fire protection material shall be inspected to ensure

that the original packaging is not damaged.

For piping, fittings and flanges, are these items

lifted, moved and stored on site prior to use inaccordance with manufacturers specifications for

short and long term storage

Is there a control manifest or warehousing control

for receiving, issue and return of materials

Sect 5.3: System design

documentation

Does WENCO provide red line / as-built mark-up’sfor inclusion in client design dossiers

Sect 5.4:

All pipe, fittings and relateditems shall be installed byqualified GRP pipe fittersand thereafter approved bya qualified GRP pipinginspector. GRP pipe fittersand GRP piping inspectorsshall be qualified accordingto the minimumrequirements detailed in Annex D.

Installer requirements Are all Bonders and Pipe Fitters:1. Verified as having the requisite years of

experience through reference checks prior

to mobilisation

2. Past training certification checked as valid

3. Qualified or re-qualified by a WENCO

trainer according to BS EN ISO 14692-4:2002 Annex D, Qualification of pipe

fitter, supervisor and inspector (asappropriate)

4. Are training records maintained and are

they auditable

5.

identifying training cards / certificates

Are all tradesman Bonders and Pipe Fitters

adequately supervised and monitored by:

Site Manager

Qualified Trainer

Qualified Supervisor Qualified Foreman

Qualified QC Inspector

Sect 5.5:

work commences.

installed so that they are stress-free; therefore:

a) bending of pipes to achieve changes in

direction, or forcing misaligned flangestogether by over-torquing bolts is not

permitted;

b) the manufacturer’s recommendations forbolt-torquing sequence, torque increments

and maximum bolt torque shall be followed.

Are there deviations to installation methods being

employed and are these recorded and traceable to

the installed equipment

Is there a Technical Query process that highlights

deviations and changes and does it provide client

instructions / responses

Sect 5.5.6.2: 5.5.6.2 Quality controlof adhesive and

laminated jointings

If so required by the principal, the followingrequirements shall be included for installation.

a) The frequency of testing shall be agreed

between the installer and the principal.b) The adhesive or resin used shall be in

accordance with the manufacturer's

recommendation and its degree of cure

shall be determined according to therequirements given in 6.8.2 of ISO 14692-

2:2002.

c) The adhesive or resin shall be applied at atemperature of at least 23 °C and a

relative humidity of less than 75 %.

For epoxy-based products, the glass transition

temperature T g of the cured adhesive or resin shall

not be less than 95 % of the minimum value

quoted by the manufacturer for the adhesive orresin system.

For polyester- and vinyl ester-based products, the

residual styrene monomer content for joints shall

be determined by measuring on a dummy jointmade up prior to starting the jointing work. The





of 8

styrene content shall be less than or equal to 2 %

(mass fraction) of the resin content.

The Barcol hardness shall be measured on all

laminated joints. It is recommended that a

minimum of ten readings be taken on each sample.The two highest and two lowest readings may be

discarded, with the remaining six to be used to

calculate an average reading which shall not be

less than 90% of the minimum value measured onthe baseline component. If an alternative method

has been used to determine the baseline for degree

of cure, then the acceptance criteria for qualitycontrol shall be agreed with the principal.

5.5.8 Quality programme for

installation

The contractor shall maintain a high level of

inspection to ensure compliance with all

requirements of this part

of ISO 14692, and shall have a quality managementsystem.

The contractor shall designate one individual,

experienced in all aspects of GRP piping field

fabrication, to be responsible for quality control

throughout the installation of the GRP pipingsystem. Quality control shall be based on the

implementation of:

records of adhesive and lamination

jointing procedure qualification,

requirements by the principal forinspection of all types of joints used,

inspection register for all types of jointsused,

inspection of finished fabricated

pipework for compliance with design

drawings, within tolerances as detailed in5.5.4.3.

For quality assurance and quality control during

the installation phase, the principal shall have the

right to inspect the ongoing work as well asinspect the contractor’s quality control routines.

Each connection shall be permanently marked for

identification purposes. A log book containing keyvalues relevant for the bonding process shall be

maintained.

The key values are the following:a) date;

b) temperature and relative humidity;

c) connection identification number;d)

electrical continuity and resistance to

earth if appropriate;

e)

curing temperature and time;

f)

signature of pipe fitter and inspector;

g)

bolt torque.Sect 5.6: System testing Does WECO have a Hydrostatic test procedure and
