4 Materials
4.1 The tube must be made of a material that allows the contents of the container to be clearly seen by visual inspection.
It is recommended that the inner surface of glass tubes intended for specimens to be used in blood coagulation studies should not cause contact activation (see ).
4.2 If a container is specifically designed to test a particular substance, the maximum level of contamination of the interior of the container with that substance and the analytical method used should be specified by the manufacturer in the accompanying information, on the label or on the packaging (see also 10.4).
In the case of using a sample for the study of certain metals and other well-defined substances, the formula of the composition of the plug material should be such that there is no interference that affects the results.
NOTE For highly sensitive methods (e.g. using fluorometry) or for infrequently used tests, there may not be an agreed interference limit. In such cases, the user is advised to consult the manufacturer.
4.3 Containers containing microorganism-preserving additives, such as trisodium citrate or citrate-phosphate-adenine-dextrose solution, should be inspected to prevent microbial contamination of the additive and the interior of the container.
NOTE It is the responsibility of the manufacturer to validate the process. This International Standard does not specify a validation procedure, but a related standard is under development.
4.4 The container must be free from foreign objects during visual inspection.
5 Capacity
5.1 When tested in accordance with the methods given in Annexes A and B, the volume of water added to or drawn from the burette shall be within ±10% of the rated capacity.
5.2 In order to carry out the tests in accordance with the methods given in Annexes A and B, containers of additives shall be provided with sufficient free space to ensure adequate mixing by mechanical and manual means. The minimum headspace to allow adequate mixing should be as given in Table 1. It must be assumed that the headspace available for mixing the contents of the container is limited by the bottom surface of the stopper and the meniscus of the liquid.
Table 1 - Values for the minimum free space to allow adequate mixing
Nominal container capacity, ml | Minimum free space value |

NOTE It is the manufacturer's responsibility to verify the effectiveness of the process. This International Standard does not specify a verification process procedure, but a standard for control methods and sterilization confirmation processes is being developed. In the absence of national regulation, refer to the current European Pharmacopoeia, the current USP or the current British Pharmacopoeia.
8.2 Sterility is required when blood is drawn in direct contact between the inside of the container and the patient's bloodstream.
9 Additives
9.1 The specified nominal amount of additive should be within the limits specified in Annex E.
NOTE With one exception (see 9.2), test methods are not specified.
In the presence of sodium, potassium or lithium in the additive, it is recommended to use flame photometry. It is important that the accuracy of the test is within the error limits given in Annex E. If the test method is non-specific, such as flame photometry for sodium and potassium salts of ethylenediaminetetraacetic acid, an identification test is recommended.
9.2 The volume of the liquid additive in the container must be determined gravimetrically, corrected for the relative density of the liquid.
10 Markings and labels

B.2.2.2. Fill the burette with water, open the burette tap and let the water through the silicone rubber tube filling clamp; leave the burette empty.
B.2.2.3. Insert the external needle of the blood collection needle/needle holder assembly through the wall of the silicone tubing until the needle enters the lumen of the tubing.
B.2.2.4. Connect the container to the needle/holder assembly according to the container manufacturer's instructions.
B.2.2.5. Fill the container for at least one minute or as directed by the manufacturer.
B.2.3. Test criteria
The container may pass the test if the volume of water drawn in is ±10% nominal capacity.
AT 3. Minimum free space test
B.3.1. Test conditions
B.3.1.1. The tests shall be carried out at an atmospheric pressure of 101 kPa and an ambient temperature of 20°C; when testing under other conditions, corrections must be made.
B.3.1.2. Unused containers should be tested.
B.3.2. Test procedure
B.3.2.1. With the stopcock closed, separate the silicone tubing from the burette outlet cock and fill the burette with water if necessary.
B.3.2.2. Place the open tube under the burette outlet valve.
B.3.2.3. Pour water until the water level reaches the neck of the test tube.
B.3.2.4. Record the volume of released water to the nearest ±0.1 ml.
Determine the minimum headspace by subtracting the volume of water drawn in during the volume draw test (see B.2) from the total volume of water drawn from the burette.
B.3.3. Test criteria
The container is considered to have passed the test if, assuming that the free space available for mixing the contents of the container is limited by the bottom surface of the stopper and the meniscus of the liquid, such a space is not less than indicated in Table 1 for containers of the type tested.
NOTE Stoppers vary in shape and, in particular, their blood-contact side may protrude from the neck of the tube, separate, or have a pronounced concave or convex profile. These shape features can affect the available headspace, which must be taken into account when interpreting the test results. If necessary, the influence of the cork geometry can be determined by measuring, for example, the length of the occluding portion of the cork or the excess volume due to the concave shape of the cork.
