GA 419-2003General specifications for cyanoacrylate fuming cabinet for fingerprint development in Forensics (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GA 419-2003 ""502" fingerprinting display cabinet." Compared with GA 419-2003, the main technical changes are as follows.

--- Increased humidity retention function (see 5.2);

--- Added purification function (see 5.2);

--- Added "Humidity sensor should be configured in the smoker cabinet" (see 5.4.2);

--- Added "gas uniformity control in the cabinet" (see 5.4.3);

---Modified standard name (see cover, cover of 2003 edition);

---Modified the surface temperature range of alpha-cyanoacrylate electric heater, the surface temperature of alpha-cyanoacrylate electric heater the degree "50 °C ~ 130 °C" is changed to the range of "50 °C ~ 130 °C" (see 5.4.1, 5.4.1 of the 2003 edition);

---Modified the relative humidity range in the cabinet, and changed the relative humidity range "70%~85%" in the cabinet to "65%~95%" (see 5.4.2, 5.4.2 of the 2003 edition);

--- Removed "fatigue of the cabinet door" (see 5.7 of the 2003 edition).

This standard is proposed by the National Criminal Technology Standardization Technical Committee Criminal Technology Products Subcommittee (SAC/TC179/SC8) and return to the mouth.

This standard was drafted. Ministry of Public Security Material Identification Center, Beijing Brant Police Equipment Co., Ltd.
