MIL-STD-810G vs IP67 vs IP68 vs ATA 300:保護ケース認証解説 (2026)
6 つの認証が保護ケース仕様書を支配しています:MIL-STD-810G 落下、IP67/IP68 浸入、ATA 300 機内預入、EU 向け CE / RoHS / REACH。各認証が実際にテストすること、いつ重要か、調達の落とし穴を解説します。
なぜ認証は置き換え可能ではないのか
Every certification answers a specific question about case performance. Conflating them is the most common B2B procurement error.
IP67 answers: will the case keep contents dry in a temporary water immersion? IP68 answers: will the case survive continuous water immersion for 30+ minutes at 1-3 metres depth? MIL-STD-810G answers: will the case survive being dropped, vibrated, and temperature-shocked in field conditions? ATA 300 answers: will the case survive 100 airline baggage handling cycles?
These are different questions. A case can pass IP67 (waterproof) but fail MIL-STD-810G (cracks on drop). A case can pass MIL-STD-810G but fail IP68 (water seeps in under continuous immersion). The buyer must verify the certification that matches the actual use case.
Beware of vague marketing claims. A factory may say "MIL-STD-810G certified" without specifying which lot was tested, what drop height, what temperature range. The only way to verify is to request the lot-specific batch test certificate.
IP67 vs IP68:侵入保護の解説
IP ratings are defined by IEC 60529. The two-digit code after "IP" indicates dust and water resistance. Most protective cases meet IP67 or IP68.
IP67: Protected against temporary immersion in 1 metre of water for 30 minutes. The case must be dust-tight (first digit 6 = dustproof). This covers most B2B field use — outdoor survey, marine deck, helicopter cargo hold, factory floor.
IP68: Protected against continuous immersion in water at 1-3 metres depth for 30+ minutes. Depth and duration specified by the manufacturer. Required for subsea deployment — ROV operations, marine research, diving equipment.
IP rating cost differential: IP67 SKUs are baseline. IP68 SKUs are 10-25% more expensive due to additional sealing and pressure testing. For B2B buyers, IP67 covers 90% of use cases; IP68 is needed only for specific underwater or sustained-pressure applications.
Common procurement trap: "IP-rated" without specifying IP67 or IP68. Always confirm exact rating + batch test certificate.
| IP Rating | Dust | Water Exposure | Typical Use Case | Cost Premium vs IP54 |
|---|---|---|---|---|
| IP54 | Dust-protected (not sealed) | Splashing water | Indoor / light outdoor | Baseline |
| IP65 | Dust-tight | Low-pressure water jets | Outdoor / hose-down | +5-10% |
| IP67 | Dust-tight | Immersion 1m / 30 min | Marine / field work | +10-15% |
| IP68 | Dust-tight | Continuous immersion 1-3m / 30+ min | Subsea / ROV | +25-40% |
MIL-STD-810G:落下と振動の規格
MIL-STD-810G is a US Department of Defense test methodology covering environmental engineering. For protective cases, the relevant sections are drop, vibration, temperature, and humidity.
MIL-STD-810G Method 516.6 — Shock: drop test. The case must survive 26 drops (one per face, edge, corner) from 1.22 metres (48 inches) onto 50mm plywood over concrete. Functional test: contents must remain operational after the drop sequence.
MIL-STD-810G Method 514.6 — Vibration: random vibration simulating transport by truck, aircraft, ship. The case must survive 1 hour per axis at the relevant vibration profile.
MIL-STD-810G Method 501.5 / 502.5 — Temperature: high-temp (49°C for 4 hours) and low-temp (-32°C for 4 hours). Functional test: latches must operate, seals must remain intact.
MIL-STD-810G Method 507.5 — Humidity: 5-day humidity cycle at 95% RH. Functional test: no corrosion, latches remain operational.
For B2B buyers, MIL-STD-810G is the differentiator for defence, aerospace, and outdoor field use. The certificate must specify which methods were tested and the lot number of the tested cases.
ATA 300 カテゴリー I:機内預け入れ手荷物
ATA Specification 300 defines airline-checkable luggage. Category I is the most stringent — the case must survive 100 round trips of airline baggage handling.
ATA 300 Category I tests 100 cycles of: drop, vibration, humidity, and pressure changes simulating aircraft cargo hold. After 100 cycles, the case must still operate (latches, hinges, seals functional).
For B2B buyers in broadcast, photography, surveying, and field service — teams that fly weekly with gear — ATA 300 is the relevant certification. Without it, the case may survive 5-10 trips but fail at trip 30.
ATA 300 is independent of IP rating. A case can be ATA 300 Category I without being IP67. Conversely, IP67 does not imply ATA 300 (the case could be airtight but crack on impact).
For our factory, ATA 300 Category I certification is standard for all trolley-case SKUs. Inspection camera / broadcast SKUs are batch-certified. Confirm at sample stage.
CE / RoHS / REACH:EU コンプライアンス三点セット
For B2B buyers exporting to the EU market, three compliance certifications are mandatory or near-mandatory. Each addresses a different regulatory concern.
CE marking: The product complies with EU safety, health, and environmental requirements. Mandatory for protective cases sold in the EU. Self-declared by the manufacturer for most protective case categories; covers low-voltage directive, EMC directive, and PPE directive (where applicable).
RoHS (Restriction of Hazardous Substances): EU Directive 2011/65/EU restricts lead, mercury, cadmium, hexavalent chromium, PBB, PBDE in electrical and electronic equipment. Plastic cases with metal hardware require RoHS declaration.
REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals): EU regulation covering chemicals used in manufacturing. Plastic cases must declare SVHC (Substances of Very High Concern) below 0.1% w/w threshold.
For B2B buyers, CE / RoHS / REACH are table stakes for EU market access. Verify at sample stage with copy of declaration of conformity. Per-SKU test reports available on request.
知っておく価値のあるその他の認証
Beyond IP / MIL-STD / ATA / CE, three certifications appear frequently on spec documents for B2B procurement.
- FDA compatibility statement: For medical SKUs (defibrillators, AED, pharma transport). Declares the case materials do not interact adversely with the contents. Per-SKU statement available.
- NSN registration support: For defence SKUs. NSN (National Stock Number) assigned by the buyer's defence procurement agency. The factory provides technical data package (TDP) to support buyer's NSN application.
- ATA 300 Category II: Less stringent than Category I — 50 cycles of drop / vibration. For air-freight-not-checkable cases.
- California Prop 65: For US market. Restricts chemicals known to cause cancer / reproductive harm. Most factory-direct cases pass with material declaration.
- UN 38.3: For cases containing or shipping lithium batteries. Mandatory for air freight.
- ISTA 3A: For transport packaging testing. Independent of MIL-STD but sometimes substituted by procurement.
認証の主張を検証する方法
Marketing claims often exceed reality. The four-step verification protects B2B procurement from non-compliant supply.
- Step 1: Request the certificate. Ask for the lot-specific test certificate. Generic factory-wide certificates are weaker than per-shipment-lot certificates.
- Step 2: Check the issuing body. ISO 17025-accredited labs are the most reliable. In-house factory lab testing is acceptable for IP / drop but third-party for defence / aerospace.
- Step 3: Verify test parameters. MIL-STD-810G drop test must specify drop height (typically 1.22m / 48 inches) and number of drops (26). IP67 must specify 1m / 30 min immersion.
- Step 4: Cross-check the lot number. The certificate lot number must match the lot number physically shipped to you. Mismatch = certificate applies to a different shipment.

よくある質問
IP67 と IP68 の違いは何ですか?
IP67 はケースが防塵で、1 メートルの水に 30 分間一時的に浸漬できることを意味します。IP68 はケースが防塵で、1-3 メートルの深さに 30+ 分間連続浸漬できることを意味します(深さはメーカー指定)。ほとんどの B2B 用途(屋外現場作業、海洋デッキ、輸送)では IP67 で十分です。IP68 は水中展開(ROV 運用、海洋研究、潜水機器)にのみ必要です。IP68 SKU は IP67 同等品より 10-25% 高価です。
MIL-STD-810G は実際に何をテストしますか?
MIL-STD-810G は米国国防総省の試験方法論です。保護ケースに関連する 4 つの方法は:方法 516.6 衝撃(コンクリート上の合板に 1.22 メートルから 26 回落下)、方法 514.6 振動(輸送振動プロファイルで軸毎に 1 時間)、方法 501.5/502.5 温度(高温 49°C、低温 -32°C で各 4 時間)、方法 507.5 湿度(95% RH で 5 日間の湿度サイクル)。各試験後、ラッチとシールは機能し続ける必要があります。
ATA 300 カテゴリー I とは何ですか?
ATA 仕様 300 カテゴリー I は機内預入手荷物の標準です。ケースは航空手荷物取り扱い(落下、振動、湿度、圧力変化)の 100 ラウンドトリップに耐える必要があります。100 サイクル後、ケースは動作可能である必要があります(ラッチ、ヒンジ、シール)。ATA 300 カテゴリー I は毎週機材を持って飛行機で移動する放送、写真、測量、現場サービスチームに関連する認証です。ATA 300 なしでは、ケースは 5-10 回の旅行には耐えても 30 回目の旅行で故障します。
EU 輸出に CE / RoHS / REACH は必要ですか?
はい。CE マーキングは EU で販売される保護ケースに必須です。RoHS(EU 指令 2011/65/EU)はプラスチックと金属ハードウェアの有害物質を制限します。REACH(EU 規則)は SVHC 化学物質を 0.1% w/w 未満で宣言します。適合宣言書のコピーでサンプル段階で検証してください。SKU 別試験報告書はリクエストに応じて利用可能。KeXinMaterials はすべての EU 出荷に CE / RoHS / REACH 宣言を提供します。
工場からの認証主張をどのように検証しますか?
4 段階検証:(1) ロット固有の試験証明書を要求する。工場全体の一般証明書は出荷ロットごとの証明書より弱い。(2) 発行機関を確認 — ISO 17025 認定ラボが最も信頼性が高い。(3) 試験パラメータを検証 — MIL-STD-810G 落下は高さ(1.22m / 48 インチ)と落下回数(26)を指定する必要があります。IP67 は 1m / 30 min を指定する必要があります。(4) 証明書のロット番号が出荷されたロットと一致するか確認する。
FDA および NSN 認証はどうですか?
FDA 互換性声明は医療 SKU(除細動器、AED、医薬品輸送)向けです。ケース材料が内容物と悪影響を及ぼさないことを宣言します。SKU 別声明が利用可能。NSF(国家在庫番号)登録サポートは防衛 SKU 向けです。工場は技術データパッケージ(TDP)を提供し、買い手の NSN 申請をサポートします。KeXinMaterials は医療および防衛 B2B 調達の両方をサポートします。
