Standards
This specification covers poly(vinyl chloride) (PVC) pipe made in Schedule 40, 80, and 120 sizes and pressure-rated for water (see Appendix X1). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given.
This specification covers poly(vinyl chloride) (PVC) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water (see appendix). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given.
This standard defines working positions and makes it possible to locate welds in space with reference to the horizontal reference plane (usually parallel to the workshop floor) by means of angles of slope and rotation which are independent from surrounding construction.
This standard gives recommendations on the serviceability of buildings against vibrations. It covers three recipients of vibrations: a) human occupancy in buildings and on pedestrian bridges; b) the contents of the building; c) the structure of the building. It applies to buildings, pedestrian bridges and walkways found within buildings or connecting them and does not include bridges that carry vehicular traffic, nor the design of foundations or supporting structures of machinery.
This standard specifies
attachment fused and unfused plugs (caps), shuttered receptacles (sockets) for
flush surface mounting. These plugs and sockets are suitable for alternating
current circuits only of voltages not exceeding 250 volts and currents not
exceeding 15 amperes. The plugs and
receptacles covered by this standard are intended for use in making readily detachable
electrical connections in non-hazardous locations between supply circuits and
portable lamps, appliances and similar equipment.
The standards and requirements in this document are the pre-requisite conditions for the issuance of a Technical Acceptance certificate (TAC) for television broadcasting transmitters.
This standards covers thermoplastic and rubber tapes for use as electrical insulation at not more than 600 V and at 80C (176 F) and lower temperatures on joints and splices in wires and cables in accordance with the National Electrical Code. It is intended that rubber tape on a joint or splice be mechanically protected by a covering such as friction tape . Thermoplastic tape is acceptable without the additional mechanical protection.

BESP 100, Issue 1, November 1, 1996. This procedure describes the process for obtaining a Technical Acceptance Certificate (TAC) for Broadcasting Equipment.
This standard specifies performance requirements for hollow load-bearing concrete masonry units made from Portland cement, water and mineral aggregates with or without the inclusion of other materials. It covers three weight classifications of the concrete masonry units: (a) normal weight; (b) medium weight; and (c) lightweight.
