This document specifies the lighting and procedure for the visual assessment of degraded areas, spots or other defects on or in coatings.

It is not applicable to the visual comparison of colour, which can be assessed using ISO 3668.

This document is one of a series of standards dealing with the sampling and testing of coating materials and their raw materials.

It specifies a method for the determination of the volatile organic compounds (VOC) content and the semi-volatile organic compounds (SVOC) content of coating materials and their raw materials.

This part is applicable for the determination of VOC and SVOC if the expected VOC and/or SVOC content is greater than 0,01 % by mass up to 100% by mass.

If the VOC content is greater than 15 % by mass, the less complicated method given in ISO 11890-1 may be used. If the system contains VOC and SVOC, the VOC result of ISO 11890-1 may be influenced by SVOC. In this case ISO 11890-2 shall be preferred. For VOC content smaller than 0,1 %, the head space method described in ISO 17895 can be used as an alternative. ISO 11890-1 and ISO 17895 cannot be used for the determination of the SVOC content.

NOTE 1 Some ingredients of coating materials and their raw materials can decompose during analysis and cause artificial VOC and SVOC signals. When determining VOC and SVOC for coating materials and their raw materials, these signals are artefacts of the method and should not be taken into account (examples are given in Annex B).

This method assumes that the volatile matter is either water or organic. However, other volatile inorganic compounds can be present and might need to be quantified by another suitable method and allowed for in the calculations. The method defined in this standard is not applicable for determination of water content.

NOTE 2 If organic acids or bases and their corresponding salts are present in the coating material or its raw materials, the amount that is quantified by this method may not be accurate due to a change in the acid or base equilibrium.

This part of ISO 21809 specifies requirements for field joint coating of seamless or welded steel pipes for buried and submerged sections of pipeline transportation systems used in the petroleum, petrochemical and natural gas industries as defined in ISO 13623. This part of ISO 21809 specifies the qualification, application and testing of the corrosion protection coatings applied to steel surfaces left bare after the joining of pipes and fittings (components) by welding.

This part of ISO 21809 defines and codifies in Table 1 the different types of field joint coatings for pipelines.

This part of ISO 21809 does not address requirements for additional mechanical protection, for thermal insulation or for joint infills of concrete weight-coated pipes.

NOTE Field joints of pipes and fittings coated in accordance with this part of ISO 21809 are considered suitable for further protection by means of cathodic protection.
