Plastics piping systems for water supply and for buried and above-ground drainage and sewerage under pressure. Unplasticized poly(vinyl chloride) (PVC U) - Valves1 Scope This part of ISO 1452 specifies the characteristics of valves made from unplasticized poly(vinyl chloride) (PVC U) for piping systems intended for water supply and for buried and above ground drainage and sewerage under pressure. It also specifies the test parameters for the test methods referred to in this part of ISO 1452. In conjunction with ISO 1452 1, ISO 1452 2, ISO 1452 3 and ISO 1452 5 it is applicable to PVC U valves with components

Signs specified as Category B signs are judged by Technical Committee PH/8 to require the further education of intended viewers before they can be registered as approved safety signs

The selection of the test method is optional

ISO 6469‑1 specifies the safety requirements of RESS for climatic conditions

This assumption is done

ISO 20685‑1 is the first part of a multi-part series that addresses protocols for the use of 3-D surface-scanning systems in the acquisition of human body shape data and measurements defined in ISO 7250-1 that can be extracted from 3-D scans
