Milk products - Enumeration of bifidobacteria - Colony-count technique (ISO 29981:2024)

This document specifies a method for the selective enumeration of bifidobacteria in milk products by using a colony-count technique at 37 °C under anaerobic conditions. The method is applicable to milk products, such as fermented (e.g. yoghurts) and non-fermented milks (e.g. pasteurized milks, skim milks, whey protein concentrates), milk powders and formulae (e.g. infant formulae, follow-up formulae for older infants, products for young children) where these microorganisms are present and viable, in combination with other lactic acid bacteria or alone. The method is also applicable to starter and probiotic cultures. For proposed quality criteria of dairy products, see, for example, CXS 243-2003. Bifidobacteria used in milk products usually belong to the following species (e.g. References [7] and [10]): — Bifidobacterium adolescentis; — B. animalis subsp. animalis; — B. animalis subsp. lactis; — B. bifidum; — B. breve; — B. longum subsp. infantis; — B. longum subsp. longum.

Stainless steel needle tubing for the manufacture of medical devices - Requirements and test methods (ISO/DIS 9626:2025)

ISO 9626:2016 applies to rigid stainless steel needle tubing suitable for use in the manufacture of hypodermic needles and other medical devices primarily for human use. It provides requirements and test methods for the tubes manufactured for needles as component used in medical devices. Additional performance testing on the tube aspect may be required when the component is incorporated in the ready-to-use device. It specifies the dimensions and mechanical properties of steel tubing of designated metric sizes 3,4 mm (10 Gauge) to 0,18 mm (34 Gauge). It does not apply to flexible stainless steel tubing because the mechanical properties differ from those specified for rigid tubing in ISO 9626:2016. However, manufacturers and purchasers of flexible tubing are encouraged to adopt the dimensional specifications given in ISO 9626:2016.

Plastics piping systems for non-pressure underground conveyance and storage of surface water - Boxes used for infiltration, attenuation and storage systems - Part 1: Specifications for boxes made of PP and PVC-U

This document gives the definitions and specifies the minimum requirements for injection moulded, extruded and thermoformed thermoplastics cuboid shaped boxes, including integral components, used in underground systems for infiltration, attenuation and storage of surface water (e.g. storm water) and manufactured from polypropylene (PP) or unplasticized polyvinylchloride (PVC-U). Product properties are determined by a combination of material specifications, design and manufacturing process. These boxes are intended for buried underground use, e.g. in landscape, pedestrian or vehicular traffic areas. A box can either be factory assembled, or site assembled from different components. These boxes are intended to be used as elements in a modular system where the manufacturer states in the documentation how the components are assembled to create a complete infiltration, attenuation or storage system. NOTE Non load bearing component(s) can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, thermoforming and low-pressure injection moulding.
