ATA 300 vs MIL-STD-810G:B2B 保護ケース仕様比較
ATA 300 と MIL-STD-810G は 2 大支配的な B2B 保護ケース仕様。ATA 300 は航空重視(落下 + 振動 + 雨);MIL-STD-810G は軍事/産業(落下 + 振動 + 湿度 + 温度衝撃)。
ATA 300 仕様概要
ATA 300 (Air Transport Association Specification 300) is the airline-checkable case standard. Three categories: Cat 1 (100+ trips), Cat 2 (50 trips), Cat 3 (10 trips). Required for production crews, broadcast, military deployment.
Scope: airline check + handling cycles + drop + vibration + rain + impact. Designed for wheeled trolley cases checked into airline cargo. Pelican Airlines / SKB iSeries are the most common ATA 300 certified cases.
Category 1 (100+ trips): premium. 100+ airline trips. 100+ handling cycles. Drop, vibration, rain, impact. Standard for frequent flying production crews.
Category 2 (50 trips): mid-range. 50 trips. Lower handling cycle. Cost 10-20% less than Cat 1.
Category 3 (10 trips): budget. 10 trips minimum. Entry-level ATA 300 compliance. Cost 20-30% less than Cat 1.
Test requirements: drop test 12 edges / 8 corners / 6 faces (multiple heights), vibration test (truck transport simulation), rain test (sprayed water), impact test (50G). Test report required for certification.
MIL-STD-810G 仕様概要
MIL-STD-810G (US Military Standard 810G, replaced by 810H in 2019) is the military / industrial environmental testing standard. 30+ test methods covering drop, vibration, humidity, temperature, fungus, salt fog, altitude, acceleration.
Scope: military / industrial / aerospace / marine / field deployment. Designed for equipment exposed to extreme environments. Standard for US military NSN procurement.
Test methods (30+): drop (method 516.6, 26 drops at multiple angles), vibration (method 514.6, truck transport simulation), humidity (method 507.5, 95% RH for 10 days), temperature shock (method 503.5, -40C to +70C), fungus (method 508.6), salt fog (method 509.5), altitude (method 500.5), acceleration (method 513.6).
MIL-STD-810G vs MIL-STD-810H: 810H is the 2019 revision. Adds ballistic shock, freeze-thaw, longer humidity cycles. 810G is still accepted but 810H is preferred for new contracts.
Test cost: USD 5,000-20,000 per case model (full range of 30+ methods). Lower for partial compliance (5-10 methods typically used).
Test report required for certification. Certificate + detailed test data per method. Validated by US DoD accredited lab.
並列比較
Both specs cover drop + vibration. Differences emerge in humidity, temperature, salt fog, and certification scope.
Drop test: ATA 300 = 12 edges + 8 corners + 6 faces. MIL-STD-810G = 26 drops at multiple angles (more comprehensive). ATA 300 drop is single-height; MIL-STD-810G tests multiple heights.
Vibration test: both use truck transport simulation. MIL-STD-810G has additional random vibration profiles.
Humidity: MIL-STD-810G has 10-day 95% RH humidity test. ATA 300 has no humidity test. For tropical / marine use, MIL-STD-810G is required.
Temperature shock: MIL-STD-810G has -40C to +70C thermal shock. ATA 300 has no temperature spec. For arctic / desert / aerospace, MIL-STD-810G is required.
Rain: ATA 300 has rain test. MIL-STD-810G has separate water immersion test (method 512.5). For airline check, ATA 300 rain test is adequate. For underwater / marine, MIL-STD-810G is required.
Salt fog: MIL-STD-810G has salt fog (method 509.5). ATA 300 has no salt fog. For marine / coastal use, MIL-STD-810G is required.
Certification scope: ATA 300 = self-certification by manufacturer with test report. MIL-STD-810G = third-party DoD lab certification. MIL-STD-810G is more rigorous.
コスト差とテスト費用
ATA 300 certification is cheaper than MIL-STD-810G. Cost difference affects case pricing.
ATA 300 test cost: USD 2,000-5,000 per case model. Self-certification by factory + test report. Lead time 1-2 weeks.
MIL-STD-810G test cost: USD 5,000-20,000 per case model (full range of 30+ methods). Lower for partial (5-10 methods typically used): USD 3,000-8,000. Lead time 4-12 weeks.
ATA 300 cases are typically 10-30% cheaper than MIL-STD-810G cases due to lower test cost and shorter lead time.
For B2B buyers: ATA 300 is cost-effective for airline-checked production crews. MIL-STD-810G is required for military / extreme environment / aerospace / marine.
B2B ユースケース推奨
Different use cases favor different specs. Below is the 2026 B2B procurement recommendation.
Photography / broadcast (frequent airline check, USD 5,000-50,000 gear): ATA 300 Cat 1. Pelican Airlines 1615 / Storm iM2620 are standard. Cost-effective for 50+ trips/year.
Military / tactical (NSN procurement, USD 1,000-50,000 gear): MIL-STD-810G. Required by US DoD for NSN. Berry Amendment compliant for US military contracts.
Industrial / measurement (5+ kg instrument, occasional transit): MIL-STD-810G drop + vibration. Humidity if tropical deployment. Lower test cost if not full MIL-STD-810G compliance needed.
Marine / coastal / offshore: MIL-STD-810G drop + IP68 + salt fog. Required for offshore / naval use. ATA 300 not adequate.
Aerospace / aviation: MIL-STD-810G + AS9100 quality. Required for aerospace industry. AS9100 is the aerospace quality management standard.
Cold chain / pharma: MIL-STD-810G humidity + temperature shock. Required for pharma cold chain. ATA 300 not adequate.
一般的な組み合わせ + コスト最適化
Many B2B buyers combine specs to optimize cost. Below are common combinations.
ATA 300 Cat 1 + IP67: standard for production crew cases. Cost USD 200-500 per case + test USD 2,000-5,000. Total USD 100K-300K for 100 cases.
MIL-STD-810G (drop + vibration only) + IP65: budget military / industrial. Test cost USD 3,000-5,000. Lower than full MIL-STD-810G.
MIL-STD-810G (drop + vibration + temperature) + IP67: arctic / aerospace. Test cost USD 5,000-8,000.
MIL-STD-810G (full) + IP68 + salt fog + humidity: military NSN procurement. Test cost USD 15,000-25,000. Most rigorous combination.
ATA 300 + IP65 + drop only: budget airline check. Lowest cost. Test USD 1,500-3,000.
