Introduction

Note: Nothing in this standard supersedes applicable laws and regulations.

Note: In the event of a conflict between the English and the domestic language, the English language shall take precedence.

For cylinder heads made of AlSi casting alloys according to

• GMW5M-AL-C-P-Si9Cu3-F

• GMW5M-AL-C-P-Si10Mg-F

• GMW5M-AL-C-P-Si6Cu4Mg-F

Mission / Theme. This document describes the component-relatedmodifications to thematerial specifications:

GMW5M-AL-C-P-Si9Cu3-F

GMW5M-AL-C-P-Si10Mg-F

GMW5M-AL-C-P-Si6Cu4Mg-F

It serves as an acceptance standard for visual tests of porosity and flaws in machined and unmachined cylinder head surfaces.

Specifications concerning the surface condition, e.g. roughness, rippling and evenness of prepared surfaces, are not included in this document and shall be specified by drawing.

Classification. Not applicable.
