Referencing during analysis doesn't work correctly

[Former Member]

Hello EH&S guys,

I encounter a strange problem (or is it working correctly?).

During referencing of an amount stated in the risk assessment, the referenced value is not found.

The characteristic of the referencing value is stated as g/cm3.

It seems that whenever I put for instance g/m3 or any other UoM than stated in the characteristic (CT04) it doesn't work.

Is this normal behaviour? Should the UoM only be limited to the one stated in CT04?

Thanks in advance.

Hi Pascal,

If i understood your question correctly, You cannot change the value for the referenced charecteristic.

Hello Ravindra,

I can change it, but the point is the following:

The reference characteristic (for RHO) contains the UoM mg/m3

But if I state in the property a value with another Uom like g/dm3, and I also add in the amountview of the risk assessment g/dm3,

The reference is not working correctly. It seems that it tries to find a value as stated in mg/m3.

So in our example, the system doesn't find a reference value.

Question is:

Is this normal behaviour? Or is it a bug (couldn't find anything on OSS).

Hi Pascal,

Sorry for the confusion, yes you can overwrite the referenced data. In referencing you cannot change the individual VA instead you can overwrite entire VA type. Also the value which you are going to input must be there in the valueset of the charecteristic.

Hello Ravindra,

Thank you for looking into this. I think I was not really clear in my question. I try to explain it othewhise.

We have a characteristic:

SAP_EHS_1013_005_VALUE

This characteristic has the UoM "g/cm3"

This belongs to the value ass Type SAP_EHS_1013_005 which is used for the property "Density".

In the property tree, I can assign a different UoM than the one stated in the characteristic. For instance:

2 mg/m3

So in our example we would have a threshold value of 2 mg/m3.

In a risk assessment, I enter over in the amount tab "Mass Concentratiön" a value of 0,5 mg/m3.

If I perform the analysis Methods, the system doesn't find the threshold value stated in the property (it sends me back 0 mg/m3).

Is this normal behaviour? Or is this a bug.

Could it be that we are only allowed to use the UoM "g/cm3" since that was the UoM stated in the characteristic. If this is the case, it would not be possible to use other UoM in the property for Density.

Thanks for you advice in this.

Hi Pascal,

You can check by entering the same UOM as given in the charecteristic and analyze if this is causing the issue. Anyways check the below if your case falls under these,

1) If you create an analysis method for an exposure amount of a released measurement project, the system transfers the reference value from the measurement project as well as the measured value. If there is no reference value for the exposure amount, the system issues a message telling you that it could not find a reference value and it continues the processing.

2) The analysis method for the comparison of the measurement reading with the reference value of the risk assessment reads reference values from the assigned specification in the product safety. If the relevant reference values are referenced values from a reference substance (or a reference specification), these are not read.

If I fill in the same UoM in the characteristic, it works.

So I supose it is a bug. I can't imagine that this would be default functionality.
