And a number of reference substances.
Reference substances for the quality control of medical products.
Work in the field of standards and reference substances continued on from 1972.
The reference substances listed in the table were used in concentrations of 1.
The purity requirements for a chemical reference substance depend upon its intended use.
It is not an assured identification of DEHIP due to lacking reference substance.
CFC-11 has been chosen as reference substance in EDIP as it is in most other contexts.
A label, a specimen of which is shown in the Annex to this Regulation, on which the box corresponding to chemical reference substances has been clearly marked with a tick.
Use gallic acid as reference substance, phosphomolybdium tungstic acid colorimetric method to test tannin content.
For EDIP97 most of the impacts are expressed as quantities of a reference substance which would cause the same size of impact.
On the other hand,chemical reference substances that are to be used in assays should possess a high degree of purity such as 99.5% on the dried or water/solvent free basis.
Council Decision No 73/179/EEC(2) of 18 June 1973, adopting a research programme in the field of reference substances and methods(Community Bureau of Reference); .
The publication of a guide for users of reference substances, the preparation of a data bank on reference substances, and laboratory work.
Council Decision No 73/175/EEC(2) of 18 June 1973, adopting a research programme in the field of standards and reference substances(certified reference substances); .
The EDIP2003 impacts could very well be scaled into emissions of reference substances as was done in EDIP97 but we have chosen to keep the original EDIP2003 units for two reasons.
For environmental impact categories other than toxic impacts, it has been possible andexpedient to express the potential environmental impact of each emission in relation to a reference substance, i.e.
Relief shall extend to any special packaging which is essential to the transportation of chemical reference substances and to any requisite accessories which the consignments may contain.
A chemical reference substance proposed for an identification test does not require meticulous purification since the presence of a small percentage of impurities in the substance often has no noticeable effect on the test.
As regards toxic impacts where there are many different impact mechanisms,it is hard to compare all substances to one reference substance, as the impact mechanisms for the specific substance and the reference substance may differ.
The results oí these analyses were used for reference substances, inter-laboratory comparisons(i.e., the assessment of methods and equipment used in various laboratories), safeguards on fissile materials and in connection with disputes arbitration analyses.
The classification step defines nutrient enrichment as the man-made impact on aquatic or terrestrial systems of nitrogen, N, or phosphorus,P. The total nutrient enrichment potential expresses the emissions as an equivalent emission of the reference substance NO3.
The relief referred to in Article 63c of Regulation(EEC)No 918/83 shall apply only to consignments sent by the'WHO Collaborating Centre for Chemical Reference Substances' in Stockholm(Sweden) to consignees who are authorized by the competent national authorities to receive them duty free.
With regard to the standards and reference substance project, the temporary secretariat, which was set up in April 1972, has continued and expanded the surveys commenced in 1971, prepared a"users' guide to reference substances" and, with the assistance of national experts, defined the priority objectives of a concerted European programme.
For environmental impact categories other than toxic impacts, it has been possible andexpedient to express the potential environmental impact of each emission in relation to a reference substance, i.e. how much more, or less, the specific substance contributes compared to the reference. .
The EDIP2003 impacts could very well be scaled into emissions of reference substances as was done in EDIP97 but we have chosen to keep the original EDIP2003 units for two reasons: they give the user an impression of what is actually expressed by the EDIP2003 impact potentials they emphasize the difference in what is covered by the EDIP97 and EDIP2003 impact potentials and that the two are not immediately comparable.
In EDIP(Hauschild& Wenzel, 1998), the potential depletion of stratospheric ozone is quantified by using ozone depletion potentials(ODP)for substances having the same effect as CFC's. CFC-11 has been chosen as reference substance in EDIP as it is in most other contexts.
The classification step defines nutrient enrichment as the man-made impact on aquatic or terrestrial systems of nitrogen, N, or phosphorus,P. The total nutrient enrichment potential expresses the emissions as an equivalent emission of the reference substance NO3-. The equivalence factor for the total nutrient enrichment equivalent is designated the substance's nutrient enrichment potential.
Assessment of chemical substances in the EDIP model For environmental impact categories other than toxic impacts, it has been possible andexpedient to express the potential environmental impact of each emission in relation to a reference substance, i.e. how much more, or less, the specific substance contributes compared to the reference. .
