This standard specifies rquirements for vernier callipers reading 1to 0.1 (1/10), 0.05 (1/20)and 0,02 (1/50) mim, and having measuring ranges s given in Table 1. Requirements for materials and properties, basic design. accuracy and finish are also specified. NOTE: Notes o methods for teosing the o imperunt feaues of vemier callpers此given in Appendis A.

This standard specifies the sizes and performance requirements for both precise and coarse vials for spirit levels. The vials are for use in instruments for precision surveying, inspection, and general levelling. Ranges for the parameters of spirit level vials are related to the sensitivity of the vial, and preferred sets of parameters for given sensitivities

This Standard specifies requirements for aluminium ingots and aluminium alloy ingots and castings. NOTE: Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are contained in Appendix A.

This Standard sets out a code of practice for the retreading of pneumatic diagonal and radial ply tyres, including requirements for initial inspection, processing,marking and final inspection. It also sets out requirements for in-service repairs to tyres and repairs made in conjunction with the retreading process. NOTES: 1 It is a fundamental requirement of this

This Standard specifies methods by which transverse (circumferential) tensile properties of a section of a round steel pipe (tube) may be determined or proven to be above specified values. The methods permit the use of both short-length and long-length pipe test pieces, but they preclude spirally welded pipe.

This International Standard specifies requirements for two types of malleable cast iron, namely whiteheart malleable cast iron and blackheart malleable cast iron, used in the manufacture of castings. Classification is given for each type of malleable cast iron on the basis of mechanical properties determined on separately cast test pieces. This International Standard is applicable

This International Standard specifies the properties of unalloyed and low-alloyed grey cast irons used for castings, which have been manufactured in sand moulds or in moulds with comparable thermal behaviour. This International Standard specifies the characterizing properties of grey cast iron by either a) the tensile strength of separately cast samples, or if agreed by
