ISO/IEC 18033 specifies encryption systems (ciphers) for the purpose of data confidentiality. ISO/IEC 18033-3:2005 specifies block ciphers. A block cipher is a symmetric encipherment system with the property that the encryption algorithm operates on a block of plaintext, i.e. a string of bits of a defined length, to yield a block of ciphertext. ISO/IEC 18033-3:2005 specifies the following…

ISO 24370:2005 specifies a test method for determining the fracture toughness of monolithic ceramic materials at room temperature by the chevron-notched beam (CNB) method. ISO 24370:2005 is applicable to monolithic ceramics and whisker- or particulate-reinforced ceramics that are regarded as macroscopically homogeneous. It is not applicable to continuous-fibre reinforced ceramic composites. ISO…

ISO/ASTM 51608:2005 outlines the installation qualification program for an X-ray (bremsstrahlung) irradiator and the dosimetric procedures to be followed during operational qualification, performance qualification and routine processing to ensure that the entire product has been treated within a predetermined range of absorbed dose. Other procedures related to operational qualification,…

ISO 18437-2:2005 defines a resonance method for determining from laboratory measurements the dynamic mechanical properties of the resilient materials used in vibration isolators. It is applicable to shock and vibration systems operating from a fraction of a hertz to about 20 kHz. ISO 18437-2:2005 is applicable to resilient materials that are used in vibration isolators in order to reduce --…

ISO 18437-3:2005 defines a cantilever shear beam method for determining from laboratory measurements the dynamic mechanical properties of the resilient materials used in vibration isolators. Common errors due to clamping the specimen are avoided by using fixed ends so there is no rotational motion of the beam at its ends. This part of ISO 18437 is applicable to shock and vibration systems…

ISO 17641-2:2005 specifies the required specimens, the test piece dimensions and the procedures to be followed to carry out self-restraint hot cracking tests. The following tests are described: T-joint weld cracking test;weld metal tensile test;longitudinal bend test. The tests are designed to provide information about the hot cracking sensitivity of weld metals. The tests are not suitable for…

ISO/TR 17641-3:2005 outlines the test methods and procedures for carrying out externally loaded tests to assess susceptibility to hot cracking. The following tests are described: Hot tensile testsVarestraint and Transvarestraint testFlat tensile test. The above tests can provide information about the hot cracking sensitivity of parent materials, weld metals and weldments. Assessment is based upon…

ISO 16269-6:2005 describes procedures for establishing tolerance intervals that include at least a specified proportion of the population with a specified confidence level. Both one-sided and two-sided statistical tolerance intervals are provided, a one-sided interval having either an upper or a lower limit while a two-sided interval has both upper and lower limits. Two methods are provided, a…

ISO 17642-2:2005 specifies the sizes of the test pieces, the specimens and the procedures for carrying out self-restraint cold cracking tests by: CTS (controlled thermal severity) test Tekken (Y-groove) or Lehigh (U-groove) test in order to obtain information about the cold cracking sensitivity during welding. This International Standard applies primarily, but not exclusively, to C-Mn and low-…
