ISO 3438:2003 lays down the dimensions of subland twist drills with Morse taper shanks for holes prior to tapping screw threads. The drills have been designed to produce holes prior to tapping metric threads (coarse pitch series) over a selected range of M8 to M30. ISO 3438:2003 complements ISO 2306.

ISO 3439:2003 lays down the dimensions of subland twist drills with cylindrical shanks for holes prior to tapping screw threads. The drills have been designed to produce holes prior to tapping metric threads (coarse pitch series) over a selected range of M3 to M14. ISO 3439:2003 complements ISO 2306.

ISO 17635:2003 gives guidance on the selection of method(s) for non-destructive testing of fusion welds in metallic materials based on material, weld thickness, welding process, quality control requirements and extent of testing. It specifies standards to be applied to the different types of testing and general rules for either the methodology or the acceptance level for metallic materials. The…

ISO 17637:2003 covers the visual examination of fusion welds in metallic materials. It may also be applied to visual examination of the joint prior to welding.

1. Scope 1.1 This Standard covers welding requirements for carbon and low-alloy welded steel construction, with the exception of those types listed in Clause 1.2. Requirements that are essentially common to all such structures are covered in Clauses 1 to 10, while provisions applying specifically to statically loaded structures and to cyclically loaded structures are included in Clauses 11 and…

ISO 13641-2:2003 specifies a screening method for assessing the potential toxicity of substances, mixtures, surface waters, groundwaters and wastewaters, effluents, sludges, or other environmental samples by determining the production of biogas (carbon dioxide and methane) from muds, sediments and other anaerobic environments with low biomass concentration. The growth rate of anaerobic bacteria…

ISO 13555-1:2002 establishes the preconditioning phase of the procedure for checking the dynamic setting of fuel injection equipment fitted to diesel engines, this preconditioning being carried out prior to the dynamic timing measurement of the fuel injection pump setting according to ISO 13555-2.

ISO 16871:2003 specifies a method for exposing plastics pipes and fittings, individually or assembled, or as pieces therefrom, to natural weathering in order to assess changes. The exposure is considered appropriate for evaluating components subject to yard storage prior to installation and use without further exposure to direct weathering, and is quantified to promote rationalization of exposure…

1. SCOPE 1.1 Organization and Content - This standard sets out requirements for the design and manufacture of packaging used for the transportation of infectious substances, diagnostic specimens, biological products or (bio) medical waste. There are three categories of packaging: Type 1A (UN Standard Infectious Substance Packaging), Type 1B and Type 1C. UN Standard Infectious Substance Packaging…

ISO 10381-4:2003 describes the sampling of soils of natural and near-natural sites;areas used for agriculture (arable and pasture sites);areas used for horticulture (including domestic gardens, allotments);areas used for special crop-cultivation, arboreal, vineyard, etc.;forest areas and woods. It is applicable to soil investigations and evaluations in the field;chemical, geochemical, physical,…
