure or constituent element, a

decision has to be tak en betwe n

- complete renew al and

- partial removal of the protective paint system inv lved

Trang 12

W hen complete renewal ha be n de ided, the spe ific tion should preferably be developed in

a cordanc w ith a spe ific tion for new work , e.g using the form given in annex G

A t an e rly stage in the drafting of a proje t spe ific tion, a final de ision w il have to be tak en by

the specifier on es ential planning parameters, such a prote tion of sl p-resistant conne tions

using high- ensi e bolts, the inside surfac s of hol ow s ctions and other hidden ste l surfac s

(s e ISO 12 4 -3 for detai s of de ign)

Exclusions, i e items not to be painted, shal be indic ted in the spe ific tion(s)

T he choic of prote tive paint systems shal be ba ed on pra tic l experienc and/or the re ults

of laboratory performanc te ts, particularly when new coating te hnology is inv lved The

protective paint systems shal be te ted for compatibi ty with existing coatings on previously

coated sur a e

T he spe ifier shal further tak e into a count regulations and/or requirements relating to

environmental protection, he lth and s fety, and work ing conditions in the shop or on site

Be aus national requirements conc rning he lth and s f ety at work , pol ution control etc vary

signific ntly, it may not be pos ible to include detai ed information covering such requirements

in a spe ific tion Howev er, the spe ific tion shal draw at ention to the ne d to comply with

cur ent loc l, regional, national and international legislation and regulations
