What is the Law on Promoting Green Purchasing?
The Law on Promoting Green Purchasing
The Law on Promoting Green Purchasing, more properly the “Law on Promotion of Purchasing of Environmentally Friendly Products by the National and Other Governments,” was passed May 24, 2000 and came into effect April 1, 2001. The law requires all local public bodies, business operators, citizens and manufacturers affiliated with national, prefectural and municipal governments and their agencies to move toward green purchasing, to help create a society capable of sustainable development.
*Green purchasing is the practice of considering carefully whether you really need the product or service you are purchasing, and considering its environmental impact along with the usual criteria of price, quality, convenience and design. Purchasers are encouraged to seek out products with the least environmental impact (such as Eco Mark products).
Green Purchasing Criteria
I-O DATA product categories that conform to the criteria of the Law on Promoting Green Purchasing are as follows.
Hard disk drives
Evaluation Criteria
The energy consumption efficiency shall not exceed the Standard Energy Consumption ate obtained by the formula of applicable category in Table
Note:
1.Magnetic disc drive units that meet any of the following criteria will not be regarded as a magnetic disc drive unit under consideration in the evaluation criteria in this section.
- Memory less than 1 gigabyte.
- Disc diameter less than 40 mm.
- Maximum data transfer speed exceeds 70 gigabytes/second.
| Category | Formula for calculating standard energy consumption efficiency | |
|---|---|---|
| Type of magnetic disk unit | Shape and performance of magnetic disk unit | |
| Single Unit disk | Disk size exceeding 75mm; 1disk | E = exp(2.98 x ln(N) – 28.6) |
| Disk size exceeding 75mm; 2 or 3 disks | E = exp(2.98 x ln(N) – 29.3) | |
| Disk size exceeding 75mm; 4 or more disks | E = exp(2.98 x ln(N) – 29.5) | |
| Disk size exceeding 50mm, and no more than 75mm; 1 disk | E = exp(2.98 x ln(N) – 28.6) | |
| Disk size exceeding 50mm, and no more than 75mm; 2 or 3 disks | E = exp(2.98 x ln(N) – 29.4) | |
| Disk size exceeding 50mm, and no more than 75 mm: 4 or more disks | E = exp(2.98 x ln(N) – 29.8) | |
| Disk size exceeding 40mm, and no more than 50mm; 1 disk | E = exp(2.98 x ln(N) – 27.2) | |
| Disk size exceeding 40mm, and no more than 50mm; 2 or more disks | E = exp(2.98 x ln(N) – 28.8) | |
| Sub-system | E = exp(2.00 x ln(N) – 19.7) | |
Note:
- In the formula for calculating standard energy consumption efficiency, “N” representsvolutions per minute of magnetic disk (unit: rpm).
- “ln” represents a logarithm where the base is “e”.
Displays
Evaluation Criteria
- (1) Shall meet the standard of applicable category in Table.
- (2) Is capable of automatically resuming to a useable mode when task is resumed.
- (3) Specified chemical substances (lead, mercury, cadmium, chromium (VI) compound, PBB, PBDE) should not exceed the standard content rate. Content information of those chemical substances can be easily obtained on its website, etc.
Table : Standard Energy Consumption at each mode for Monitors
| Energy consumption at on mode | Energy consumption at sleep mode | Energy consumption at off mode | |
|---|---|---|---|
| Diagonal Screen Size : < 30 inches Resolution: ≤ 1.1 MP | ≤ 6 x MP +0.05 x A +3 | ≤ 2W | ≤ 1W |
| Diagonal Screen Size: < 30 inches Resolution: > 1.1 MP | ≤ 9 x MP +0.05 x A +3 | ||
| Diagonal Screen Size: 30–60 inches All Resolutions | ≤ 0.27 x A +8 |
Note: MP is the number of megapixels in decimal form. A is the viewable screen area (in square inches).
