The retention period for laboratory records shall comply with contractual obligations. Access to records shall comply with confidentiality obligations, and the records shall be readily available. Clause 4.5.11 of RB/T 214 – Record Control: Testing and inspection organizations shall establish and maintain record management procedures to ensure that the technical records related to each testing and inspection activity contain sufficient information, and to ensure that the identification, storage, protection, retrieval, retention, and disposal of records meet the required standards. What pen should be used to write on original records? The guidelines state that there is no specification regarding the type of pen to be used for writing on original records; they only require that such records be written in a way that prevents damage, deterioration, or loss, and ensures traceability. In theory, any pen that can meet these requirements can be used to record on original records. In practice, laboratories can specify in their procedural documents which type of pen should be used for writing. For example, some laboratories require that all original records in the laboratory be written using a signature pen. Write the records in a blue pen – were non-conformities identified? During the actual review process, some laboratories used blue ink pens to write the original records, which resulted in non-conformities being identified. Why is that? The reason is not that blue ink pens cannot be used for writing original records; rather, the laboratory’s own procedural documents specify that black ink pens should be used for writing such records. In practice, however, the laboratory used blue ink pens, which means that the procedures set out in those documents were not followed – it’s not that blue ink pens cannot be used for original records at all. Can pencils be used for making preliminary records? Pencils can be used for making preliminary notes! Some industries have specific requirements to use pencils for initial recordings; for example, marine systems stipulate that records must be made in pencil. It may seem strange, but durability is the main consideration. No matter what type of pen it is, it will become blurred when exposed to seawater, except for pencils; therefore, marine regulations stipulate that pencils must be used for recording. Some people might think that pencils can be erased, so they cannot be used for taking notes; public accounts serve as a good reminder that pencils allow for permanent recording. Among world-famous paintings, those drawn in pencil are the best-preserved, mainly due to the stable chemical properties of graphite in pencils. Original ballpoint pens tend to \"seep ink,\" so their use is generally not recommended.
