Notes: (1) Thermal cut-offs function once only and are used for…

Divides non-assembled strips into three quality grades that are identified by (+++), (++), (+) corresponding to the conditions specified in the tables. Designation or names for these quality grades may be assigned in national standards, provided that such standard indicate, at least in a note, the relationship with the ISO classification. Replaces Recommendation ISO/R 1324-1970 of which it…

1. Scope 1.1 General This Standard covers once-through high efficiency air-cleaning assemblies for maintaining radioactive particulate and radioiodine releases below licenced limits in nuclear power plants. The Standard identifies and establishes minimum requirements for the design, manufacture, installation, and preoperational acceptance testing for any or all of the following components…

Describes a method relating to fatigue under repeated deformations. Believed to be suitable for reasonably stable stress-strain properties. Materials to be tested must meet special criteria, otherwise experiment and interpretation may be difficult. Distinction should be made between this test and the flexometer tests of ISO 4666/1 to 3. Caution when relating standard test results to service…
