When it comes to testing HEPA and ULPA filters, two major standards are widely used:
で 1822 そして ISO 29463.
Although they are closely related, there are important differences in their structure, 応用, and global usage.
This guide explains the key differences to help you understand which standard to use—and why it matters.
1. ENの概要 1822 およびISO 29463
で 1822
- European standard
- Focused on HEPA/ULPA filter testing
- Widely used in Europe and many international projects
ISO 29463
- International standard (based on EN 1822)
- Developed to harmonize global testing methods
- Increasingly adopted worldwide
👉 In simple terms:
ISO 29463 = international version of EN 1822 (with some extensions)
2. Structural Differences
で 1822 構造
で 1822 is typically divided into 5 部品:
- 分類, performance testing
- Aerosol production and measurement
- Flat sheet media testing
- Leak test (スキャンテスト)
- Filter element testing
ISO 29463 構造
ISO 29463 expands this into multiple parts with more detailed guidance, 含む:
- Additional definitions
- Extended testing procedures
- Global harmonization
👉 ISO 29463 is more comprehensive and standardized internationally
3. 分類システム
どちらの規格も MPPS での効率に基づいてフィルタを分類しています:
| Class Type | で 1822 | ISO 29463 |
|---|---|---|
| HEPA | H13 ~ H14 | Same |
| 怒り | U15–U17 | Same |
👉 Classification values are essentially aligned
4. Testing Method Comparison
Similarities
Both standards include:
✔ MPPS determination
✔ Efficiency testing
✔ Leak (scan) テスト
Differences
| 側面 | で 1822 | ISO 29463 |
|---|---|---|
| 範囲 | ヨーロッパを中心とした | Global |
| Detail level | Moderate | More detailed |
| Standardization | Regional | 国際的 |
👉実践中:
Test principles are the same, but ISO 29463 is more standardized globally
5. リークテスト (スキャンテスト): No Real Difference
The most critical test in both standards is the スキャンテスト.
- Detects local leaks in filters
- Ensures uniform performance
- Required for HEPA/ULPA validation
👉 Equipment requirements are essentially the same for both standards
6. Which Standard Should You Use?
Choose EN 1822 if:
- Your market is Europe
- Your clients specify EN standards
- You work with established HEPA production lines
Choose ISO 29463 if:
- You sell globally
- You need international compliance
- Your clients require ISO certification
👉 Many manufacturers now test according to both standards
7. Practical Challenges in Testing
Regardless of the standard, common challenges include:
- Detecting micro-leaks
- Maintaining stable aerosol concentration
- Achieving consistent scanning speed
- Avoiding false positives
👉 These challenges directly impact test accuracy
8. 推奨されるテストソリューション
To meet both EN 1822 およびISO 29463 要件, a reliable scanning system is essential.
の SC-L8023 Scanning Filter Tester from SCPUR is designed for:
- 高感度の漏れ検出
- Precise scanning control
- 安定した再現性のあるパフォーマンス
👉 Suitable for both EN 1822 およびISO 29463 テスト
9. 結論
で 1822 およびISO 29463 are closely related standards for HEPA and ULPA filter testing.
- で 1822 → widely used in Europe
- ISO 29463 → global standard based on EN 1822
👉 In most cases, the testing methods are similar, and the choice depends on your market requirements.
