## Target specs for product 9076

The records carry two levels of target, both labeled as reference targets (the BYK-9076 reference standard), not FOIL measured values.

1. Core target pair (used in the ELN "target-check" of each batch):

• Acid Value (AV): 43.2 (mg OH/g)
• Amine value: 30.1 (mgKOH/g)

These appear as the reference_value in the batch records' critical_parameters (phase = "target-check"), e.g. Batch 25 A [Lab Batc 25 A.pdf, pages 1-2] and Batch 34 B [LBN 34 -B.pdf, pages 1-2], and as the "Conclusion ... aminev - 30.1, av - 43.2" line in the summary table [Old ELN SummaryReport (2).xls, sheet Sheet_JS].

2. Broader reference-product specification ("9076 (Ref)" column), from the R&D review presentation [9076 ppt, slide 24 and slide 27], listing the BYK-9076 reference targets:

• Appearance: Viscous yellowish liquid
• Acid Value: 43.2 (mg OH/g)
• Sap Value: 54 (mgKOH/g)
• Amine value: 30.1 (mgKOH/g)
• OH Value: 65 (mgKOH/g)
• Iodine Value: 9.3 (gm/100g)

All six of these are the reference (BYK-9076) target values, not FOIL measurements. The batches are judged against the same-day BYK-9076 standard run, and the aim in the records is stated as "To develop product equivalent to reference product."

Note: no single document in this drop states an explicit tolerance band (pass/fail limits) around these targets — the records only store the target values themselves.
