Hi Brad,

Thanks for your post.  You're right - ESdat 5 has some great new features to help users manage complex environmental standards.

Depth dependent environmental standards will apply when the chemistry sample depth falls within the Conditional_Depth_From/To interval of an Environmental Standard.

Conditional matrix environmental standards apply when the Env_Stds_Conditional_Matrix_Type field against the chemistry sample matches the Env_Stds_Conditional_Matrix_Type field of an Environmental Standard.

Standards conditional upon another chemical range will only apply when the reference chemical (such as pH or hardness) falls within a specific range (Conditional_ChemCode1/2_Value_Min/Max). Up to 2 conditional (reference) chemicals can be applied.

A True/False value in the Applies_To_Total_Result / Applies_To_Filter_Result fields control application of a standard to filtered/non-filtered results.

I trust this helps.

All the best,

Tom

Hi Brad,

We don't have an annotated example immediately available - that's a useful suggestion.

However you'll find additional detail at the link below:
