ASTM C772-03 (2014) rus PDF

Full title and description

St ASTM C772‑03 (2014) rus — Russian-language edition of ASTM C772‑03 (Reapproved 2014), "Standard Test Method for Oil Migration or Plasticizer Bleed‑Out of Preformed Tape Sealants". This product page describes the test method, its purpose, principal test conditions and intended application for preformed tape sealants; the entry refers to a Russian translation of the ASTM test method text.

Abstract

ASTM C772 is a short laboratory test method that determines whether preformed tape sealants exhibit oil migration or plasticizer bleed‑out when heat‑aged on filter paper. The procedure uses small pads of tape sealant placed on filter paper, heat‑aging at defined temperatures, and visual assessment of staining or migration into the paper. The method is intended as an indicator test for potential staining or bleed behavior of tape sealants under accelerated conditions.

General information

• Status: C772‑03 — reapproved in 2014 (document commonly referenced as C772‑03 (2014)); some catalog listings note withdrawal/revision history — consult ASTM International for the definitive current status.
• Publication date: Original designation C772‑03 (2003); reapproval recorded 2014 (commonly shown as 01 June 2014 for reapproval/published notice).
• Publisher: ASTM International (American Society for Testing and Materials).
• ICS / categories: 91.100.50 — Binders; sealing materials (building seals and sealants test methods).
• Edition / version: C772‑03 (Reapproved 2014) — Russian translation edition indicated by "rus".
• Number of pages: Very short test method (typically 1–4 pages in ASTM presentation; many vendor/catalog records show 2 pages for the core method).

Scope

The test method covers a laboratory procedure to indicate the presence and extent of oil migration or plasticizer bleed‑out from preformed tape sealants. It specifies sample preparation, use of high‑grade rapid filter paper, controlled heat‑aging (commonly at 70 °C or 100 °C), and visual examination of migration/staining. The method is intended as an indicator; it does not address all safety concerns or all field conditions and is meant for quality control and comparative evaluation rather than absolute lifetime prediction.

Key topics and requirements

• Test purpose: detect oil/plasticizer migration (bleed‑out) from preformed tape sealants.
• Specimen prep: small pads of tape (minimum dimensions specified), tested with release liner in place as required by the procedure.
• Test media: high‑grade rapid filter paper sheets to receive any migrating oil/plasticizer.
• Aging conditions: ventilated air‑circulating oven; typical temperatures 70 ±2 °C (158 °F) or 100 ±2 °C (212 °F) for specified times.
• Apparatus: oven conforming to ASTM E145, 1 kg weight for compression where specified, standardized filter paper diameter and quantity.
• Evaluation: visual inspection for staining or migration; method provides pass/observe criteria rather than quantitative chemical extraction.
• Referenced standards: terminology and related test methods referenced (for example ASTM C717, ASTM D2203, ASTM E145 as cited in the method).

Typical use and users

Used by manufacturers of preformed tape sealants and butyl/adhesive tape products, quality control and R&D laboratories, building envelope specifiers, independent test laboratories and product certification bodies. Typical applications include pre‑production QC checks, comparative screening of formulations, and documentation of staining tendency for product literature or specifications.

Related standards

ASTM C772 is typically used alongside or references these standards: ASTM C717 (Terminology of Building Seals and Sealants), ASTM D2203 (Test Method for Staining from Sealants) and ASTM E145 (Specification for Gravity‑Convection and Forced‑Ventilation Ovens). Related tape/sealant standards and AAMA or industry guidance on sealant/tape performance may also be relevant.

FAQ

Q: What is this standard?

A: ASTM C772 is a test method that indicates whether preformed tape sealants release oils or plasticizers that migrate into adjacent substrates, assessed by placing specimens on filter paper and heat‑aging under controlled conditions.

Q: What does it cover?

A: It covers sample preparation, required apparatus (oven, filter paper, weights), specified aging temperatures and visual evaluation procedures to reveal oil or plasticizer migration; it is an indicator test rather than a full durability or chemical analysis method.

Q: Who typically uses it?

A: Sealant and tape manufacturers, product development and QC laboratories, building envelope specifiers, test labs and certification bodies evaluating staining or bleed tendencies of preformed tapes.

Q: Is it current or superseded?

A: The designation C772‑03 was reapproved in 2014 and widely cited in that form; some catalogues show later administrative actions or withdrawal notices in repositories. For the authoritative current status, obtain confirmation directly from ASTM International. The Russian translation here follows the C772‑03 (reapproved 2014) text.

Q: Is it part of a series?

A: It is part of ASTM Committee C24 test methods for building seals and sealants and is used alongside related ASTM test methods and terminology standards (for example C717, D2203, E145).

Q: What are the key keywords?

A: Oil migration, plasticizer bleed‑out, preformed tape sealants, filter paper, heat aging, staining, tape sealant testing.
