Questionnaire Metals in Plastics iis05P03:

Together with the final report of the PT on metals in plastics (iis05P03) a questionnaire was sent to the 66 participants. On 30 November in total 12 participants had returned this questionnaire. This response of 18% is remarkably high.

The answers of the participants show a very high satisfaction and high appreciation of the iis operations: the only negative answers were given about the number of metals investigated. The lack of Mercury in the samples was mentioned several times.

Unfortunately none of the 12 respondents did have a suggestion how to get suitable sample material that would fulfil all needs of the participants.

The answers were in detail:

1. Were the sample amounts that you received sufficient?

   Sufficient 83%, not sufficient 17%
