Ruhr joint tester CSI-Z001 Shanghai Chengsi related standards and requirements

The first element of the Ruhr joint tester Luer joint is the cone fit, the taper is 6%.


In order to ensure a strong connection, the Luer joint also derives a second element - thread.


Threaded, called locking luer joint.


In practice, most are locking luer fittings
.

The Ruhr joint was invented by the Germans, and the inventor was called Luer
.

Implementation standard: The international standard for Ruhr fittings is the ISO standard (ISO means the International Committee for Standardization
).

First the ISO 594 series, then the transition to the ISO 80369 series
.

The ISO 594 standard was published in its first edition
in 1967.

The 2nd edition was divided into two, with Part 1 General Requirements in 1986 and Part 2 Locking Joints
in 1991.

ISO 80369 is a larger collection than the Ruhr fitting, of which the part 7 is ISO 80369.
7
.

ISO 80369.
7 was published in its first edition in 2016 and its 2nd edition
in 2021.

In terms of domestic standards, the earliest is the GB 1962 series, and the next step will be to transition to the YY 0916 series
.

GB 1962 was published in the first edition in 1980, revised and replaced in 1986 and 1995, and the 4th edition was published in 2001
.

Since the 4th edition, the 1962 standard has also been divided into two, and the first part is the general requirements, corresponding to ISO 594-1; Part 2 is to lock the Luer fitting, which corresponds to
ISO 594-2.

The first 3 editions are mandatory standards and the 4th edition is recommended
.

The YY 0916 standard corresponds to ISO 80369 and consists of 7 parts
.

Part 1 is the General Requirements, introduced in 2014; Part 7 corresponds to ISO 80369.
7 and has not yet been introduced
.

The Ruhr joint tester can test the leakage, air leakage, separation force, unscrew torque, easy assembly, anti-slip yarn, stress cracking, positive pressure and negative pressure of the conical joints (locked and non-locking) of medical devices (luer) such as syringes, injection needles, and infusion sets, blood transfusions, infusion needles, catheters, anesthesia filters and other medical device (Luer) cone joints (locked and non-locked
).
