D5900 specifies the Physical and Chemical properties of Industrial Reference Materials (IRM). The IRM 3-TBBS inventory has been depleted and needs to be replenished. However, after checking with a number of suppliers ( 8) not one is able to produce TBBS within the current IRM 3 specifications (D5900 - Table 3). Therefore, a survey of the market was conducted which resulted in the committee wanting to update the IRM 3 Assay from 96 minimum to 95 minimum which will align with current TBBS production.
