靜電火花靈敏度測試儀

L SPARK 是高能量材料靜電敏感度測試儀器系列的最新成員。L SPARK 試驗設備專為測試顆粒床層的裸露高能量材料（煙火成分、一級和二級炸藥以及推進劑）而設計。
L SPARK 還能測試電控引爆裝置 (EED) 對 ESD 能量的抵抗能力。

對於高能量物質的測試，L SPARK 採用了比較法概念-在給定的放電條件下，將被測材料的反應與參考材料以及已知的 ESD 行為進行比較。L SPARK 可以在最短的時間內以最低的成本為使用者提供與被測物質的 ESD 事件相關的風險的基本資訊。這種工作原理不需要對放電進行任何進一步的能量評估或放電診斷。

The L SPARK™ is the newest member of the family of instruments dedicated to the testing of ESD sensitivity of energetic materials. The L SPARK test instrument is designed for the testing of bare energetic materials (pyrotechnic compositions, primary and secondary explosives and propellants) in the granular bed form. The L SPARK is also capable of performing tests of the resistance of ElectroExplosive Devices (EED’s) to ESD energy. 

For testing energetic substances the L SPARK employs the comparative method  concept – the response of the tested material is compared with the reference material along with the known  ESD behavior under the given discharge conditions. The L SPARK provides the user with basic information about the risk  associated with the ESD event of the tested substance within the least time and at minimum costs. This principle of operation  does not require any further energy evaluation or discharge diagnostics of the discharge.

APPLICATIONS
The L SPARK is suitable for applications where only a basic screening of the risk associated with granular energetic materials is required along with impact and friction sensitivity data. The L SPARK’s simple operation and low running costs allow for the testing of a large count of samples in a short period of time with minimal running costs. This feature makes the L SPARK ideally suited for production facilities (e.g. for periodic production tests, or for the quick assessments of new materials/components used in the manufacturing processes). Adoption of the EED´s testing capability makes the L SPARK a good choice for national notified bodies (testing/certification laboratories) or for manufactures of initiating devices such a igniters, squibs or detonators.

ADVANTAGES & FEATURES

• Compact design
• Low running costs
• Suitable for a quick basic screening of the risks associated with all types of granular explosives
• Optional available accessories expand the L SPARK’s capability for the testing of the ESD resistance  of the Electro-Explosive Devices (detonators, igniters, squibs, etc.) according to the EN standardization
• External steel testing chamber (capacity up to 2-gram NEQ)
• The versatility of the spark gap geometry allows for the easy modification of the spark gap geometry
