# Commission Directive 2004/73/EC of 29 April 2004 adapting to technical progress for the twenty-ninth time Council Directive 67/548/EEC on the approximation of the laws, regulations and administrative provisions relating to the classification, packaging and labelling of dangerous substances (Text with EEA relevance), Division: TEST REPORT

Extent: E+W+S+N.I.

The test report must include the following information:
Complete identification of the soil used including:
geographical reference of the site (latitude, longitude);
information on the history of the site (i.e. vegetation cover, treatments with crop protection products, treatments with fertilisers, accidental contamination, etc.)
use pattern (e.g. agricultural soil, forest, etc.);
depth of sampling (cm);
sand/silt/clay content (% dry weight);
pH (in water);
organic carbon content (% dry weight);
nitrogen content (% dry weight);
cation exchange capacity (mmol/kg);
initial microbial biomass in terms of percentage of the total organic carbon;
reference of the methods used for the determination of each parameter;
all information relating to the collection and storage of soil samples;
details of pre-incubation of soil if any.
Test substance:
physical nature and, where relevant, physical-chemical properties;
chemical identification data, where relevant, including structural formula, purity (i.e. for crop protection products the percentage of active ingredient), nitrogen content.
Test conditions:
details of the amendment of soil with organic substrate;
number of concentrations of test chemical used and, where appropriate, justification of the selected concentrations;
details of the application of test substance to soil;
incubation temperature;
soil moisture content at the beginning and during the test;
method of soil incubation used (i.e. as bulk or as a series of individual subsamples);
number of replicates;
sampling times.
Results:
method and equipment used for measurement of respiration rates;
tabulated data including individual and mean values for quantities of carbon dioxide or oxygen;
variation between the replicates in treated and control samples;
explanations of corrections made in the calculations, if relevant;
the percent variation of glucose-induced respiration rates at each sampling time or, if appropriate, the EC50 with 95 per cent confidence limit, other ECx (i.e. EC25 or EC10) with confidence intervals, and a graph of the dose-response curve;
statistical treatment of results, where appropriate;
all information and observations helpful for the interpretation of the results.
