Neurosurgical implants. Sterile, single-use hydrocephalus shunts and components Ingestion-build-61878 BS 4444 on electrical earth

BS 4444 on electrical earth monitoring and protective conductor is relevant to:

consisting of one base coat

The diagnostic tests employed in the fixed time frame method are restricted to destructive tests

protective systems and components are operated in line with their intended use and are installed and maintained according to the relevant codes of practice or requirements

even a short-term exposure to water can be sufficient to weaken the adhesion of a coating film either to the substrate or within the coating system

Neurosurgical implants. Sterile, single-use hydrocephalus shunts and components Ingestion-build-61878 BS 4444 on electrical earth1 Scope This International Standard specifies safety and performance requirements for sterile, single use non active hydrocephalus shunts and components. This includes the components used in shunts, like valves, tubes and reservoirs. This International Standard gives no recommendation concerning the superiority of a certain type of valve. For manufacturing, it defines the mechanical and technical requirements. This International Standard defines the
