It is standard procedure for scientists to publicly make available their data for other scientists to also analyze it. However, in the case of the C-14 labs, they would not disclose their data. The data was kept secret for more than 29 years! It took legal action against the British Museum for them to eventually and reluctantly release the data.
For more than 29 years, every request for the release of the raw data from the three laboratories that performed the radiocarbon dating of the Shroud of Turin in 1988 was declined. Then, in 2017, French Shroud researcher Tristan Casabianca used the Freedom of Information Act in the United Kingdom that compelled the British Museum to finally release the long awaited data. The British Museum had acted as the formal supervisor of the three laboratories (Oxford, Zurich and Arizona) during the process and apparently, maintained the archive of all the data.

It was only in 2017 has the raw data of the 1988 C-14 dating been made available for other scientists to be able to analyze it.
“In 1988, three laboratories performed a radiocarbon analysis of the Turin Shroud. The results, which were centralized by the British Museum
and published in Nature in 1989, provided ‘conclusive evidence’ of the medieval origin of the artefact. However, the raw data were never
released by the institutions. In 2017, in response to a legal request, all raw data kept by the British Museum were made accessible.

“Three laboratories performed a radiocarbon analysis of the Turin Shroud,” according to Casabianca. “The results, which were centralized by the British Museum and published in Nature in 1989, provided ‘conclusive evidence’ of the medieval origin of the artefact. However, the raw data were never released by the institutions,” he wrote.In 2017, Casabianca submitted a Freedom of Information request to the British Museum and was allowed to see the data.

Why would the British Museum want to hide the raw data? Why would it have to take legal action to get the raw data on the C-14 testing of the shroud?
