ISO Metric Thread Tolerance Tables. The information below can be used to calculate the values of thread tolerances defined by ISO 965/1. Tolerances are written as a combination of a tolerance band, signified by an alphabetic letter (E, G, e, f, g or h, with uppercase letters signifying internal threads, and lowercase signifying external), and a tolerance class, signified by a number.

Bleeding should not be excessive. Limits to the amount of bleeding is given in the specifications. Photo 8.1: Loss of durability due to excessive bleeding. In the above Photo 8.1 of the bottom flange of a precast beam, the concrete has bled excessively due to very poor grading of the sands in the mix.
Check List for Batch Plant Inspection. The detailed check list presented was developed for use by concrete inspectors. The check list, when properly used, will familiarize the inspector with the batch plant, will indicate any items not complying with the specifications, and will indicate items not considered sound batching and mixing procedures.

8.3.1 Introduction. As stated in Section 8.1, an internal system for quality control is needed to ensure that valid data continue to be produced. This implies that systematic checks, e.g. per day or per batch, must show that the test results remain reproducible and that the methodology is actually measuring the analyte or attribute in each sample.
