Standards
This standard establishes requirements for grades of paddy, cargo rice, milled rice; cargo parboiled rice and milled parboiled rice. It also specifies the general conditions for sampling and the methodologies for assessing the various factors used in the determination of the quality of rice.
This standard specifies legal metrology requirements for labelled packaged commodities with constant nominal content and subject to international trade. It also covers sampling plans for net content verification of goods declared in units of mass or volume.
This Recommendation specifies
· legal metrology requirements for prepackaged products (also called prepackaged commodities or prepackaged goods) labeled in predetermined constant nominal quantities of mass, volume, linear measure, area, or count, and
· sampling plans and procedures for use by legal metrology officials in verifying the quantity of product in prepackages.
NOTE: The sampling plans are not recommended for use in the quantity control processes of the packer.
This standard specifies the requirements and methods of test for liquid household chorine bleaches.
This standard specifies requirements, including dimensions, materials, finish and selection for sampling for wire nails and cut nails. The following types of wire nails are covered by this standard: (a) Round plain head nails; (b) Round lost head nails; (c) Clout or slate nails; (d) Extra large head clout or felt nails; (e) Convex head roofing nails (chisel or diamond points); (f) Pipe nails (chisel point); (g) Panel pins; (h) Hardboard panel pins (round shank); (i) Hardboard panel pins (square shank); (j) Lath nails; (k) Plasterboard nails (jagged shank); (l) Oval brad head nails; (m) Oval lost head nails; (n) Tile pegs; (o) Tram nails with flat or raised head with chisel point; (p) Spring head twisted shank nails; (q) Square twisted shank flat head nails; (r) Washer head slab nails; (s) Dowels; (t) Annular ringed shank flat head nails; (u) Helical threaded shank flat head nails; and (v) Duplex head nails. The following types of cut nails are covered by this standard: (a) Cut clasp nails; and (b) Cut floor brads. The types of nail covered are illustrated in Tables 1 to 25 and in the corresponding diagrams, Figures 1 to 25.
1.2 Concrete masonry units covered by this specification are made from lightweight or normal weight aggregates, or both.
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.
This specification covers hollow and solid (see 5.3 and 5.4) concrete masonry units made from hydraulic cement, water, and mineral aggregates with or without the inclusion of other materials. There are three classes of concrete masonry units: Normal Weight, Medium Weight, and Lightweight. These units are suitable for both load bearing and non-load bearing applications. This standard covers hollow blocks from sizes of 3in. (76.2mm) to 8 in. (203.2mm).
Concrete masonry units covered by this specification are made from lightweight or normal weight aggregates, or both.
This standard specifies requirements for hollow non-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) Light weight. It also covers the sampling and testing of hollow non-load-bearing concrete masonry units for compressive strength, absorption, weight, moisture content and dimensions. It does not cover blocks intended solely for decorative purposes.
These requirements cover ballasts of the resistance, reactance, and electronic (solid state) types for use with fluorescent lamps involving a potential of 2500 volts or less in accordance with the National Electrical Code, NEPA 70. A fluorescent lamp ballast may be determined by investigation to be acceptable for use, in a fixture or other device, with electric-discharge lamps of other than the fluorescent type. A product that contains features, characteristics, components, materials, or systems new or different from those in use when the standard was developed, and that involves a risk of fire, electric shocks, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the level of safety for the user of the product as originally; anticipated by the intent of this standard.
