The purpose and objectives of the task are to develop, improve and promote ISO standards on test procedures and requirements for solar thermal products - and to harmonize at international level certification schemes in order to increase in general the level of quality and at the same avoid the need for re-testing and re-inspection.
The Task will build on the good results and the network established in Task 43.
In Task 43 roadmaps for the need of new test procedures and improvement of test procedures for solar thermal products were made and a new improved ISO standard for collector testing did materialize based on this work. However, there is still a need for improvements in this standard – some climate parameters need adjustment e.g. to make the standard useable also in “extreme” climates – and e.g. new ideas on e.g. accelerated lifetime testing looks very promising and relevant to include. The standard has just been opened for revision to deal with these and other issues. This task will support this work – as well as developing/improving other relevant ISO standards for solar thermal products.
From questionnaires made in Task 43 we learned that in a number of countries, national standards (slightly or very) different from the ISO standards are used. It is the goal that with new improvements of the standards more countries will adapt the ISO standards directly. In this task efforts will be made to try to convince more countries to join the “ISO boat”.
The Global Solar Certification Network (GSCN) has been established in Task 43. Originally the aim was to make ONE globally harmonized certification scheme. But after some discussions it was agreed then – as a first step – to aim at mutual recognition of test and inspection reports. So the existing national and regional certification schemes stay – but the manufacturers can use test and inspection reports made under one certification scheme when he/she applies for certification in other schemes. So the Global Solar Certification Network (GSCN) will now be the framework for this “mutual recognition” concept, the requirements and procedures are in places – and operation is about to start. This task will support the kick-off of the operation of the Global Solar Certification Network.
The draft for the global certification scheme rules will be further elaborated to work as model for new national/regional certification schemes and as inspiration for improvements/harmonization of existing schemes. It will be considered if an ISO Technical Report for solar certification schemes should be proposed and elaborated.
The main activities in the Task 57 are grouped in the following subtasks:
- Subtask A: Kick-off of operation of Global Solar Certification Network (GSCN)
- Subtask B: Improvement of test procedures – support and input to ISO
- Subtask C: Promotion and capacity building with respect to ISO standards and state-of-the-art certification schemes
