The textbook context provides information about the Bureau of Indian Standards in the matching exercise (item vii), identifying it as the 'Agency that develop standards for goods and services.' Additionally, the True/False section explicitly states that 'Hallmark is the certification maintained for standardisation of jewellry.' The text also explains that organisations monitor and issue certificates like ISI, Agmark, and Hallmark, allowing producers to use these logos when they follow certain quality standards. However, the specific organisation providing ISO certification is not explicitly named in the given context.
