Microbiology of food and animal feeding stuffs. Horizontal method for the enumeration of mesophilic lactic acid bacteria. Colony-count technique at 30°C1 Scope This International Standard specifies a horizontal method for the enumeration of viable mesophilic lactic acid bacteria by counting the colonies growing in a solid medium after incubation at 30 C for 3 days. NOTE In some food products, there exist psychotrophic or thermophilic lactic acid bacteria necessitating culture temperatures different from 30 C. Moreover, not all lactic acid bacteria grow on MRS agar at pH 5,7 and some grow only weakly.

BS EN 2591-6405 on the method to test optical connector endurance of axial loads is useful for:

but is further constrained to address the needs of distribution of D-Cinema content to exhibition sites

This document is limited to specifying the requirements when applying lubricants to the wheel-rail interface between the wheel flange and the rail gauge corner (active interface) either directly or indirectly to the wheel flange or to the rail

Using BS 2SP 77 TO 2SP 80 guidelines

The materials and dimensions mentioned in BS EN 853 are useful in designing and assembling these wire braid reinforced hydraulic hoses

What’s new about BS EN 1706:2020

BS EN IEC 63171‑1 is the first part of connectors for electrical and electronic equipment

Manual (non-driven) and automated CMMs

Contents of BS IEC 60462:

Its determination requires additional chemical processing of the sample (such as chemical oxidation or combustion)

and public security

PD CEN/TR 16721 also gives recommendations for the further development of European Standards for the determination of the bio-based content
