SIST EN 988:1998

SIST EN 988:1998 is a Slovenian standard from SIST for zinc and zinc alloys used as rolled flat products for building. It specifies the material and size limits for strip, sheet, and cut length made from zinc-copper-titanium alloy, so manufacturers, purchasers, and specifiers can check whether a product falls within the standard’s field of use.

What does SIST EN 988:1998 specify?

SIST EN 988:1998 covers rolled flat products for building purposes made from zinc-copper-titanium alloy. The standard applies to products supplied as strip, sheet, or cut length, and it sets the dimensional range in which those products are covered.

The scope limits the standard to products from 0.6 mm up to and including 1.0 mm thickness and from 100 mm up to and including 1000 mm width. It also excludes formed or shaped products and products prefabricated by any method other than cutting or size reduction. In practice, that matters because the document is meant for flat feedstock and cut-to-size material, not finished formed components.

What are the key requirements of SIST EN 988:1998?

The main requirements are the scope limits that define which zinc products are covered. For a buyer or quality manager, the key question is whether the offered material matches the alloy, form, and dimensions stated by the standard.

• Material - SIST EN 988:1998 applies to zinc-copper-titanium alloy. This tells the reader which alloy family is intended for compliance checking.
• Product form - The standard covers strip, sheet, and cut length. This matters because the product must be supplied as a flat rolled product, not as a finished shaped part.
• Thickness range - The covered products are from 0.6 mm to 1.0 mm inclusive. In practice, thickness has to be checked against the order, inspection records, and delivery documents.
• Width range - The covered products are from 100 mm to 1000 mm inclusive. This is a practical purchase check, especially for incoming inspection and product identification.
• Exclusions by form - Formed or shaped products are outside the scope. That means a part that has already been bent, pressed, or otherwise shaped is not the product type addressed by this standard.
• Exclusions by prefabrication method - Products prefabricated by any means other than cutting or size are outside the scope. For users, this separates simple cut-to-size material from more processed building elements.

What terms does SIST EN 988:1998 define?

The document uses a small set of core terms that readers should interpret consistently.

• Rolled flat products - Flat metal products supplied in rolled form, rather than as formed profiles or finished parts.
• Strip - A flat product supplied in a narrower continuous form within the standard’s width range.
• Sheet - A flat product supplied in a broader continuous form within the same covered range.
• Cut length - Flat material supplied in fixed lengths after cutting.
• Formed or shaped products - Products that have been given a shape beyond simple cutting to size.
• Zinc-copper-titanium alloy - The alloy family named by the standard as the covered material.

Who uses SIST EN 988:1998?

SIST EN 988:1998 is used by manufacturers, buyers, inspectors, and specifiers involved with building materials made from zinc and zinc alloys. It is relevant when ordering, receiving, or checking flat zinc products for building use.

In practice, production and quality teams use it to confirm that the supplied material matches the covered alloy and falls within the permitted thickness and width range. Purchasing staff use it to describe what they need in contracts or purchase orders. Technical specifiers use it to select a suitable rolled flat product for building applications.

What changed in SIST EN 988:1998 from the previous edition?

SIST EN 988:1998 is identified as identical to EN 988:1996. The Slovenian standard therefore adopts the European standard without change.

What does the SIST EN 988:1998 document contain?

The document presents the standard in Slovenian, English, German, and French title forms, followed by the scope statement. It also identifies the standard as identical to EN 988:1996 and classifies it under ICS 77.150.60 for lead, zinc and tin products.

For a user, the useful content is the scope and identification of the covered product type, dimensions, and exclusions. For cataloging and document control, the publication data and ICS classification help locate and file the standard correctly.
