    v5 v6  
    77For example, if the software did not independently detect mutagenicity, carcinogenicity or reprotoxicity then it can be accepted as not known by the introducer to be so. This is because the user can add such hazards and the software would thereby "know" such a characteristic exists.
    88
     9The new Reported category of 10kg or less does not need to tick the boxes ticked for normal Reported category.
    910
    10 '''Program flow'''
     11In particular, health and environment categorisation volumes are irrelevant - they are less than 10kg. Exposure and release factors are also irrelevant for such a small quantity.
    1112
    12 The new rules start with the Reported category.
    1313
    14 At that point, if the total volume is <= 10kg, auto-categorisation as REPORTED10KG should commence.
     14'''Program redesign'''
    1515
    16     We need to examine precisely where to interrupt categorisation processing to call each of the methods mentioned below. Currently, the process simultaneously assigns hazards based on reference lists and/or chemical characteristics and writes the particular notes titled "Health (or Environment) info required for AICIS ..." for that portion of the categorisation. We may need to start that process with the total volume and keep parallel categorisation streams updated until one knocks out the other.
     16We have a set_category() method which first eliminates excluded, prohibited and other possible categorisations including Listed set according to circumstances established by the user and then tests for risk to determine Exempted, Reported or Assessed.
    1717
    18     User initiation by selecting REPORTED10KG would be incompatible with current program flow which must calculate the category.
     18If the risk is actually very-low, we should ignore REPORTED10KG and categorise as Exempted. The reasoning is that REPORTED10KG is then unnecessary and if used AICIS would need to be notified in future if volumes increased beyond 10kg.
    1919
    20     There are category user-selections of Commercial evaluation and Exceptional circumstances which are respected, but they bypass the categorisation software.
     20If the chemical fails the set of rules for <= 10kg then it will be either Reported or Assessed.
     21
     22This puts the new hierarchy of categories as:
     23
     241. Exempted - very low risk
     252. Reported <= 10kg - low risk
     263. Reported - low risk
     274. Assessed - medium to high risk
     28
     29When all is working correctly and unit tests are passing this ticket will be closed.
