Assess the quality of automotive glazing related materials

Business Sectors (Suites): Automotive Glazing
Developed by: IMI
Approved on: 30 Mar 2020


This standard is about being able to make an assessment of the quality of glass-related materials, including those materials that are either glass or are associated with their use.  Candidates need to be able to identify the main characteristics of the glass-related materials that they work with, and to ensure that the materials match the specifications required by the work being undertaken.  They need to be able to detect any obvious variations, such as defects in the manufacture of the materials that could adversely affect the work.  They also need to be able to identify the most likely causes of these variations, and make recommendations to correct them to the appropriate people.

Performance criteria

You must be able to:

P1 obtain the correct specification for the glass-related materials
P2 assess the quality of glass-related materials using appropriate equipment and methods
P3 ensure the equipment used to assess quality is functioning correctly
P4 identify the main characteristics and features of the glass-related materials
P5 check that the glass-related materials accord with the information on them
P6 report any discrepancies to the appropriate people according to standard operating procedures
P7 examine the glass-related materials for variations in quality using the correct methods
P8 ensure the equipment used in the examination process is appropriate
P9 identify correctly any variation between the quality of the glass-related materials and the specification
P10 ensure the quality assurance results are recorded correctly in the appropriate information systems
P11 access all relevant information on the causes of the variation in glass-related materials
P12 identify the most likely causes of the variation in glass related materials, and prioritise investigations accordingly
P13 correctly identify the causes of the variation
P14 obtain expert assistance when the causes of the variation cannot be identified
P15 identify suitable solutions for rectifying the causes of the variation
P16 ensure quality assurance results are recorded correctly in the appropriate information systems
