The W1005-2 is the 2 gram OIML M1 grade calibration weight in the Accuris W1005 calibration-weight family — used for sub-gram calibration of standard / industrial balances (10 mg readability+) where the W1005-1 (1 g) is too small and the W1005-5 (5 g) is too large for the calibration mass-point of interest.
For complete F1 vs M1 grade selection rationale, calibration workflow, and full application profile, see the W1005-1 parent page.

Pack-quantity sizing: Multi-point balance calibration typically uses 5–8 mass values across the balance range (e.g., for a 200 g standard balance: 1 g + 10 g + 50 g + 100 g + 200 g — 5 mass values for full-range calibration).
Application Profile
See the W1005-1 parent page for the full application profile (standard / industrial balance calibration, educational laboratory training, multi-balance facility programs, budget-tier procurement, sub-gram balance verification).
