The work of preparing International Standards is normally carried out through ISO technical committees. Eac

16、h member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internation

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the differen

ISO 2017 All rights reserved v ISO 8336:2017(E) Introduction The purpose of this document is to provide manufacturers and purchasers with uniform requirements for fibre-cement flat sheet products. These requirements are performance-based and have been specif

23、ied with the objective of ensuring product quality, industry efficiency and the performance of the product in service. ISO/TC 77 aims to harmonize this document, where possible, with other national fibre-cement standards (CEN, ASTM and JIS) to facilitate and promote uniform performance benchmarks fo

Sampling levels and acceptance criteria are specified in Clause 6. 3.2 type test test carried out to demonstrate conformity with the requirements of this document or for the approval of a new product and/or

37、cted product exceeds the specification. This type of specification provides the consumer with a clearly defined lower quality boundary; this does not occur if acceptance is based solely on the average value of the measured property.
