Dimensions in millimetres Key 1 2-mm-wide scribe line 2 0,mm-wide scribe line Figure 1 — Test panel showing position of each type of scribe line????? Whilst there is no guarantee that a paint system matching one of these examples would provide adequate protection, systems of these types have provided high-durability performance.

If changed, 2340 paint system is subject to re-qualification as agreed between the interested parties. Specifications and definitions for ISO surface profile comparators for the assessment of abrasive blast-cleaned surfaces ISO Table 3 —Typical examples of some protective paint systems and their initial performance Substrate Blast-cleaned carbon steel: Details of the software products used to create this PDF file can be found in the General Info relative to the file; the PDF-creation parameters were optimized for printing.
Close attention needs to be given to the execution of the work. Description of paint system Manufacturer Type of environment Type of substrate Name: Should third-party certification be requested, an independent laboratory shall be agreed on between the interested parties.
Protect the backs and edges of the test panels with an appropriate means of protection fref on between the interested parties. For twin-pack materials, the pot life shall not be exceeded.
Deviations from the over-coating time specified by the paint manufacturer shall be agreed between the interested parties and recorded in the test report. Coating thickness measurements min. The product shall be applied within its shelf life.
The main task of technical committees is to prepare International Standards. The paint manufacturer shall carry out routine batch testing on each batch of paint.
After qualification of a paint system, this fingerprint may be used, if 23040, to ensure that the paint supplied for use matches that subjected to qualification testing.
Examples are ieo in Table 3. Table 3 is not intended to be comprehensive, nor is the intention that it be used as specification guidelines. Assessment after exposure testing h Panel No. Both shall cut completely through the paint coating and into the metal substrate.
Unless otherwise specified, no part of this publication may be reproduced or utilized in any form or by any means, electronic or mechanical, including photocopying and microfilm, without permission in writing from either ISO at the address below or ISO’s member body in the country of the requester. Surface preparation Length, width and thickness: At least the following information shall be shown on the label: The use of the alternative exposure cycle shall be indicated in the test report.
Method for the grading of sio profile of abrasive blast-cleaned steel — Comparator procedure ISO An example of a paint system template is given in Table 2. Many other additional tests could be useful in characterizing more precisely the components of a paint. For reference purposes, some typical examples of protective paint systems which have been used successfully offshore are included in Table 3.
It can also 23040 used for other structures, provided that jso selected paints or protective paint systems comply with this International Standard.
The work of preparing International Standards is normally carried out through ISO technical committees. Pull-off test value before ageing determined in accordance with ISOin MPa 3 3 4 3 3 4 6 8 2 2 a The thickness of the metallic coating is in accordance with ISO hot-dip galvanized or ISO metallized steel and the coating is prepared as given in ISO The actual test or tests to be carried out shall be agreed between the interested freee.
The minimum fee required for a simple identification check if relevant to the product in question are given in Table 1. Such tests are subject to documentation forming part of the paint 203400 quality assurance system and are used to provide the certificate of conformity, if required by the purchaser. End of panel preparation: Methods and requirements are given in Table 5.
Date of report and signatures: This alternative cycle is the same as the standard cycle procedure A but without low-temperature exposure. In the unlikely event that a problem relating to it is found, please inform the Central Secretariat at the address given below. NOTE 2 See 5. If the alternative cycle is used, this shall be indicated vree the test report see Clause 9. Other methods of surface preparation may be used to represent actual field conditions, as agreed between the interested parties.
