Methods of test for rigid cellular materials - Methods 7 to 9What is BS 4370 2 Methods of test for Rigid cellular materials about? BS 4370 2 is the second part of the multi series standard that describes three methods of test which apply to rigid cellular products of polymeric origin: Methods 7A and 7B. Measurement of thermal conductivity Method 8. Measurement of water vapour transmission Method 9. Determination of tensile strength NOTE The methods may not be suitable for cellular products of inorganic origin.

but are not limit to:

industrial-process measurement and control systems or parts of systems that may be exposed during operation

BS EN 10305-1 exemplifies the required chemical composition

It describes the characteristics of sulfuric acid and specifies the requirements and the corresponding test methods for sulfuric acid

— initial verification

ISO 4643:1992

messages conforming to this International Standard may be considered by some user communities to meet their needs for purposes outside this scope

use and interpretation of results when using biological indicators can be found in ISO 14161

BS 7212 on safe use of construction hoists useful for:

enabling you to assess PS recyclates for an effective recycling process

the provision of an additional route to compliance with hardware fault tolerance

including “lessons learned”
